Query: Status of the Charged Higgs Boson in Two Higgs Doublet Models   The existence of charged Higgs boson(s) is inevitable in models with two (or
more) Higgs doublets. Hence, their discovery would constitute unambiguous
evidence for new physics beyond the Standard Model (SM). Taking into account
all relevant results from direct charged and neutral Higgs boson searches at
LEP and the LHC, as well as the most recent constraints from flavour physics,
we present a detailed analysis of the current phenomenological status of the
charged Higgs sector in a variety of well-motivated Two Higgs Doublet Models
(2HDMs). We find that charged Higgs bosons as light as 75 GeV can still be
compatible with the combined data, although this implies severely suppressed
charged Higgs couplings to all fermions. In more popular models, e.g. the 2HDM
of Type II, we find that flavour physics observables impose a combined lower
limit on the charged Higgs mass of M_H+ > 600 GeV - independent of tan(beta) -
which increases to M_H+ > 650 GeV for tan(beta) < 1. We furthermore find that
in certain scenarios, the signature of a charged Higgs boson decaying into a
lighter neutral Higgs boson and a W boson provides a promising experimental
avenue that would greatly complement the existing LHC search programme for
charged Higgs boson(s).
