Light minimal supersymmetric standard model Higgs boson scenario and its test at hadron colliders

Belyaev, Alexander, Cao, Qing-Hong, Nomura, Daisuke, Tobe, Kazuhiro and Yuan, C.-P. (2008) Light minimal supersymmetric standard model Higgs boson scenario and its test at hadron colliders Physical Review Letters, 100, (6), 061801-[4pp]. (doi:10.1103/PhysRevLett.100.061801).

Record type: Article


We show that, in the minimal supersymmetric standard model, the possibility for the lightest CP-even Higgs boson to be lighter than Z boson (as low as about 60 GeV) is, contrary to the usual belief, not yet excluded by the CERN LEP2 Higgs search nor any direct searches for supersymmetric particles at high energy colliders.

The characteristic of the light Higgs boson scenario (LHS) is that the ZZh coupling and the decay branching ratio Br(h/A?bb? ) are simultaneously suppressed as a result of generic supersymmetric loop corrections. Consequently, the W±H?h coupling has to be large due to the sum rule of Higgs couplings to weak gauge bosons. We discuss the potential of the Fermilab Tevatron and B factories to test the LHS, and show that the associated neutral and charged Higgs boson production process, pp?H±h(A), can completely probe the LHS at the CERN Large Hadron Collider.
