After the Pandora vase of Berlusconi's private life got opened, there are news trickling out from it every day. In the last few days we learned that the parties thrown by the Italian premier in his billionaire villa in Sardinia, or at his residence in Rome, Palazzo Grazioli, included scores of young women that were not there by chance, but allegedly with the purpose of entertaining -offering sex- the male participants. There is, in fact, a judiciary action going on, which is trying to ascertain the declarations of a few women who participated to those parties, and who declare they were offered money.

Ok, this is an old story and probably all of you have seen the footage already - but after seeing the video myself, I cannot avoid posting it in my blog too. The recorded ending of a moving story of love between a lion and two young men is still all the rage on YouTube several months after being posted, and if you have not seen it yet, here is your chance to get even.
Energy Calibration Of B-Jets: Part II

Energy Calibration Of B-Jets: Part II

Jun 16 2009 | comment(s)

Below I offer a preview of the slides I will show tomorrow at an invited seminar on the rather technical topic of  "The b-jet energy calibration with Z-->bb decays", which I have come to CERN to give at a meeting of the LHCb collaboration. As I mentioned already in the first part of this two-part article, the topic is rather technical, and I do not expect a large audience -but I will nonetheless make an attempt at explaining the meaning of the slides pasted below. Then, of course, I am available to provide some additional light on any specific issue among those dealt below which you may want to understand more about.

Tomorrow I am traveling to CERN, where I have been invited to give a seminar at a meeting of the LHCb experiment. My talk will discuss the issue of the energy calibration of b-quark jets, a topic to which I have devoted a good part of my research time for the last thirteen years. The talk will of course be centred on the explanation of the analysis Julien Donini and I, together with a few colleagues, performed in CDF a few years ago, the search for Z boson decays to b-quark jet pairs.

Today I visited the 53rd international art exposition at the Biennale di Venezia, which this year is titled "Fare Mondi" (making worlds). I am posting below a few pictures I took of the installations I saw there, for those of you who are not insensitive to contemporary arts. But before I do, let me add a personal note.
