First Dimuon Decays Of B_s Mesons Observed By CDF ?

First Dimuon Decays Of B_s Mesons Observed By CDF ?

Jul 13 2011 | comment(s)

I was waiting for the announcement in the Fermilab seminar of next Friday, but apparently despite I am still a member I am not well enough informed of what happens inside CDF, the experiment at the Tevatron proton-antiproton collider of Fermilab. So the paper is now public, and you can read the news in the Cornell arxiv: CDF sees an excess of muon pairs which is compatible with originating from the decay of B_s mesons.
New CMS Constraints On SUSY

New CMS Constraints On SUSY

While other sources (voluntarily not linked here, to avoid pissing off my collaborators) choose to be "on the news" these days, with a brand new exclusion plot of the Higgs boson obtained using almost one full inverse femtobarn of collisions which is not yet public but was made accessible by mistake on a Fermilab site, I will meekly point you out today to another result, which is by all means public and freely reproducible here (no reproach to Phil intended here -he acted in good faith and the fault is not his).
Guess The Plot 5

Guess The Plot 5

Jul 07 2011 | comment(s)

This instance of my "guess the plot" contest will be hopefully raising fewer controversies than the former one. You are asked to explain what the figure represents, possibly guessing the units on the x and y axes.

More advanced readers may know at a glance what this plot is and where it comes from. To them, I ask the favour to wait one day (to not spoil the game to the less knowledgeable users) before trying a harder challenge: by heart, explain the meaning of every single distribution shown -e.g. provide the correct key of the masked legend on the right.
DZERO Charge Asymmetry Grows To 3.9 Standard Deviations

DZERO Charge Asymmetry Grows To 3.9 Standard Deviations

Jul 04 2011 | comment(s)

The DZERO collaboration has just produced an update of their analysis of the dimuon charge asymmetry using 9.0 inverse femtobarns of proton-antiproton collisions. The new result confirms the previously reported effect, raising the discrepancy with the Standard Model prediction to over four standard deviations.

A New Blog Out There!

A New Blog Out There!

Jun 28 2011 | comment(s)

I am quite happy today to announce here that there is a new blog to visit, and to bookmark!, for those among you who are interested to know what does a PhD in physics do after he or she graduates. In particular, as is explained in the subtitle, the question that the blog addresses are:

What are the sectors of employment for a physics graduate? How do you get a job in keeping with your studies/interests?
