摘要:

在完全NLO电弱水平下,采用mSUGRA破缺方案,在双Higgs二重态模型和最小超对称标准模型中计算了LHC中顶夸克与带电Higgs的产生过程.我们已经在两个典型的超对称的情况下,特别注意的tan β的依赖性,我们已经发现,他们仍然微扰小,但可能是相当大的,达到20%的极限tan β的极值,当考虑到完整的费曼图。

英文摘要:

The process of charged Higgs production in association with a top quark at the LHC has been calculated at the complete NLO electroweak level both in a Two Higgs Doublets Model and in the Minimal Supersymmetric Standard Model, assuming a mSUGRA breaking scheme. We have numerically explored the size of the one-loop corrections in two typical supersymmetric scenarios, with particular attention to the tan beta dependence, and we have found that they remain perturbatively small but possibly sizable, reaching a 20% limit for extreme values of tan beta, when the complete set of Feynman diagrams is taken into account.
