Z Bosons From Heavy Ion Collisions

Z Bosons From Heavy Ion Collisions

Nov 19 2010 | comment(s)

A really interesting piece of news comes from the CERN laboratory today. The CMS experiment has detected a handful of Z boson decays in events featuring the collision between heavy ions, accelerated to energies of hundreds of GeV per nucleon.
A Geometric Theory Of Everything

A Geometric Theory Of Everything

Nov 18 2010 | comment(s)

Scientific American features an excellent article by Garrett Lisi and James Owen Weatherell, with title "A Geometric Theory of Everything". It is a rather clear explanation of the ideas behind the recent articles published by Lisi on the E8 group and how this exceptionally rich mathematical structure could embed the representation of all particles and forces of nature.
New Limits on the MSSM Higgs by DZERO

New Limits on the MSSM Higgs by DZERO

Nov 15 2010 | comment(s)

The DZERO collaboration  published a few days ago the results of their search for multi-b-quark signatures of Supersymmetry in a large dataset of proton-antiproton collisions at 1.96 TeV. The possible large coupling of higgs bosons to b-quarks makes searches with many b-quark-jets worth pursuing at the Tevatron.
Criticism Of A Paper In Support of Run III

Criticism Of A Paper In Support of Run III

Nov 11 2010 | comment(s)

The arxiv is featuring a new paper by Darien Wood, member and spokesperson of the DZERO experiment and a distinguished physicist with lots of experience in hadron collider physics. The paper is titled "The Physics Case for Extended Tevatron Running" and it is an explanation of the benefits that a Run III until 2014 will bring to our knowledge of high-energy physics.
The First ZZ Event In CMS!!

The First ZZ Event In CMS!!

As beautiful as they get, or even more so. It is hard to express the beauty of the event that the CMS collaboration published today. CMS, which stands for "compact muon solenoid", is one of the two main detectors operating at the CERN Large Hadron Collider (the other is ATLAS). The duo is seeking evidence for the Higgs boson, the only elementary particle predicted by the Standard Model that still awaits to be discovered.

Guest Post: Giorgio Chiarelli, Tevatron's Silver Wedding

Nov 05 2010 | comment(s)

Giorgio Chiarelli is a particle physicist. His research activity has been based largely at the Fermi laboratory near Chicago, US, at the CDF experiment. In 1994-96 he actively participated in the discovery of the top quark and in the first measurements of that particle's properties. Later, after directing the construction of a part of the new CDF detector, he moved its research interests toward the search for the Higgs boson. Currently he is a INFN research director in Pisa, where he leads the CDF-Pisa group. In the most recent years he dealt with problems connected with the communication of science.
