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 …

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.

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!

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.
