HiggsSignals is a Fortran90 computer code that allows to test the compatibility of Higgs sector predictions against rates and masses measured at LHC or Tevatron. Arbitrary models with any number bosons can be investigated using model-independent input scheme based on HiggsBounds. The calculation $$\chi ^2$$ measure from masses, ability fully taking into account systematics correlations for signal rate predictions, luminosity mass predictions. It features two complementary methods test....
We describe the new developments in version 4 of public computer code HiggsBounds. HiggsBounds is a tool to test models with arbitrary Higgs sectors, containing both neutral and charged bosons, against published exclusion bounds from searches at LEP, Tevatron LHC experiments. From model predictions for masses, branching ratios, production cross sections total decay widths—which are specified by user input program—the calculates predicted signal rates search channels considered experimental...
LHC searches for non-standard Higgs bosons decaying into tau lepton pairs constitute a sensitive experimental probe physics beyond the Standard Model (BSM), such as Supersymmetry (SUSY). Recently, limits obtained from these have been presented by CMS collaboration in nearly model-independent fashion - narrow resonance model based on full 8 TeV dataset. In addition to publishing 95% C.L. exclusion limit, likelihood information has released. This provides valuable that can be incorporated...
