Tsunami Expected In Sumatra Now

Apr 11 2012 | comment(s)

A powerful earthquake has struck an hour ago, at 8.30UT, very close to the place where a similar event occurred on December 26th 2004. The earthquake has an estimated magnitude of 8.7 and occurred at a depth of 33km, according to NOAA. The map below shows the location of the event and the potentially affected areas.

LHC @ 8 TeV: First Week Of 2012 Run

Apr 10 2012 | comment(s)

Last week the Large Hadron Collider has started producing collisions at the record high 8-TeV centre-of-mass energy to the ATLAS and CMS detectors.

In the course of the first week of run almost 200 inverse picobarns have been delivered to CMS, which is absolutely satisfactory.

The integrated luminosity versus time is shown below.

And here is the peak instantaneous luminosity reached during these first few days of running:

(NB: I believe the above figure lacks a "s^-1" units).

A Stroll in the park with Bente

As I had announced in my blog, I spent four days in Oslo before Easter, visiting museums with my kids and my fiancee, and enjoying the place -new to all of us.

Off to Oslo

Apr 03 2012 | comment(s)

Today I am leaving to Norway, for a visit of few days. If you happen to have suggestions for things to see and do there, please drop me a line in the comments thread below; I will be traveling with my son Filippo (13 yo) and daughter Ilaria (9), so avoid advising me on night clubs or wine bars; museums and entertainment are more like what I am likely to be interested in.

Also, if you live nearby and are (presumably) interested in particle physics, I will be happy to have a drink together. I'll tell you the news from the LHC experiments, you can in return give me information about the place. My phone number is 0039-3468671707.

Unmistakable Gluino Signal In ATLAS !!

Apr 01 2012 | comment(s)

And after all I said about Supersymmetry being an invention, I fear I now have to eat it all with my hat to boot ! The ATLAS Collaboration has just released results of a very striking search for gluinos, which increases the sensitivity over past analyses by employing a much improved and cleaned-up version of missing transverse energy along with a higher-resolution version of the effective mass variable used in the past, and has found a first strong evidence for Supersymmetric decays !!

Superluminal Neutrinos: Opera Spokesperson Resigns

Mar 30 2012 | comment(s)

Antonio Ereditato (left), spokesperson of the Opera collaboration, announced today he stepped down. He is no longer leading the Opera experiment.

The Opera experiment last September made headlines around the world with their announcement that neutrinos sent from the CERN laboratories to the Gran Sasso cavern appeared to be moving at superluminal speed.
