Prof. Kajari Mazumdar (Tata Inst., Mumbai, India)3/10/06, 11:00 AMHiggs and EWSBOralSearch 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.Go to contribution page

Dr Sven Heinemeyer (University of Zaragoza)3/10/06, 11:20 AMHiggs and EWSBOralFeynHiggs 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,...Go to contribution page

Dr SANTOSH RAI (Harish-Chandra Research Institute)3/11/06, 9:00 AMHiggs and EWSBOralWe 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 ->...Go to contribution page

Dr Sukanta Dutta (SGTB Khalsa College, University of Delhi.)3/11/06, 9:20 AMHiggs and EWSBOralThe 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.Go to contribution page

Dr Aura Rosca (West University of Timisoara)3/11/06, 9:40 AMHiggs and EWSBOralWe 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.Go to contribution page

Philip Bechtle (SLAC)3/13/06, 9:00 AMHiggs and EWSBOralThis 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...Go to contribution page

Dr Arnaud Ferrari (University of Uppsala)3/13/06, 9:20 AMHiggs and EWSBOralThe 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...Go to contribution page

Prof. Edmond Berger (High Energy Physics Division, Argonne National Laboratory, USA)3/13/06, 10:00 AMHiggs and EWSBOralI 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...Go to contribution page

Sudhansu Biswal (CHEP, IISc. Bangalore)3/13/06, 11:20 AMHiggs and EWSBOralWe 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...Go to contribution page

Dr Dong-Won Jung (Korea Institute of Advanced Study ( KIAS))3/13/06, 11:40 AMHiggs and EWSBOralWe 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...Go to contribution page

Mr Sudhir Gupta (Harish-Chandra Research Institute)3/13/06, 12:00 PMHiggs and EWSBOralWe 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...Go to contribution page
