A scalar particle has been discovered at the Large
Hadron Collider (LHC), but it is not yet known if this
particle corresponds to the Higgs boson of the Standard
Model or if it is the first of many Higgs bosons which are
waiting to be discovered. Higgs bosons with electric
charge ("charged Higgs bosons" or "charged scalars")
are predicted in many extensions of the Standard Model.
Searches for such particles are being carried out at the
LHC, in particular in the decays of the top quark, and
these searches assume that two specific decay modes of
the charged Higgs boson are dominant: In this talk I show
that a third decay mode, into charm and bottom quarks,
can be dominant in models with more than two Higgs
isospin doublets. So far there has been no dedicated
search for this decay to charm and bottom quarks at the
LHC, but it could readily be performed as an extension of
an ongoing search which assumes that the charged Higgs
boson decays into a charm quark and a strange quark. |
