Collider sensitivity to SMEFT heavy-quark operators at one-loop in top-quark processes [PDF]

open access: yesarXiv
We study the effects of four-heavy-quark operators in the production of top quarks in the framework of the Standard Model Effective Field Theory (SMEFT) at the LHC. In particular, we compute for the first time the total contribution of the four-top-quark operator which enters only at the one-loop level in the top-quark pair production process ...

Symmetry breaking effects in pion couplings to constituent quark currents [PDF]

open access: yesarXiv
Pseudoscalar and axial neutral and charged pion-constituent quark coupling constants are investigated with nondegenerate quark masses in different kinematical points, off shell and on shell pions and constituent quarks. By considering a large quark mass expansion of a quark determinant in the presence of local pion field and of constituent quark ...
