Revisiting the scalar leptoquark $$(S_1)$$ ( S 1 ) model with the updated leptonic constraints

Abstract

Abstract The Standard Model, if extended to the energy scale of $${\mathscr {O}}(1)$$ O ( 1 ) TeV, the known particle spectrum could be augmented with a scalar leptoquark. Within this minimally extended framework, explaining the anomalous magnetic moment and electric dipole moment simultaneously for the three lepton generations over a parameter space consistent with all the lepton flavor violating bounds is possible. Such a model can be tested or falsified through the collider search experiments and/or by probing the low-energy lepton phenomena. This work studies the current prospects of the model in the presence of recent experimental updates for the leptonic observables.
