Blogroll
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.

Upon expressing the Higgs potential in terms of the field H0, we find



The first term in V is a constant energy density which can be interpreted as a contribution to the vacuum energy,


I just became aware of a letter that is being sent to a couple of US Senators by a large and illustrious collection of scientists, and I decided to put my signature below it. The letter is clear and I will not comment it here - suffices to just paste it here.

By the way, I do not think that more signatures are necessary to it, but if you agree with the contents and wish to participate your support, please do so by adding your name below, in the comments thread. It will just take you thirty seconds of your valuable time, but it might have an impact here too.
