A general review of the latest results about single and double vector boson production in the multipurpose experiments at LHC (ATLAS and CMS) and at Tevatron (CDF and D0) will be presented. The review will focus on boson production, while a more deta
iled report about W and Z properties can be found elsewhere. Only leptonic decays into electrons and muons will be considered.
We present measurements of the masses and widths of four bottom baryon resonances, Sigma_b(*)+-, reconstructed in the Lambda_b pi+- hadron decay modes. The isospin mass splittings for the Sigma_b and Sigma_b* multiplets are extracted as well. The ana
lysis is based on a data sample corresponding to an integrated luminosity of 6 fb^-1 .
