A Book By Guido Tonelli

Yesterday I read with interest and curiosity some pages of a book on the search and discovery of...

Are There Two Higgses ? No, And I Won Another Bet!

I am an experimental particle physicist working with the CMS experiment at CERN. In my spare time I play chess, abuse the piano, and aim my dobson telescope at faint galaxies.... Read More »


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.

Just a very short post here to mention Marni Dee Sheppeard's guest post in the brand new NEUTEL blog, the blog of the Neutrino Telescopes 2011 conference, which will be held in Venice from March 15th to March 18th, in the beautiful setting of Palazzo Franchetti, on the Grand Canal. Marni discusses the connection between MINOS results and CPT violation.
In a recent post I mentioned here that for the first of two feature articles I wrote for Physics World, and which just appeared in this month's issue (the first piece is actually available online here), I had hand-drawn four sketches that described visually the four main steps of a data analysis looking for new physics.
The results of a new Supersymmetry search have been released a few days ago by the ATLAS collaboration. They come from an analysis of events with large missing transverse energy and jets -the most classical signature of SUSY at hadron colliders, as well as the most sensitive one in a wide range of the complicated space of SUSY parameters.
