Physics

Of the dozens of new physics models which are currently on the market of Standard Model extensions and plug-ins, the ones hypothesizing the existence of additional dimensions of space-time beyond the…

A new result by the CMS collaboration has been produced today on top quark physics. For those of you who only get triggered by the search of new particles or new forces, the study of "yesterday's…

You have seen it already two months ago, but those were "preliminary" results. Now both CMS and ATLAS have produced full-fledged documents (CMS here, ATLAS here) describing their respective…

I spent the week seeing if I could give the good old college try and find a "way that worked" for the gauge games I have been playing. Nothing panned out. Bummer, I had a blog to write. While…

Happy 2012 ! I had not been writing any post in this blog since last October.  Furthermore, my first article was not devoted to my own work of this period discussing the OPERA result on a…

We are all familiar with velocities. Velocities tell us how positions change with time. Velocities can not be assigned to individual objects, as they describe a relation between pairs of objects. We…

Last week I spent a few interesting days in the pleasant winter setting of Engelberg, a mountain location in the Swiss alps. There I attended the CHIPP 2012 winter school, an event organized by…

First I will play the old gauge symmetry game repeated everywhere for EM. I will then teach that old dog a new trick that ends up with the same bone. I will then struggle a little over the lingo to…

The CMS Collaboration has just released the results of a deep study of their sample of lead-lead collisions, produced at a center-of-mass energy of 2.76 TeV per nucleon by the Large Hadron Collider.…

The CHIPP 2012 winter school of particle physics is over, and so is the 50th winter meeting on nuclear physics. The two events had three things in common: they were both held in renowned locations…
