Blogroll
Today's guess of the plot will be very poor of comments on my side, for reasons I will disclose in due time. Also, it is unfortunately a rather expert-only one, since it represents something that experts will surely recognize for its generalities, while only the details will probably remain mysterious to them.

I will be glad to read your guesses in the comments thread, which I hope will be plenty and insightful. Hopefully in a few days I will disclose what the plot represents.

UPDATE: In place of the plot, events force me to put in its place something else, for just a few hours. See below - the change is not dramatic, but what is added is probably giving a stronger hint than what is taken off.
Ettore Majorana was maybe the most brilliant student of Enrico Fermi, and an outstanding physicist. He disappeared on March 25th 1938 at the age of 32 years, under mysterious circumstances and leaving no trace behind. The hypothesis that he committed suicide appears weak in the face of his withdrawing a conspicuous amount of money from his bank on the eve of his disappearance -he had a rational mind and such an action would have made little sense. Other hypotheses include an escape to Argentina, and even a collaboration with the third reich in Germany, where he had previously worked -Majorana had expressed anti-jew ideas in the past.
I see people around very, very interested in what the CDF experiment has recently unearthed. I am talking, of course, of the jet-jet resonance candidate that they observe in their W+jets sample. A recent update of the previous result shows that the significance of the bump is just short of the coveted five-sigma: that is to say, for non-insiders, there is now a chance in two or three millions that the effect is due to a statistical fluke.
I Will Vote

I Will Vote

Democracy should never be given for granted. So if you are given a chance to cast a vote, you should not overlook the fact that voting is both your duty toward your country, and a right you need to exercise if you don't want to lose it.

In Italy on June 12th and 13th citizens are called to vote directly to abolish a couple of laws that the current government insisted on forcing upon us. I will not spend a word on the laws themselves, since that is not the point of this short post. Rather, I want to explain the importance of going to vote, and why I hope that Italian readers of this blog will do it.
Summer conferences are just around the corner, and the LHC experiments are putting together O(1 fb) samples as we speak (in another post I will report on the progress of data collection at CMS, which has already collected over 650 inverse picobarns of useful data). It seems that this is a good time to make the point of where we stand with Higgs boson searches.

I am speaking, of course, of the Standard Model (C) Higgs boson, the only one which exists (maybe). Fancier concoctions, predicting five, eleven, or exp(pi) new scalars will be reviewed another day when I am under drugs.

WTF. A pleasant, unexpected surprise awaited me in the CMS Times, the online periodical which reports on the status of the CMS experiment at the Large Hadron Collider, the research activities, the people participating in the experiment.
