Contributions of leptoquark interactions into the tensor and scalar form factors of K to pi l nu

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/41415In the framework of scalar-vector dominance we calculate the hadronic matrix elements of scalar and tensor effective quark currents induced by virtual leptoquark interactions. Combined bounds on the product of couplings and leptoquark masses are obtained from experimental data.19 pages, 15 eps-figures, discusion on the lepton polarization addedHigh Energy Physics - PhenomenologyContributions of leptoquark interactions into the tensor and scalar form factors of K to pi l nu_l decaytext
