Yukawa Induced Radiative Corrections to the Lightest Higgs Boson Mass in the NMSSM
We compute the leading logarithmic radiative corrections to the lightest Higgs mass in the NMSSM involving the electroweak gauge couplings and the NMSSM specific Yukawa couplings λ and κ (including all mixed combinations), which are induced by chargino, neutralino and Higgs boson loops. The effect of the NMSSM specific Yukawa couplings λ and κ is to increase the upper bound on the lightest Higg...
متن کاملTwo–Loop Radiative Corrections to the Lightest Higgs Boson Mass in the Minimal Supersymmetric Model
In the minimal supersymmetric model (MSSM), the upper limit of the lightest Higgs boson mass, mh0 , depends strongly on the top quark mass, mt. We have computed the dominant twoloop radiative corrections to this upper limit of mh0 in order to eliminate large uncertainties due to QCD and mt corrections. It is shown that the QCD corrections significantly reduce the one-loop corrections. As a resu...

We study the 1-loop corrections to the charged Higgs production both in the Minimal Supersymmetric Standard Model (MSSM) and in a more general type II two-Higgs-doublet model (THDM-II). We consider the full set of corrections (including soft photon contributions as well as box diagrams), and define a parametrization that allows a comparison between the two models. Besides the soft photon radiat...
متن کاملRadiative Corrections to Bremsstrahlung in Radiative Return
Radiating a photon from the initial state provides a useful tool for studying a range of low energy physics using a high-energy ee accelerator. Accurate results require careful calculation of the first order virtual photon corrections. We compare exact results for initial state radiative corrections, finding agreement to an order of 10 or better as a fraction of the Born cross-section for most ...
متن کاملRadiative corrections to the decays
We calculate the rates and lepton (l) invariant mass distributions for decays of the form 0−+ → l+l−γ, which are important radiative corrections to the purely leptonic decays 0−+ → l+l−. Our approach uses the loop diagrams which arise by including the two photon intermediate state and we retain the imaginary parts of the loops a radiative extension of the ‘unitarity bound’ for the process. Thes...
