LHC: dark matters

Continuing slow live blog of the “New Particle Physics at the LHC and Its Connection to Dark Matter” workshop at the Aspen Center for Physics. Series of short talks this morning: “A WIMPy Baryogenesis Miracle” by Yanou Cui, Lisa Randall, Brian Shuve (arXiv:1112.2704) interesting and possibly useful speculation on how electroweak scale WIMPs could couple…

“New Particle Physics at the LHC and Its Connection to Dark Matter” is the name of the current workshop at the Aspen Center for Physics running through Sep 9th. I’m hanging out for the first few days and the first presentation is on “what has the LHC Higgs done to supersymmetry”? So, basic point is…

Last talk of the LHC Shows the Way workshop, with the most provocative title. Entries in this post may or may not be mangled misrepresentations of stuff the speaker made up just to be provocative… Starting point: there is something at ~ 125 GeV and it is consistent with a boson, possibly a scalar, and…

LHC: composite Higgs

The LHC Shows the Way workshop is about to end, and the slow live blog limps along with a presentation on the composite Higgs. A model for having a light (~ 100 GeV ) scalar, is to have a composite Higgs instead of the alternative of either a true supersymmetric model or a light dilaton…

Back at the LHC Shows the Way workshop at the Aspen Center for Physics – more discussion of Higgs alternatives and peculiar branching ratios. No, the branching ratios for the different decay modes of the 125 GeV boson that is putatively the Higgs are not anomalous at a statistically significant level, but, they are off…

LHC: fake Higgs?

Back at the LHC Shows the Way workshop and slow live blogging of the discussion, with random asides for other stuff… Astronomy Magazine has a contest – win Brian May’s PhD thesis! – now separate post with added bonus question Today: fake Higgs – are there some new bosons which are not Higgs, but which…

LHC: dilating the Higgs

Continuing lazy live blog of the LHC Shows the Way workshop, with random interludes of alternative considerations, including the more esoteric aspects of German finance… Patio session (informal presentation of in-progress results on blackboard, outside) – didn’t catch speaker’s name, got here a couple of minutes late. Being reminded that Higgs is not the only…

LHC: Higgs overview

LHC Shows the Way workshop: general colloquium reviewing the LHC and the Higgs discovery. Kyle Cramner from NYU: “We discovered the goddamned particle” More slow live blog. Cute opening video of LHC construction. Factoid: kinetic energy of LHC beam is about that of a jumbo jet at cruise speed Starting point: Standard Model is ridiculously…

LHC: Higgs mass vs SUSY

The LHC Shows the Way workshop rolls on, looking at the implications of the Higgs at 125-126 GeV for supersymmetry. I live blog, slowly. Where are the sparticles. Coloured supersymmetric partners, the quark and gluon supersymmetric partners, must be massive – greater than ~ 1,000 GeV in some natural implementation of supersymmetry, natch, clever theorists…
