String theorists betting against SUSY
This post contains second-hand information, but I place it here anyways because a blog is also a record of things. So, I read with interest on Peter Woit’s blog a summary of the latest paper posted on...

New zoom in on the Higgs mass from Summer 2008 Tevatron results!
Many thanks to Sven Heinemeyer, who provided me this morning with a fresh update of the traditional plot summarizing the status of Standard Model measurements of top quark and W boson masses, their...

Predictions for SUSY particle masses!
Dear reader, if you are not a particle physicist you might find this post rather obscure. I apologize to you in that case, and I rather prefer to direct you to some easier discussion of Supersymmetry...

Ridiculous branching fractions nailed
B hadrons are fascinating bodies. They are bound states of a bottom quark and lighter ones, and due to the smallness of a parameter called , the element of the Cabibbo-Kobayashi-Maskawa mixing matrix,...

Arkani-Hamed: “Dark Forces, Smoking Guns, and Lepton Jets at the LHC”
As we’ve been waiting for the LHC to turn on and turn the world upside down, some interesting data has been coming out of astrophysics, and a lot of striking new signals could show up. This motivates...

Some posts you might have missed in 2008
To start 2009 with a tidy desk, I wish to put some order in the posts about particle physics I wrote in 2008. By collecting a few links here, I save from oblivion the most meaningful of them -or at...

No CHAMPS in CDF data
A recent search for long-lived charged massive particles in CDF data has found no signal in 1.0 inverse femtobarns of proton-antiproton collisions produced by the Tevatron collider at Fermilab. Most...
