I am happy to report, with this rather unconventional blog posting, that I am getting married on...

Blogroll
The CDF collaboration sent to the preprint arxiv a new paper a few days ago. In it, they report on a measurement of the mass difference of top and anti-top quarks. The result would not be worth discussing in detail, if it did not show a 2-sigma discrepancy which might be the first hint of a CPT violation. So let me discuss it here.
My blogging output here is scarce this week, because I am spending my time at the NEUTEL 2011 conference in Venice. I am producing some posts summarizing the talks I hear at the conference, together with a few colleagues. Our blog there will be short-lived, but already collects about 1000 views a day, growing by the day. Here is a selection of recent posts you can find -I only list here those published today or yesterday:

The NEUTEL 2011 conference started today in Venice. Many experiments in neutrino physics will be reporting new results there, and the interest is of course high in the community. Along with a few vailant physicists from my university, I will be blogging form the site, trying to cover all the important new information as well as some other information in general. So please visit the NEUTEL11 blog to learn the latest news on neutrino physics... Already there is a report on a general overview of neutrino oscillations by Art McDonald, among with additional posts on HEP results.

... Not really.

What startled me most was that a colleague of mine at the University of Padova even sent a message to my departments' mailing list, saying that the new result is very important. But it clearly isn't! In fact, the exclusion at 95% CL in the range of Higgs boson masses that CDF and DZERO could put together from the analysis of additional data is almost exactly the same as the one that they published last Summer.

But maybe I should make a step back and explain the matter from the start, to let you judge by yourself the relevance of the new Tevatron bounds on the rate of Higgs boson production in proton-antiproton collisions.

CDF and DZERO are analyzing the proton-antiproton collisions at 2 TeV that the Tevatron collider is producing since 2001.

Neutrino phyisics may be boring, as Jester claims in a post today at the NEUTEL11 blog, or exciting, as many others are ready to testify. And since Jester talks about exciting new results ready to be submitted by the XENON100 collaboration, I would bet you will concur with the latter.

Readers of this blog know that I often discuss here the latest results of searches of Supersymmetric (SUSY) particles -nowadays furthered by the CDF and DZERO experiments at the Fermilab Tevatron collider, and by the ATLAS and CMS experiments at the CERN LHC.
