Probing nonstandard top-quark couplings using spin correlation
- Center for Particle Physics, University of Texas, Austin, Texas 78712 (United States)
Top spin correlation has been shown to be nontrivial in hadronic top-quark pair production, and can be realized by the asymmetries of the decay products of the top quark and antiquark. We show in this work that the top spin correlation is a sensitive probe to the anomalous top-quark couplings beyond the standard model. Specifically, we look at the anomalous chromomagnetic and chromoelectric dipole moments, as well as a right-handed component in the weak decay of the top quark. We find a few measurable asymmetries formed by the decay products of the top-quark pair that vary in accord with the spin correlation. {copyright} {ital 1997} {ital The American Physical Society}
