Constraints on scalar leptoquarks from lepton and kaon physics

14 Oct 2019 Mandal Rusa Pich Antonio

We present a comprehensive analysis of low-energy signals of hypothetical scalar leptoquark interactions in lepton and kaon transitions. We derive the most general effective four-fermion Lagrangian induced by tree-level scalar leptoquark exchange and identify the Wilson coefficients predicted by the five possible types of scalar leptoquarks...
