T-Odd Gluon-Top-Quark Couplings at LHC

الأصل · EN

The T-odd top-quark chromoelectric dipole moment, dₜ, is probed through top-quark-pair production via gluon fusion at the CERN LHC with the possibility of having polarized proton beams in account. At 1-σ level, the typical CP-odd lepton energy and tensor correlations enable us to measure Re(dₜ) and Im(dₜ) up to the order of 10⁻¹⁸ (gₛcm) in the unpolarized case and the initial CP-odd gluon spin correlation allows us to probe Im(dₜ) up to the order of 10⁻²⁰ (gₛcm) for √s=14 TeV and the integrated luminosity Lpp=10 fb⁻¹.
