Recent Results Of CMS

Jun 14 2012 | comment(s)

Two days ago I discussed at ICFP 2012 the most recent results of the CMS experiment at the CERN Large Hadron Collider. In the allotted time of my talk I could only cover few analyses, and I obviously chose some of the most interesting ones, so that was already a summary. Here I am bringing the information collapse one step further, by giving a itemized summary of some of the points I made, just in case you are interested. If you want to, you can also download the original slides of my talk from here (but be careful, it's a 8Mb file).

The International Conference on New Frontiers in Physics (ICFP) 2012 started today with a rich program of experimental and theory talks. I should be swimming in the Cretan sea in front of the nice conference venue (which is 40 meters away from the water), but my sense of duty forces me to give you some impressions of the presentations I heard.

The island of Crete, in the middle of the Mediterranean sea, is home to ICFP 2012, a conference in high-energy physics. I arrived yesterday night and this morning I woke up with a gorgeous view of the sun rising over a blue sea.




(The picture shows a beach not far from here, which I'll visit on Wednesday. It is called "Balos beach" and it is a wonderful place).

New CERN Results On Rare B Decays: A Tombstone To SUSY ?

The CERN average of searches for rare B decays to muon pairs has been shown yesterday in a talk given by Mitesh Patel at the "Physics at the LHC" conference, which is being held in Vancouver (BC) this week. And the results are not very encouraging for supporters of Supersymmetry: the data is compatible with a Standard Model signal, but there is almost no space left for additional contributions due to the exchange of virtual SUSY particles in the loops producing the decays.

The winner picture of the Venus transit must be the one below, whose original version can be found here. Thanks Bente Lilya Bye for posting the link on her Facebook page!



The picture was taken by Hinode, a joint JAXA-NASA mission to study the Sun's magnetism in and around sunspots.

Well, so as predicted Venus passed over the disk of our Sun yesterday (this morning, if you live in Europe), and it produced quite a show, as many pictures and videos available around testify. To make the view more pleasing, our Sun was showing a discrete amount of solar spots, betraying the fact that we are approaching Solar Max (there is a 11-year cycle of solar activity, which manifests itself visually with black spots appearing on the disk, and on the Earth with auroras and electromagnetic disturbances).

In case you want a quick link to a nice slideshow showing Venus crossing the Sun's disk in a set of some thirty images, please visit this flicker site.
