Search for the Higgs boson is the principal motivation of the LHC experiments.
Potential of discovery will be presented from simulation studies by both CMS and
ATLAS collaborations in the context of beyond Standard Model scenarios. We shall also
discuss the relevant experimental issues.

FeynHiggs is a program for computing MSSM Higgs-boson masses and related observables,
such as mixing angles, branching ratios, couplings and production cross sections,
including state-of-the-art higher-order contributions (also for the case of explicit
CP-violation). The centerpiece is a Fortran library for use with Fortran and C/C++.
Alternatively, FeynHiggs has a command-line,...

Feasibility of the measurement of the trilinear self-coupling of the Higgs boson is
studied. Double higgs strahlung as well as WW fusuion processes are under investigation.

We study the dilepton-dijet signal in the dominant Higgs production channel at a
linear e+ e- collider. We show that by taking a simple ratio between cross-sections
of two different final states different new physics scenarios can be identified. The
case of distinguishing radions from Higgs is consisdered. We also highlight the
effects of new particles in the loop contributing to the H ->...

The T parity conserving Little Higgs Model predicts the existence of heavy gauge
bosons. We probe the production of heavy charged gauge bosons in the upcoming
gamma-gamma collider. We further study its decay to heavy neutral gauge bosons (a
promising dark matter candidate) and W bosons.

We investigate the double Higgs production process at the ILC, focusing on the
measurement of the trilinear self coupling of the Higgs boson in the fusion channel.
The sensitivity of this measurement is discussed in the Higgs mass range 140-200 GeV
at a center of mass energy between 1 TeV to 1.5 TeV.

This talk presents the legacy of the four LEP experiments ALEPH, DELPHI, L3 and OPAL
in the field of the search for Higgs bosons which are predicted within the framework
of the Minimal Supersymmetric Standard Model (MSSM). It will focus on the search for
neutral Higgs bosons. The data of the four collaborations are statistically combined
and show no signicant excess of events which would...

The Minimal Supersymmetric Extension of the Standard Model (MSSM) predicts the
existence of new charged and neutral Higgs bosons. The pair creation of these new
particles at the multi-TeV e+e- Compact Linear Collider (CLIC), followed by decay
cascades into Standard Model particles, were simulated along with the corresponding
background. Beam-beam effects such as ISR, beamstrahlung and...

We present new correctins to Higgs boson masses and mixing angles in the MSSM with
real and complex parameters. A numerical analysis of the impact of these new

I present a QCD calculation of the transverse momentum distributions of
Higgs bosons, and of photon pairs produced by 'background' QCD
subprocesses, including all-orders soft-gluon resummation valid at
next-to-next-to-leading logarithmic accuracy. Resummation is needed to
obtain predictions valid in the ranges of transverse momentum where the
cross sections are largest. I compare...

We examine, in a model independent way, the sensitivity of a Linear Collider to the
couplings of a light Higgs boson to gauge bosons. Including the possibility of CP
violation, we construct several observables that probe the different anomalous
couplings possible. For an intermediate mass Higgs, a collider operating at a center
of mass energy of 500 GeV and with an integrated luminosity...

We consider a possibility that electroweak symmetry breaking (EWSB) is triggered by
both a fundamental Higgs and a composite Higgs arising in a dynamical symmetry
breaking mechanism induced by a new strong dynamics. The resulting Higgs sector is
a partially composite two-Higgs doublet model with specific boundary conditions on
the coupling and mass parameters originating at a...

We examine the possibility of detecting signals of split supersymmetry in the loop-
induced decay h --> gamma gamma of the Higgs boson at the Large Hadron Collider,
where charginos, as surviving light fermions of the supersymmetric spectrum, can
contribute in the loop. We perform a detailed study of uncertainties in various
parameters involved in the analysis, and thus the net...
