Abstract
We study non-standard top-gluon-coupling effects from possible beyond-the-standard-model physics through top-quark pair productions at hadron colliders, i.e., Tevatron/LHC. We calculate the total cross section σ(pp → t¯t) at LHC, and also the top-quark-jet angular distribution in t¯t productions at both Tevatron and LHC as a function of two anomalous-coupling parameters, i.e., the chromoelectric and chromomagnetic moments of the top, which are constrained by the total cross section σ(p¯p → t¯tX) measured at Tevatron. We find that there will be some chances to observe sizable effects induced by those new couplings.
