### D0: new limits on fermionic superpartner masses

D0, a consensus of 500 scientists listed on the first two pages ;-), decided that inside 1.1 inverse femtobarn of data, there are no SUSY femions. At 95% confidence level, the lightest neutralino is above 125 GeV and the lightest chargino is above 229 GeV. As expected, the MSSM Higgs Conway bump around 160 GeV has disappeared, too, debunking not-too-careful rumors. Nevertheless, an introduction to MSSM and the Higgs is included in the article below.

CDF, the other detector team at Fermilab, has measured the width of the W boson as 2.032 GeV, in a good agreement with the Standard Model.

ILC, the International Linear Collider, has created a slick brochure (passport) promoting their future project:
