Bounds on Scalar Leptoquarks from the LEP Data

High Energy Physics - Phenomenology 2008-02-03 v2

Abstract

We obtain the constraints on scalar leptoquarks coming from radiative corrections to ZZ physics. We perform a global fitting to the LEP data including the contributions of the most general effective Lagrangian for scalar leptoquarks, which exhibits the SU(2)L×U(1)YSU(2)_L \times U(1)_Y gauge invariance. Our bounds on leptoquarks that couple to the top quark are much stronger than the ones obtained from low energy experiments.
