I am an experimental particle physicist working with the CMS experiment at CERN. In my spare time I play chess, abuse the piano, and aim my dobson telescope at faint galaxies.... Read More »

That did it, if only by an inch. Damn!

Two days ago, back from a 4-week vacation to Greece, I approached my faithful and precise scale with a clear, pre-determined thought in my mind: "If I am over 77.5 kilograms, I will start a strict diet to bring me back to below 72!".
This is a good year for summer meteor watching. The moon, just past new, will not interfere with observations of faint meteors. And the Perseid shower, originated from the dust left behind in the orbit of comet Swift-Tuttle, will produce a nice show. 

Perseids are a rather stable stream, and they produce a detectable rate of meteors from late July to late August, with peaks in the nights of August 11th and 12th, depending on the exact trajectory that the Earth takes while plunging in the dust-ridden area of the solar system. The rate is usually encoded in the acronym "ZHR", for zenith-hourly-rate. ZHR values of 100 to 150 are common for the two highest-rate nights.

But what exactly should you expect to see ?
CDF and DZERO, the two experiments at the Fermillab Tevatron collider, have studied top quark production since their own discovery of the heavy particle in 1995 (see here, here, and here for a three-post history of the top quark quest).

No, this is not about Physics. No, you are probably not interested. No, this blog is not only about science. I sometimes use it as -guess what- a log book, a diary. A habit I have learned five years ago, as I walked my first steps in the world of blogging, here. They (the organizers of "Quantum Diaries") wanted me to write about my life, and they got it. I learned a job, and some weird habits, like talking about my private life in public. It never caused much trouble, not nearly as much as just writing good articles on particle physics!
What picture should we draw of the quest for new phenomena after the presentation of a wealth of new results at the international conference on high-energy physics in Paris held last week ? I am speaking in particular of results coming from the experiments at the Tevatron and LHC, which are all studying hadron collisions in search for still unseen effects to both confirm (with the discovery of the Higgs boson) or break down (with the observation of Supersymmetry, new particles, extra dimensions, or still other effects) the present theoretical understanding of fundamental physics which the standard model provides us with.
