We constrain the physical Higgs mass by using a set of assumptions related to the high-energy behavior of “bare” parameters of the effective Standard Model. In the regular case we find that the Higgs mass must lie in the window 160(168) ≤ m H < 295 GeV. In the unconventional case, with opposite sign for running of the scalar’s mass, we find that the Higgs must be lighter than roughly vEW ≈ 246 ...

New limits on couplings λjk , which break both the baryon number and the R–parity, are derived by using a new mechanism that contributes to the neutronanti-neutron oscillation. The constraints due to proton decay and its potential phenomenology are also reexamined. The minimal supersymmetric standard model (MSSM) [1] has been widely considered as a leading candidate for new physics beyond Stand...

Upper limits on the cross section for Standard-Model Higgs-boson production in p¯ p → H + X at √ s = 1.96 TeV are determined for 100 < mH < 200 GeV/c 2. The contributing processes include associated production (W H → νb ¯ b, ZH → + − /ν ¯ νb ¯ b, and W H → W W + W −) and gluon fusion (H → W + W −). Analyses are conducted with integrated luminosities from 260 pb −1 to 950 pb −1 recorded by the D...

This paper provides a critical analysis of the BPSim standard, a specification by the Workflow Management Coalition. The aim of this standard is to make it possible to exchange simulation models between different modeling and simulation tools. We discuss the expressiveness of BPSim model and come to the conclusion that it will be sufficient for certain cases, but also lacks some important featu...
