Model independent constraints on leptoquarks from rare processes

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We present model independent constraints on the masses and couplings to fermions ofB andL conserving leptoquarks. Such vector or scalar particles could have masses below 100 GeV and be produced at HERA; we list the generation dependent bounds that can be calculated from rare lepton and meson decays, meson-anti-meson mixing and various electroweak tests.
