After quite some time we finally managed to finish an ATLAS note on some of the stuff I did during my last longer stays at CERN in 08/09: “A Summary of Thermal Measurements from the Pixel Commissioning Program” (ATL-INDET-INT-2011-003) has been approved today!

Working in Rome
Yesterday I came back from a short visit to Rome, joining the ATLAS LLP workshop to get the 2011 analyses and myself started.
Besides the very nice workshop, we had a good time doing some New York Times recommended dining at Felice a Testaccio and Da Franco Ar Vicoletto and some sight seeing in Rome at above 25 degrees …
Just for the fact book: the meeting took place at Sapienza, being the largest university in Europe with about 147.000 students.
Where it all began …
After a stunning decent to Geneva airport, looking over the snowcapped mountains, a Big Bang Theory marathon and watching Armadillo yesterday, I just came back to the place where everything started at CERN: the NBI office 32 S-A10.
Dr. Mehlhase

Finally … I got my diploma today!
So I am officially Dr. Mehlhase now :)
Woooooohoooo
W-elcome at the LHC
ATLAS just issues the latest release of its e-news, officially announcing the first W boson candidate events in the LHC … which of course reminds me of my nice little master thesis on the W mass measurement at ATLAS.
Below are illustrations of the two candidates: one W decaying into an electron (left) and one into a muon (right), of course both accompanied by the according neutrino, represented by missing energy (ETmiss) in the event.
