abstract
We compute the effects due to the virtual exchange (or the soft emission) of a scalar particle with generic couplings to the top quark in $t\bar t$ pair production at the LHC. We apply the results to two cases of interest, extending and completing previous studies. First, we consider the indirect search for light ($m_S<2 m_t$) top-philic scalars with CP-even and/or CP-odd interactions. Second, we investigate how to set constraints on anomalous Yukawa couplings of the Higgs boson to the top quark. Our results show that the current precision of experimental data together with the accuracy of the SM predictions make such indirect determinations a powerful probe for new physics.

Quantum Tomography of Top Quarks as a Probe of Charge-Parity Violation
Combining the full 15-parameter spin-state (quantum tomography) data on top-quark pairs with a complete one-loop calculation bounds the CP-violating part of the top-Higgs coupling at a level comparable to dedicated tt...

Extracting a Toponium Signal at the LHC with Spin and Quantum Information Tools
Spin and quantum-information observables add only marginal statistical power beyond kinematic variables for isolating toponium in near-threshold top-pair events, but improve interpretability.

New physics in toponium's shadow?
Consistently including toponium bound-state effects inside the new-physics amplitude, not just the Standard Model one, reshapes the allowed mass–coupling region for a top-philic pseudoscalar near the top-antitop threshold.

Constraining ALP-Top Interaction from the Chromoelectric Dipole Moment of the Top Quark
The paper derives the one- and two-loop top quark CEDM induced by a CP-violating ALP at q^2 = m_t^2 and uses it to set new bounds on the ALP-top coupling, with the neutron EDM giving the strongest of the three new limits.
