Search for Sm and Mssm Higgs Bosons at Lep *
The four LEP experiments (ALEPH, DELPHI, L3 and OPAL) collected around 2.5 fb data in total at energies √ s ≥ 189 GeV of which 536 pb was registered at √ s = 206−209 GeV in 2000. The data are used to search for Higgs bosons in a variety of models. In the Standard Model (SM) the electroweak (EW) symmetry is broken via the Higgs mechanism generating the masses of elementary particles. This implie...
متن کاملQuantum corrections for the MSSM Higgs couplings to SM fermions
Higgs Yukawa couplings to down-type fermions receive, in the MSSM, supersymmetric quantum corrections that can be of order 1 for large values of tanβ, provided |μ| ∼ MSUSY. Therefore, a sensitive prediction for observables driven by any of these couplings can only be obtained after an all-order resummation of the large corrections. We perform this necessary step and show, as an example, the eff...
متن کاملDistributions for Higgs + jet at hadron colliders: MSSM vs SM
We present pseudorapidity and transverse momentum distributions for the cross section for the production of the lightest neutral Higgs boson in association with a high-pT hadronic jet, calculated in the framework of the minimal supersymmetric standard model. We discuss the theoretical predictions for the differential cross sections at the Large Hadron Collider and the Tevatron. In particular, w...
متن کاملSearches for beyond Sm Higgs Boson at the Tevatron
The Higgs mechanism is the heart of the Standard Model (SM) providing masses to gauge bosons via electroweak symmetry breaking (EWSB). However, the SM fails to explain the origin of the Higgs mechanism and has certain naturalness problems, such as the extreme fine tuning required to keep the higher order corrections to the higgs mass under control (the so called hierarchy problem). In popular S...
متن کاملSearches for non-SM Higgs at the Tevatron
Recent results obtained by the CDF and D0 Collaborations on searches for Higgs bosons beyond the Standard Model at Run II of the Tevatron are discussed. The data, corresponding to integrated luminosities of up to 4.2 fb −1 , are compared to theoretical expectations. No significant excess of signal above the expected background is observed in any of the various final states examined, and so limi...
