QCD Interference Effects of Heavy Particles Below Threshold
arXiv:hep-ph/9601279 · doi:10.1016/0370-2693(96)00670-3
Abstract
We consider how two classes of heavy particles: extra vector-like families, and strongly interacting superpartners, manifest themselves below threshold, by interference of virtual loops with normal QCD processes. Quantitative estimates are presented.
