We propose a sensitive measurement of the charm total cross-section at RHIC through muon identification from charm semileptonic decay at low transverse momentum (pT ). This can test the binary-collision scaling (Nbin) properties of the charm total cross-section and be used to study whether heavy-flavor quarks, which are used as a probe, are produced exclusively at the initial impact in hadron-h...

Production of the lightest MSSM Higgs boson h is studied at the LHC. Isorate contours for the h → γγ and h → ττ decay channels are shown in the (mA, tanβ) parameter space. Effects of the SUSY parameters, in particular the stop mixing and stop quark mass, are investigated. Search strategies at the LHC are discussed and the discovery potential is calculated for the CMS experiment. The MSSM parame...

The search for supersymmetry (SUSY) is a major goal of the Tevatron Run II and LHC physics programs. If SUSY exists at the electroweak scale, SUSY partners of the Standard Model (SM) particles will either be discovered at these hadron colliders, or a very large region of SUSY parameter space will be excluded, provided reliable theoretical predictions in next-to-leading order (NLO) SUSY-QCD are ...

Various 2-particle direct photon-hadron correlation yields in p + p and Au + Au collisions at √ sNN = 200 GeV are presented. The per-trigger yield of direct photon hadron pairs from direct-photon-jet correlations is obtained by a statistical subtraction of the decay photon pairs from inclusive photon-hadron sample. The decay photon pertrigger yields are estimated from the measured π-hadron by m...

In this talk we discuss gluon radiation in top production and decay. After reviewing results for hadron colliders we consider soft gluon radiation at lepton colliders and present gluon distributions that are potentially sensitive to production-decay interference effects.

We report the final results of the CP-PACS calculation for the quenched light hadron spectrum with the Wilson quark action. Our data support the presence of quenched chiral singularities, and this motivates us to use mass formulae based on quenched chiral perturbation theory in order to extrapolate hadron masses to the physical point. Hadron masses and decay constants in the continuum limit sho...
