"Non ho mai chiesto di occuparmi di mafia. Ci sono entrato per caso. E poi ci sono rimasto per un problema morale. La gente mi moriva attorno"

(I never asked to work on mafia. I got to do it by chance. And then I continued because of a moral issue. People around me kept dying.)

Two Standard Deviations From Tevatron Results Of Bs Mesons

Two Standard Deviations From Tevatron Results Of Bs Mesons

Jul 26 2009 | comment(s)

One year ago, a paper by a distinguished group of theorists announced first evidence of new physics from measurements of the properties of B_s mesons performed at the Tevatron by the CDF and DZERO experiments. They had combined all the available information, obtaining a result which disagreed with the Standard Model (SM) prediction by more than three standard deviations.

The happy nights of Italy's Premier Silvio Berlusconi, now documented in hot recordings taken by Escort Patrizia D'Addario, have by now circled the free world (in Italy they are only available to readers of a couple of newspapers allegedly "hostile to the government", Repubblica and L'Espresso).

Will The Standard Model Die By The Hands Of Its Dearest Child ?

A new paper on the ArXiV caught my attention this evening for several reasons. First of all, because two of its five authors (J.Ellis, J.R.Espinosa, G.F.Giudice, A.Hoecker, and A.Riotto) are (or have been) my colleagues in Padova University; second, because the title is quite catchy; third, because indeed the results it presents are valuable food for thought.

"Other people's data ntuples are a bit like their genitals. You may occasionally be allowed to play with them, but you should not expect to be granted unhindered access."

B-Quark Jets: Keys To New Discoveries

B-Quark Jets: Keys To New Discoveries

Jul 22 2009 | comment(s)

In this two-parts article I wish to describe in some detail, but still at an elementary level, the characteristics of one of the most important probes of the physics of subnuclear collisions at today's particle physics experiments: jets of hadrons originated from energetic bottom quarks, or more familiarly, b-jets. By posting a dedicated article on b-jets, I hope I will be able to describe in more detail elsewhere other physics topics, such as Higgs boson decays or top quark signatures, without being hampered by having to introduce the phenomenology and detection of b-jets from scratch every time.
