We study the T odd correlations induced by CP violating anomalous top-quark couplings at both production and decay level in the process gg --> t t_bar --> (b mu+ nu_mu) (b_bar mu- nu_mu_bar). We consider several counting asymmetries at the parton level and find the ones with the most sensitivity to each of these anomalous couplings at the LHC.

  1. Quantum detection of CP violation in the $t\bar{t}$ system: tomography

    hep-ph 2026-07 conditional novelty 6.0

    Polar-angle tomography reconstructs the ttbar production density matrix while b–lepton azimuthal sine modulations linearly probe CP-odd Wtb decay couplings, separating production from decay CP violation.

  2. Quantum detection of CP violation in the $t\bar{t}$ system: production

    hep-ph 2026-07 conditional novelty 6.0

    CP-odd SMEFT top interactions appear as ΔB and antisymmetric C_A in the tt̄ production density matrix; direct markers beat most QI measures for CP sensitivity at LHC and FCC-ee.
