Search for Leptoquarks and Lepton Flavor Violation at the H1 experiment

Abstract

We review recent preliminary results of searches for leptoquarks (LQs) with the H1 experiment at HERA. A search for first generation leptoquarks was performed using the e-p and e+p scattering data collected between 1994-2000 corresponding to an integrated luminosity Lint = 117 pb-1. In addition, the e+p H1 data set of the period 1999-2000 (Lint = 66 pb-1) was used to search for lepton flavor violating (LFV) processes mediated by second and third generation LQs. No evidence for direct or indirect production of LQs was found in either analysis. The analyses established constraints on the Yukawa coupling of LQs and LFV processes.
