At the LHC we consider, within the MSSM, the production of neutral Higgs
bosons via gg-fusion and bb-annihilation and the subsequent decay of these
bosons into tau+ tau- pairs. We analyze observables which allow to
discriminate between scalar and pseudoscalar Higgs bosons and states of
undefined CP parity. NLO QCD corrections are taken into account.

The dominance of $h\to \eta \eta$ decay mode for the intermediate mass
Higgs boson is highly motivated to solve the little hierarchy
problem and to ease the tension with the precision data.
However, the discovery modes for $m_h \alt 150$ GeV,
$h \to \gamma\gamma$ and $W/Z h \to (\ell\nu/\ell \bar \ell) (b\bar b)$,
will be substantially affected.
We show that $h \to \eta \eta \to 4b$...

We examine the mixing between a light CP-odd Higgs boson and eta_b states and its
implications
in the decay rates and masses of both physical (mixed) states in different scenarios
beyond
the minimal extension of the Standard Model. Special emphasis is put on the
phenomenology to be observed at high luminosity B factories.

The SU(3) simplest little Higgs model, with the mu term introduced by hand,
accommodates light pseudo-scalar boson, eta. The eta mass can be at 10-100 GeV scale.
For lighter eta, the sizable coupling of H-eta-eta leads to dominant decay of the Higgs boson
into a pair of eta's especially when mH below the WW threshold. Another new decay channel
of H->Z eta can be dominant or compatible with...

Singlet Higgs bosons present in extensions of the MSSM can have sizable
Yukawa couplings to the b quark and the tau lepton for large values of tan
(beta) at the 1-loop level. We present an effective Lagrangian which
incorporates these tan(beta)-enhanced Yukawa couplings and which enables
us to study their effect on singlet Higgs-boson phenomenology within the
context of both the mnSSM...
