Perturbative QCD Corrections to the Z Boson Width and the Higgs Decay Rate
Radiative QCD corrections significantly influence the theoretical predictions for the decay rates of the Z and the Higgs boson. The status of the QCD calculations to the hadronic Z width is reviewed. The role of mass corrections from bottom quark final states is emphasized. An estimate of the theoretical uncertainties is given. New results for quar-tic mass terms of order O(α 2 s) are presented...
متن کاملStatus of Perturbative Qcd Evaluation of Hadronic Decay Rates of the Z and Higgs Bosons
We review the current status of the high order perturbative QCD evaluation of the hadronic decay rates of the Z and Higgs bosons. A systematic classification of the various types of QCD corrections to O(α 2 s) and O(α 3 s) is made and their numerical status is clarified.
متن کاملNeutrinoless double beta decay from lattice QCD
While the discovery of non-zero neutrino masses is one of the most important accomplishments by physicists in the past century, it is still unknown how and in what form these masses arise. Lepton number-violating neutrinoless double beta decay is a natural consequence of Majorana neutrinos and many BSM theories, and many experimental efforts are involved in the search for these processes. Under...
متن کاملAn estimate of the QCD corrections to the decay Z →
We present an estimate of perturbative QCD corrections to the decay Z → Wud̄. A simple approximate approach is described in detail. The difference of masses of MZ and MW is used as an expansion parameter. A complete analytical formula for a part of the corrections is also presented.

متن کاملHiggs and Z bosons decay into light gluinos.
We calculate the decay rate of scalar and pseudoscalar Higgs bosons into a pair of gluinos, within the Minimal Supersymmetric Standard Model. In the theoretically and experimentally allowed light gluino window, m ~ g 3{5 GeV, gluino pairs can completely dominate the decays of the light scalar Higgs boson and play a prominent role in the decay of the pseudoscalar Higgs boson. This would alter th...
