Gisele’s Planned and Chaotic Arrival
When Ana and I were getting aware of the pregnancy we were living in France since April 2006 six weeks after Markus’ birth in Naperville. In late 2006 we had one big problem, we were green card holders thus not citizens and Gisele was going to be born in France. She was not going to be American if not born on American soil.
We drafted a plan to spend the summer in Boston and have her born while staying there. The only idea I had was to use the somewhat permanent address at Inman Street 31 with Sarah Cortes, where I was usually renting a room on a monthly basis for my frequent stays at MIT. Sarah agreed to rent out the uppermost floor to Ana and me and that was the plan. It turned out to be a quite solid basic plans, but the details were going to be quite chaotic.
We arrived in Cambridge as planned about 6 weeks before Gisele was due, which is the latest you are supposed to fly when pregnant, or is it? Well, this is what we thought. It was unclear what our home address was supposed to be. Inman Street did not seem right because we would never receive mail there and no name was on the door. So, we chose 77 Massachusetts Ave, which is clearly not a private address, but nobody ever said anything. I was worried a bit but then again, I was employed at MIT and the address was legit. It never turned out to be a problem which until today makes me wonder.
We spend a marvelous summer with the two boys in Cambridge and the area. They took to the US with ease and Ana walked them around Cambridge and Boston a lot, more then she ever did afterwards, in fact even myself spent more time in Boston and got to know Cambridge much better than in the eight years before. The boys and Ana visited me in the office several times. We thought about the delivery and we knew that we had to do something about our two little boys, Ivan was not even three years and Markus younger than one and a half. Whom could we hand those two over while Ana and I would be in the delivery room in the hospital (Brigham and Women’s in Boston by the way). We were looking for some baby sitters and Ana eventually made contact with a young woman from Mexico who could watch the kids while birth was taking place. Neither Ana nor I really seriously considered the possibility that I would watch them and Ana would do the delivery by herself. Retrospectively of course an option but we did not even think about that. I told Ana to get to know the young woman better but after a first meet the option sounded good enough and we thought we were set.
I am pretty sure the due date was pretty early in July, but Gisele held out for a good while and finally on July 14 Ana was sure the little baby girl (our first girl) was about to arrive. Unfortunately, due to the delays we somehow lost our baby sitter, she had to travel to Mexico, and we had no clue what to do. Through the hispanic connection Ana had though the phone number of a hispanic person called Fe who might be up for the job. She worked daytime in a shop on Mass Ave close to central square. Ana found her and left her with the kids it was late afternoon by then. This was after I made some frantic calls to my faculty colleague Peter Fisher whether he could help me out of a pickle but no luck! Finally, we were on our way to the hospital with a somewhat weird feeling leaving our little boys behind but then we also had to focus on Gisele. It took Ana a while to get going in Brigham and Women’s but eventually once it started it all went quick. Gisele appeared in this world on Saturday July 14, 2007 at 1:43 early in the morning. She was in great shape with way more hair than Markus even more than Ivan and we were thrilled! After the usual formalities eventually I realized that I had to get home to take care of the boys. I took a cab to get back to Inman Street and was wondering whether everything would be all right. The longer the ride took the more I got worried, of course not admitting to myself I was. Finally, I found Fe with our boys at around 6am in the morning mostly calm in our room. They were glad to see me, Fe looked somewhat exhausted, but not too bad. They seemed to have cuddled up in bed to sleep. Everybody was happy. I wrote Fe a check and that was it.
I was very relieved, and prepared our usual web site and send email to everybody about Gisele birth. I am not sure I really slept any, I just grabbed the boys put them into the stroller and walked from Inman Street all the way to the hospital; almost 3 miles but it felt good because otherwise I would have been very tired. I explained the boys on the way what had happened and told them that Mami was fine and that they had a new baby sister, Gisele. They were listening and interested but I could tell they did not really understand what happened. Eventually we made it to the hospital – me sweating and tired.
We found Mami’s room and knocked and then entered. Ivan and Markus went in carefully not sure what to expect. Ana was sitting in her bed exhausted but very happy with Gisele sucking and calling in excitement when the three of us walked in, of course mostly calling for our two boys 😉 Ivan approached Ana but Markus looked at the situation and turned around on his heel and ran out of the room. Ana and I looked at each other with huge eyes. Not really what we had expected. I ran after him and grabbed him and held him in my arm. He was not happy about this new baby, but we talked with him Ana and eye and eventually once Ana (his absolute favorite at the time) had embraced him and talked with him he looked at this suspicious new baby.
Late July 2007


