Searching for Higgs bosons in association with top quark pairs in the H0 -> bb decay mode [online]

Drollinger, Volker; Mueller, Thomas; Denegri, D.


Search for the Higgs Boson is one of the prime goals of the LHC.
Higgs bosons lighter than 130 GeV/c2 decay mainly to a b­quark
pair. While the detection of a directly produced Higgs boson in
the bb channel is impossible because of the huge QCD
background, the channel ttH0 --> l±vqqbbbb is very promising in
the Standard Model and the MSSM.
We discuss an event reconstruction and selection method based on
likelihood functions. The CMS detector response is performed
with parametrisations obtained from detailed simulations.
Various physics and detector performance scenarios are
investigated and the results are presented. It turns out that
excellent b­tagging performance and good mass resolution are
essential for this channel.
