Physics

Just a very short post here to mention Marni Dee Sheppeard's guest post in the brand new NEUTEL blog, the blog of the Neutrino Telescopes 2011 conference, which will be held in Venice from March 15th to March 18th, in the beautiful setting of Palazzo Franchetti, on the Grand Canal. Marni discusses the connection between MINOS results and CPT violation.
In a recent post I mentioned here that for the first of two feature articles I wrote for Physics World, and which just appeared in this month's issue (the first piece is actually available online here), I had hand-drawn four sketches that described visually the four main steps of a data analysis looking for new physics.
The results of a new Supersymmetry search have been released a few days ago by the ATLAS collaboration. They come from an analysis of events with large missing transverse energy and jets -the most classical signature of SUSY at hadron colliders, as well as the most sensitive one in a wide range of the complicated space of SUSY parameters.
From March 15th to March 18th I will be following the NEUTEL 11 conference, which conveniently (for yours truly!) takes place in Venice, in the magnificent setting of Palazzo Franchetti (see picture below).

NEUTEL (first bulletin here) deals with results in particle physics and astrophysics produced by, or in connection to, neutrino telescope experiments; the most recent advances in the theory of neutrinos, astrophysics, and cosmology will also be discussed by eminent theorists.

Every once in a while we are told that Schrödinger’s cat is now proven. One incarnation of the ‘Finally Proven!!!’ of macroscopic quantum superposition was hailed as one of the 10 breakthroughs, the breakthrough of the year 2010. By Science about an article in Nature [1], no less!

Just appeared on Physics World online: the first of my two feature articles on LHC physics in 2011, which are being published in this month's issue.
Modern cosmology believes that for the universe to behave as it does, the mass-energy of the universe must be dominated by dark matter and dark energy, though there is no direct evidence for the existence of these invisible components.    Alternate, though unpopular, possibilities are that the current theory of gravity does not suffice to describe the dynamics of cosmic systems.

Quantum physics and Einstein’s relativity theory, in theory as well as experiment, are extremely concerned with light and its photons. Why should fundamental science be obsessed with something so feeble? Well, it could not be any other way! Science is about what we can (experimentally) observe. As physics advances, it must be expected to be more and more concerned about the most reliable way to measure. It must investigate observation as such.

Ben Allanach is a professor of theoretical physics at the University of Cambridge. Before that he was a post-doc at LAPP (Annecy, France), CERN (Geneva, Switzerland), Cambridge (UK) and the Rutherford Appleton Laboratory (UK). I noticed a recent article of his in the arxiv, and asked him to report on it here, given the interest that the recent LHC results have stirred in the community. He graciously agreed.... So let us hear it from him! 

Blimey, I'm tired. I'm also elated and excited and grateful to my lovely girlfriend, who's not only putting up with my long hours, distracted head and general ensuing grumpiness, she's even looking after me.

Both the CMS and ATLAS collaborations have already started to exclude meaningful regions of the parameter space of Supersymmetric models with the data they collected in 2010. And Physics World is on the news today with a online article by Kathy Mc Alpine, the famous rapper physicist who wrote the lirics and interpreted one of the biggest Youtube hits in the category of science popularization. If you have not watched it yet, please rush to do so now. Six million people (and counting) have done so before you already.
