CPH – FRA – SXB – FRA – AHN – …

Finally in Athens!

After flying from Copenhagen to Frankfurt on Sunday, driving to Strasbourg with a rental car, spending two days at C.N.R.S. to look at CMOS sensors, driving by to Frankfurt by car and taking a flight from there to Athens, I know finally arrived at the Danish Institute in town.

To be a bit more precise, I went to Strasbourg to discuss a possible new project to get involved in and to have a look at CMOS detectors they build at C.N.R.S. that we wanna use in the experiment.

And now I am in Athens for about a week for a SMP (stable massive particles) sit-in!

On the plane to Athens I met Cédric a swiss pilot working for Aegean Airlines (greetz) and his lovely colleague who’s name I unfortunately forgot who recommended a few places in town that we might check out during the week …

Btw. the picture shows part of the Acropolis as seen from my balcony when I arrived in our apartment (about now)!

For those of you who can read German: the place shown in this article is exactly where I left the subway yesterday … quite a surprise!

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 …

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!
