Title: Search for Higgs Bosons and Supersymmetry at the Tevatron

Abstract

Since the start of Run II in March 2001 the Tevatron collider has delivered pp-bar collisions corresponding to about 3 fb{sup -1} to the CDF and DOe experiments. This report presents a brief summary of recent results based on this dataset from the searches for Higgs bosons and Supersymmetry.

  • We investigate the prospects for the detectability of the Higgs bosons of the minimal supersymmetric model (MSSM) at future colliders. First we delineate regions of MSSM parameter space where the various Higgs bosons may be observable at the CERN [ital e][sup +][ital e[minus]] collider LEP 200 or hadron supercolliders, assuming (as usual) that Higgs-boson decay modes to supersymmetric particles are not allowed. We find that, even with optimistic assumptions of detector capabilities, there exist regions of parameter space where none of the Higgs bosons are visible. Next, we show that there are substantial regions of parameter space where rates formore » Higgs-boson decays to supersymmetric particles are large, and even dominant. These decays reduce the rates for conventional Higgs-boson signatures, thus making conventional detection of Higgs bosons even more difficult. However, a number of new, promising modes for Higgs-boson detection have opened up. These include a gold-plated'' Higgs scalar or pseudoscalar decay to four leptons plus missing energy which may make possible a precise mass measurement of the lightest and second lightest neutralino. Furthermore, rare decays of the top quark into a [ital b] quark plus three leptons may be visible, and signal charged-Higgs-boson decays to a chargino plus neutralino.« less
  • The prospects of detecting the {ital CP}-odd Higgs pseudoscalar ({ital A}) in the minimal supersymmetric model via its decay into a {ital Z} boson and the lighter {ital CP}-even Higgs scalar ({ital h}) at the CERN Large Hadron Collider are investigated. The final state of {ital Z}{r_arrow}{ital l}{sup +}{ital l}{sup {minus}} and {ital h}{r_arrow}{ital b{bar b}} may provide a promising way to simultaneously detect the {ital A} and the {ital h}. The compact muon solenoid detector performance is adopted for a realistic study of observability. In this discovery channel, the masses of the {ital h} and the {ital A} canmore » be reconstructed. The impact of supersymmetric decay modes is considered. {copyright} {ital 1996 The American Physical Society.}« less
  • The prospects for discovering neutral Higgs bosons in the minimal supersymmetric model (MSSM) and in the minimal supergravity model at the LHC are investigated. Two special discovery channels are discussed: (i) the decay mode of the MSSM CP-odd Higgs boson into photon pairs, and (ii) the decays of neutral Higgs bosons into muon pairs in the MSSM as well as in the minimal supergravity model. {copyright} {ital 1998 American Institute of Physics.}
