Matt Strassler again: ways that reality might depart from the most common three assumptions about the phenomenology of supersymmetry. (For very unorthodox supersymmetry, see here.)

More Higgs
Matt Strassler, reporting on a Mumbai conference: "Most interesting result from Tevatron: both CDF and D0 see an excess of events consistent with a supersymmetric Higgs particle in the mass range 120-150 GeV, in a production mechanism that is absent in the Standard Model. (Experts: this is b-quark plus Higgs, where Higgs decays to b-quark and b-antiquark) However this is a tough measurement and it is hard to know whether to trust this… and the excesses are not that large. (And Higgs decay to taus is not observed with a b.)"

Higgs
Hello world, it's been a while, hasn't it? This blog went into hibernation once it began to look like there was no phenomenon to explain, just a glitch in the modeling of background events. But I will now rouse it from its slumbers to report a few things.
At the moment, the search for the Higgs boson is the center of attention. Lubos Motl likes the idea of one Higgs at 115 GeV and another at 144 GeV, as indicative of supersymmetry. But meanwhile I shall report a paper which instead seeks to explain two such Higgses in terms of a composite model; and another which explains the Tevatron data in terms of a two-Higgs model. But first let us see what the LHC says after a few more months.
