Abstract:

Searches are reported for Higgs bosons in the context of either the standard model extended to include a fourth generation of fermions (SM4) with masses of up to 600 GeV or fermiophobic models. For the former, results from three decay modes (蟿蟿, WW, and ZZ) are combined, whilst for the latter the diphoton decay is exploited. The analysed proton-proton collision data correspond to integrated luminosities of up to 5.1 fb-1 at 7 TeV and up to 5.3 fb-1 at 8 TeV. The observed results exclude the SM4 Higgs boson in the mass range 110-600 GeV at 99% confidence level (CL), and in the mass range 110-560 GeV at 99.9% CL. A fermiophobic Higgs boson is excluded in the mass range 110-147 GeV at 95% CL, and in the range 110-133 GeV at 99% CL. The recently observed boson with a mass near 125 GeV is not consistent with either an SM4 or a fermiophobic Higgs boson. 漏 2013 CERN.

CLEO-c and CESR-c: Allowing Quark Flavor Physics to Reach its Full Potential

ArXiv hep-ex/0207091 (2002)

Abstract:

We report on the physics potential of a proposed conversion of the CESR machine and the CLEO detector to a charm and QCD factory: ``CLEO-c and CESR-c'' that will make crucial contributions to quark flavor physics this decade, and may offer our best hope for mastering non-perturbative QCD, which is essential if we are to understand strongly coupled sectors in the new physics that lies beyond the Standard Model.

Abstract:

An a priori search for inclusive photon + lepton production was made. It was found that subsamples of this data set agree well with their standard model (SM) prediction, with the possible exception of 纬鈩撯垊T.
