If you have a minute to spend watching something really cool, why not having a look at the completion of the installment of GEM detectors in the CMS experiment at the CERN Large Hadron Collider, ***RIGHT NOW*** (6PM CEST Oct 24th) ?
The most recent preprint in the ArXiv this evening is an APPEC report on the neutrinoless double beta decay
. This is the thick result of a survey of the state of the art in the search for a very (very) rare subnuclear process, which can shed light on the nature of the mass hierarchy of neutrinos. Oh, and, APPEC stands for "AstroParticle Physics European Consortium", in case you wondered.
This week's Plot relates to the search of rare decays of the Higgs boson, through the analysis of the large amounts of proton-proton collision data produced by the Large Hadron Collider (LHC), CERN's marvelous 27km particle accelerator. The ATLAS collaboration, which is one of the four main scientific equipes looking at LHC collisions, produced an improved bound on the rate at which Higgs bosons may decay to electron-positron pairs (which they are expected to do, although very rarely, in the Standard Model, SM) and to electron-muon pairs (which are forbidden in the SM).
A few weeks ago, in an article where I discussed some new ideas for fundamental physics research
, I briefly touched on an incident in which Paul Frampton, a well-known theoretical physicist, got involved in 2011. The paragraph in question read:
Sometimes browsing the Cornell ArXiv results in very interesting reading. It is the case with the preprint I got to read today, "DAMA/LIBRA annual modulation and Axion Quark Nugget Dark Matter Model", by Ariel Zhitnitsky.
This article puts forth a bold speculative claim, which I found exciting for a variety of reasons. As is the case with bold speculative claims, the odds that they turn out to describe reality is maybe small, but their entertainment value is large. So what is this about?
On August 20, in occasion of the "5th International Workshop on Nucleon Structure at Large Bjorken x
", organized at the Orthodox Academy of Crete, I had the pleasure to accompany at the piano my wife, the soprano Kalliopi Petrou, for a concert offered to the participants to the workshop by the organizers.
