The Plot Of The Week – SUSY After The Higgs Discovery

By Tommaso Dorigo | January 15th 2013 04:31 AM

I may have been unattentive to recent papers on Supersymmetry, but I got the impression that during the last few months the majority of SUSY phenomenologists have been keen on speculating on the few apparently non-standard features of the recently discovered Higgs boson, as published last June (such as the alleged copious decay of photon pairs, or the dearth of decays to tau lepton pairs or b-quark pairs – note: all are mostly back to what the standard model predicts, after the analysis of more data following the discovery announcements), but rather improductive on the front of taking the new signal as a pivot point for new global fits.

The matter is not trivial, although quite important. Inserting the new information in global fits is not trivial because if you want to do things correctly you need to take in account a dozen different rate and limit measurements (which are often moving targets given the pace of new results coming out of LHC and the Tevatron) and reconcile them with the predicted branching fractions that a quintet of non-standard model Higgs bosons may exhibit; with the added trouble that in case more than a single state lies close to 125 GeV they may have been unresolved by the current LHC data, and their branching fractions and relative rates need to be accounted together.
