Susy Enhancement of Heavy Higgs Production

Abstract

We study the cross-section of heavy Higgs production at the LHC within the framework of the Constrained MSSM. It is not only enhanced by tan 2 β but sometimes is also enhanced by the squark contribution. First, we consider the universal scenario within mSUGRA and find out that to get the desired enhancement one needs large negative values of A 0 , which seems to be incompatible with the b → sγ decay rate. To improve the situation, we release the unification requirement in the Higgs sector. Then it becomes possible to satisfy all requirements simultaneously and enhance the squark contribution. The latter can gain a factor of several units increasing the overall cross-section which, however, is still smaller than the cross-section of the associated Hbb production. We consider also some other consequences of the chosen benchmark point.

Beyond-MSSM Higgs sector(s)

“…The FlavorKit interface [114] allows to calculate many flavor observables in BMSSM models via the combination FeynArts/FormCalc-SARAH-SPheno. Alternatively, one can also use FeynArts & FormCalc either stand-alone or coupled to Peng4BSM [115].…”
