Higgs o non Higgs questo è il dilemma!!
Thursday, July 5, 2012
The hunt ended. Let's eat the prey.
The discovery of a "resonance" with a mass of ~125 GeV that may well be the Higgs boson, the missing piece in the Standard Model (SM) puzzle, has finally been announced by the ATLAS and CMS collaborations at CERN.
The (experimental) hunt started in 1989 at CERN with the Large Electron-Positron (LEP) collider and ended in the same place, but with the Large Hadron Collider (LHC), 23 years later.
For those of you interested in details, slides from the presentations given by representatives of the collaborations can be found at http://indico.cern.ch/conferenceDisplay.py?confId=197461
What follows may not be technically entirely correct but it is meant for people not working in particle physics to have an idea of how results are produced. Still a basic understanding of statistics is required.
For consistency, only results from ATLAS will be shown, however the reader must be aware that very similar plots have been released by CMS.

Domani siete tutti invitati, offre il CERN! Piatto del giorno...il bosone di Higgs!
Mancano ormai meno di 24 ore
all'attesissimo aggiornamento sullo stato della ricerca del bosone di
Higgs da parte degli esperimenti ATLAS e CMS, situati presso il Large
Hadron Collider (LHC) del CERN di Ginevra.
L'annuncio del seminario (il webcast per il pubblico sarà disponibile qui), avvenuto la
settimana scorsa da parte del direttore generale del CERN, Rolf
Heuer, e anticipato dai soliti “rumors” che accompagnano ormai
immancabilmente gli annunci scientifici più importanti (si veda il
caso dei neutrini superluminali), ha suscitato un interesse mediatico
notevole, con siti e giornali che hanno fatto e fanno tuttora a gara
per dare la notizia che il bosone di Higgs sia ormai stato trovato, affermando di avere come fonti scienziati interni alla collaborazione, che vogliono però sempre rimanere anonime.
