| dc.description | We consider the ratio of the cross section of production of heavy bottom-antibottom pairs ($σ_{b\bar b}$) to the cross section of production of top-antitop pairs ($σ_{t\bar t}$) at LHC. We show that in this ratio a major fraction of virtual contributions (including QCD components) disappears, leaving a residual dominant electroweak Yukawa effect that might be strongly enhanced in the presence of supersymmetry. A quantitative numerical analysis of the size of the effect is also performed under the assumption of a relatively light supersymmetric scenario. | |
