High Level Tracker Triggers for CMS
Two fast trigger algorithms based on 3 innermost hits in the CMS Inner
Tracker are presented. One of the algorithms will be applied at LHC low
luminosity to select B decay channels. Performance of the algorithm is
demonstrated for the decay channel Bs->Ds+pi. The second algorithm will be used
to select tau-jets at LHC high luminosity.Comment: 10 pages, 10 figures, to be published in the Vertex 2001 Conference

SM and MSSM Higgs Boson Production: Spectra at large transverse Momentum
Strategies for Higgs boson searches require the knowledge of the total
production cross section and the transverse momentum spectrum. The large
transverse momentum spectrum of the Higgs boson produced in gluon fusion can be
quite different in the Standard Model and the Minimal Supersymmetric Standard
Model. In this paper we present a comparison of the Higgs transverse momentum
spectrum obtained using the PYTHIA event generator and the HIGLU program as
well as the program HQT, which includes NLO corrections and a soft gluon
resummation for the region of small transverse momenta. While the shapes of the
spectra are similar for the Standard Model, significant differences are
observed in the spectra of Minimal Supersymmetric Standard Model benchmark
scenarios with large tan(beta).Comment: 8 pages, 13 figure
