# Planck 2009

May 25 2009 | comment(s)

This morning the Planck 09 conference started at the Auditorium Altinate (see picture, right) in Padova. For a week, theorists and experimentalists will discuss hot topics in a variety of fields, from particle physics to cosmology, to string theory. A PDF file with the program is online.

# Tevatron Higgs Limits Strengthened By A New Theoretical Study

May 24 2009 | comment(s)

A new paper in the Arxiv attracted my attention this morning. It is titled "Perturbative QCD effects and the search for a $H \to WW \to l \nu l \nu$ signal at the Tevatron", and is authored by a set of quite distinguished theorists: C.Anastasiou, G.Dissertori, M.Grazzini, F.Stockli, and B.Webber.

# CDF Vs. DZERO: And The Winner Is...

May 21 2009 | comment(s)

Last Tuesday CDF announced their own discovery of the Omega_b baryon, a measurement which creates a controversy with the competing experiment at the Tevatron collider, DZERO. That is because DZERO had already claimed discovery for that particle, almost one year ago, and because the two measurements disagree wildly with each other. Just browse through my past few posts in this column and you will find all the information you need (how lazy can one be with links?).

"I seldom enjoy competition in real life. I find it fun only when I am up against somebody who takes things more seriously than I do."

# Live streaming of Omega B Discovery by CDF NOW!

May 19 2009 | comment(s)

In thirty minutes (4 PM Chicago time) a live streaming of the Omega_b discovery by CDF will be broadcast at this link: http://vms-db-srv.fnal.gov/fmi/xsl/VMS_Site_2/000Return/video/r_live.xsl

Please follow it if you are interested in particle physics - Pat Lukens, the main author of the analysis, and a very experienced and skilled physicist who has spent the better part of his life for the good of the CDF experiment, will be discussing this fantastic new analysis for all of us.
