# Rudiments Of The Method Of Maximum Likelihood

Jul 29 2009 | comment(s)

Besides the usual share of random readers who google something and get directed here by mere chance (to be read: by the sheer amount of valuable information I have posted here), this blog is read by an interesting mix of particle physicists, students, experts in other fields of Physics, and Science amateurs -plus a small number of science reporters looking for news.

Of course I love each and every one of my faithful readers like good teachers love their pupils, but among the varied crowd, the readers which I am most happy to host here are students and amateurs, because they provide me with true motivation for spending my time writing popularization articles. Without them, many of my posts would lose their meaning.

"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

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 ?

Jul 23 2009 | comment(s)

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.
