New Tight SUSY Exclusion From ATLAS

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 ...

My Four Sketches Put To Good Use

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 vi ...

CPT and MINOS

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 ...

Japanese Researchers Use Booze For Superconductivity

Booze has likely inspired many an action in researchers but any actual science effect was second order.   No more.   Scientists from the National Institute for Materials Science in Japan found that immersing pellets of an iron-based compound in heated alco ...

Mysterious Symmetry Between Destruction And Growth

Superfluid liquid Helium is shot under very high pressure out of a tiny nozzle and into vacuum. Outside in front of the nozzle, the excess pressure bursts the liquid apart violently into a myriad of fragments. A cloud of ultra small droplets comes into ex ...

The Say Of The Week

Upon expressing the Higgs potential in terms of the field H0, we find The first term in V is a constant energy density which can be interpreted as a contribution to the vacuum energy, ...

More SUSY Forecasts From Recent ATLAS Results

Readers of this blog know that I often discuss here the latest results of searches of Supersymmetric (SUSY) particles-nowadays furthered by the CDF and DZERO experiments at the Fermilab Tevatron collider, and by the ATLAS and CMS experiments at the CERN L ...

The Ultra Conservative Fringe

I define the fringe as anyone trying to make a contribution to a field where they are not employed or do not have a degree in the subject.  I happen to be a fringe physicist because my degrees from MIT were in Biology and Chemical Engineering.  My current ...

Links You Should Keep An Eye On

Neutrino phyisics may be boring, as Jester claims in a post today at the NEUTEL11 blog, or exciting, as many others are ready to testify. And since Jester talks about exciting new results ready to be submitted by the XENON100 collaboration, I would bet you ...

New Higgs Limits From The Tevatron... New?

... Not really. What startled me most was that a colleague of mine at the University of Padova even sent a message to my departments' mailing list, saying that the new result is very important. But it clearly isn't! In fact, the exclusion at 95% ...