Observation of Bs-Bsbar Oscillations — Core of my Tenure Case
The observation of Bs mixing (that is how we always referred to it) was more like an afterthought for me. My real goal for the Tevatron and the CDF experiment was supposed to be the Higgs boson search. It would take a while to have enough data therefore I thought of doing something interesting but reasonably quickly. Bs mixing seemed to be the perfect topic: a great physics goal as not much was known about the real value and it would be very plausible if something would not agree with the standard model as the CP sector was and still is suspect as it does not allow for an explanation of the observed matter-antimatter asymmetry. First studies with our trigger simulation (GenTrig) clearly indicated that it was doable pretty quickly. We estimated half a year but the real results with all the assumed parameters suggested that we should have enough data within 2 months.
Well it came differently as everybody knows today. We started data taking seriously in April 2001 and went through a depressing startup of the Tevatron in terms of the delivery of data. The silicon detector, an integral part of the analysis, would not work even close to what we were estimating and the two-track trigger was very sensitve to the beam positioning, which was on our scale far off its nominal position. These three main factor turned the quick analysis into a marathon which streched out until finally in September 22, 2006 I had the honour to announce the observation of Bs mixing at the required 5 standard deviation significance. We had a key crew of about 15 people pulling this analysis through with lots of people signing on but not contributing at an equivalent level (there were about 70 registered people).
We literally prepared this analysis through tens of precursor analyses and publications with thousands of pages of documentation. We spent probably several months in meetings presenting discussion and sometimes fighting. Lots of allnighters were pulled by many many people in the core team and we had the time of our life, in particular as the result just came together when I had to leave and start serious involvement in CMS. “Das Glueck ist mit dem tuechtigen” as I always say. Anyway, this photo has been taken when I announced our observation for the first time to the public, it was a very emotional experience for me.

The key scientific picture is of course this one which clearly shows that at a frequency around 17.8/ps the data suggests an amplitude of one significantly different from an amplitude of zero which would be consistent with no oscillations. Enjoy, this is the result of very hard and highly organized effort and an analysis masterpiece.

Arrival in Geneva

Ivan taking care of Markus.
After Markus was born on Feb 14, 2006, we had to wait for 6 weeks for Ana to recover, Markus to grow up sufficiently and get some shots until we moved beginning of April to Geneva….. It was an amazing trip to arrive in Europe with a few bags and the content of a number of bags I had brought a few weeks before in some trip to our new apartment in Thoiry. Ivan and Markus took it very well and Ivan loved to take care of his little brother.
Markus’ Arrival, continued
—- Valentine’s Day —-
When contractions get more intense Ana gets the epidural (around midnight). Afterwards we are ready for bed and I make my little bed and we get some good sleep. Around 3:04 the water breaks and things should intensify. Dilation is up to 6 cm now, still Ana is going slowely. Around 5:06 the doctor comes by and they decide to give Ana Pitocin to intensify the labor. Ana vomits her stomach empty in many small steps from now maybe induced by the Pitocin, or just because of the contractions.
Shortly before seven, Brenda our nurse comes by to say ‘bye bye’ because she is off duty at seven, Deborrah is next in line to take care of Ana. Doctor Frangel is on duty until 1pm.
Deborah gives Ana a refresh in the pushing, and all is quite clear. Markus could get on his way now 🙂 We are waiting. Ana is trying to get some rest. It is 7:26 now.
9:00 Cervix is fine now, we are at about 10cm dilation, ready to go, need to find the doctor, they are doing a scheduled C-section.
9:27 Dr. Weeks and Frangel are doing the C section but finishing up. Dr. Weeks is probably going to do the delivery.
9:35 Dr. Weeks arrives, two pushes and the baby is out…..
9:54 is the time of birth (remember Ivan was 0:54). He was blue when he came out head first and had the cord around his neck, pretty much like Ivan. Also the hair matched.
Markus' vitals are Weight: 9 pound 7 1/2 Size: 21 inches Head: 38 cm
He is a real big guy. Everything is fine with him. He has dark eyes, but lighter than Ivan and is a real sucker because he sucks on Mummy’s breasts about 30min after birth.
Meanwhile Ana pressed out the remainders and they come in one piece without further problem. All looks very healthy. Ana needs two little stiches because of small ruptures. The doctor is very content and thinks she has done very well. Stuff they make the movies of.
Markus’ Arrival
After a week during which Ana had every second night the feeling that we had to go to the doctor, tonight at 20:00 the contractions have become more violent and become more regular.
While Ivan is already fast asleep, ‘Grosi’ and I watch the famous Goldfinger with Gerd Froebe and Sean Connery. Ana takes a quick shower and continues monitoring the contractions….. Also Ana has a leak where some additional fluid is discharged…. at 21:10 Ana decides that it is time to call the hospital and leave for the delivery. Gerd Froebe has just taken down Fort Knox.
At 21:40 we are in the hospital and are lead to room 103 where we go through the usual reception questions and investigations. All is good and we are set. The baby’s heart beat is fine and Ana’s contractions are reasonable regular. Ana watches the news on CBS and relaxes a bit before we see whether really she is in labor. It looks like that yes and we change to a real delivery room 111.
After the usual checks and somewhat irrgular contractions (every 6 minutes) Ana and I try to get some rest. The delivery goes slowely but we are relaxed and Ana looks good.
