Abstract

Data from a 70 GeV proton-iron beam-dump experiment and the theoretical predictions of light Higgs production from the decays π ± →e ± V (∼) e H, K ± →e ± V (∼) e H, K ± →π ± H, K 0 L →π 0 H, η′→η′H were used to establish limits on the mass of a scalar Higgs boson in the context of the standard model. The mass range 1 m H c 2 was excluded at 95% CL.

Abstract

A search has been performed for weakly interacting neutral light scalar and pseudoscalar particles in a proton-iron beam dump experiment via the Bethe-Heitler process. No positive signal was observed. Limits are derived on the masses of these particles in the framework of the Standard Model and its minimal supersymmetric extension (MSSM) comparing the experimental results with expectations for Bethe-Heitler e+e− and μ+μ− pair production. The Higgs particle of the SU2L×U1 Standard Theory is excluded for masses in the range mH
