Abstract:

Searches for pair production of supersymmctric particles in e+e- collision at centre-of-mass energy of 183 GeV have been performed on DELPHI data under the assumption that R-parity is not conserved. Only one R-parity violating coupling of 位 type, which couples the sleptous to the leptons (LL膾 erm), is considered to be dominant at a time. Since in models with R-parity violation any supersymmetic particlr can be the lightest one, searches for charginos, neutralinos, sleptons and squarks have been perfomed both for direct R-parity violating decays and for indirect cascade decays. Morever, it is assumed that the strength of the R-parity violating couplings is such that the lifetimes can be neglected. The present study of supersymmetric particle pair production is used to exclude domains of the Minimal Supersymmetric Standard Model parameter space previously explored under the assumption of R-parity conservation.

Abstract:

Searches for neutral Higgs bosons in the Standard Model and the MSSM have been performed using data collected by the DELPHI experiment at a centre-of-mass energy of 188.7 GeV, corresponding to an integrated luminosity of 158 pb-1. These analyses are used, in combination with our results from lower energies, to set new 95% confidence level lower mass bounds on the Standard Model Higgs boson (94.6 GeV/c2) and on the lightest neutral scalar (82.6 GeV/c2) and neutral pseudoscalar (84.1 GeV/c2) Higgs bosons in a representative scan of the MSSM parameters. The results are also interpreted in the framework of a general two-Higgs doublet model.
