Abstract

Neutral Higgs bosons of the Standard Model (SM) and the Minimal Supersymmetric Standard Model (MSSM) were searched for in the data collected in 1999 by the DELPHI experiment at centre-of-mass energies between 191.6 and 201.7 GeV with a total integrated luminosity of 228 pb(-1). These analyses, in combination with our results at lower energies, set 95% confidence level lower mass bounds on the Standard Model Higgs boson (107.3 GeV/c(2)) and on the lightest neutral scalar (85.9 GeV/c(2)) and neutral pseudoscalar (86.5 GeV/c(2)) Higgs bosons in representative scans of the MSSM parameter space. An extended scan of the MSSM parameter space was also performed to test the robustness of these limits.

Abstract

Oscillations of B0s mesons have been studied in samples selected from about 3.5 million hadronic Z decays detected by DELPHI between 1992 and 1995. One analysis uses events in the exclusive decay channels: B0s → D-sπ+ or D-sa+1 and B0s → D̄0K-π+ or D̄0K-a+1, where the D decays are completely reconstructed. In addition. B0s-B0s̄ oscillations have been studied in events with an exclusively reconstructed Ds accompanied in the same hemisphere by a high momentum hadron of opposite charge. Combining the two analyses, a limit on the mass difference between the physical B0s states has been obtained: ΔmB0s > 4.0 ps-1 at the 95% C.L. with a sensitivity of ΔmB0s = 3.2 ps-1. Using the latter sample of events, the B0s lifetime has been measured and an upper limit on the decay width difference between the two physical B0s states has been obtained: τB0s = 1.53+0.16-0.15(stat.) ± 0.07(syst.) ps ΔΓB0s/ΓB0s < 0.69 at the 95% C.L. The combination of these results with those obtained using D±sℓ∓ sample gives: ΔmB0s > 4.9 ps-1 at the 95% C.L. with a sensitivity of ΔmB0s = 8.7 ps-1. τB0s = 1.46 ± 0.11 ps and ΔΓB0s/ΓB0s < 0.45 at the 95% C.L.

Abstract

A search for sleptons, neutralinos, charginos, sgoldstinos and heavy stable charged sleptons in the context of scenarios where the lightest supersymmetric particle is the gravitino, is presented. Data collected during 2000 with the DELPHI detector at centre-of-mass energies from 204 to 208 GeV were analysed and combined with all the data collected from 1995 to 1999 at lower energies. No evidence for the production of sleptons, neutralinos and charginos has been found, therefore new limits on the mass of these supersymmetric particles and on the model parameter space are set. The search for heavy stable charged sleptons also updates the stable sleptons mass limit. The absence of evidence for sgoldstino production allows limits to be set on its mass and on the scale of supersymmetry breaking.
