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.

From 1958 to 1970 Wladimiro Dorigo, my father, directed a political and cultural magazine called "Questitalia" ("This italy"), where emerging political issues were discussed, and the ongoing transformations of Italian society were dissected by a distinguished group of intellectuals. I own a copy of all the 150 issues of that publication, and every once in a while I pick one of them out of the lot at random, and learn what Italy was 40 or 50 years ago.
