Clouds made with particle beams: atmosphere and particle physics meet in the lab!
My new publication of the month might actually something I might get into touch with sooner or later …

Updates on the unknown
CDF (one of the collider experiments at Fermilab) has just presented another update on their April paper on the invariant mass distribution of jet pairs produced in association with a W boson. In the latter one they discussed an excess in the 120-160 GeV/c^2 mass range with a significance of 3.2 sigma. They do not dare to give an exact number but claim to be closer to 5 sigma now!?
Unfortunately, though announced several times, the D0 collaboration has not published any similar analysis yet…
Also the result is not backed by all members of the collaboration …
so it remains exciting and CDF still owes us a good explanation …
Chocolate chicken stew and lots of cake
Even at lunch in the NBI canteen I learned something today … chocolate chicken stew is actually quite nice. Yes you read right, we had chocolate chicken stew in the institute canteen today!
After several year of suffering from and boycotting the DESY canteen in Zeuthen I rediscovered canteen food here Copenhagen. It’s no haute cuisine but it’s fairly good food, which is for Danish standards and compared to DESY not too expensive …
Besides that we had “cake day” at the institute as well … meaning, the whole institute met under the nice magnolia tree in front of our building and ate cake that various people brought … brownies, chocolate, blueberry and marzipan cake … had the all … hmmm
New world record
Tonight the LHC continued the 2011 data taking with a new world record in luminosity of 4.67 x 1032cm-2s-1, breaking the previous record of the Tevatron of 4.0247 x 1032cm-2s-1.
Finally done!
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!
