Leptoquarks in SUSY Unified Models and the HERA Events
نویسنده
چکیده
Motivated by the recent HERA events which are consistent with a possible leptoquark interpretation, we discuss the prospects for including additional light colour triplets and anti-triplets in the spectrum of supersymmetric unified theories. We focus on a particular string-inspired Pati-Salam model, and propose a simple mechanism by which a light colour triplet of charge -1/3 plus anti-triplet of charge 1/3, may have a mass of order 200 GeV, with one of the new states having leptoquark couplings and with proton decay suppressed. We also discuss possible scenarios for gauge unification in such a model. Research supported in part by grant numbers GR/K55738, TMR contract ERBFMRX-CT96-0090 and ΠENE∆-15815/95 April 1997

Recent HERA Results on Leptoquarks and other SUSY-related Signatures
The HERA ep collider and the experiments H1 and ZEUS operated from 1994-2007. A total integrated luminosity of almost 1fb−1 was collected at centre-of-mass energies up to 320 GeV. Results from searches for leptoquarks and squarks, final states with an isolated lepton and missing transverse momentum and final states with multi-leptons are presented. The leptoquark limits are interpreted in terms...
متن کاملSEARCHES FOR LEPTOQUARKS, SQUARKS IN 6 Rp SUSY AND EXCITED FERMIONS AT HERA
Various searches for leptoquarks, scalar quarks in Rp-violating supersymmetric models, and excited fermions performed by the HERA experiments H1 and ZEUS are reviewed. No evidence for new particle production was observed from data collected by both experiments since 1994 in either electron-proton and positron-proton collisions. Stringent limits derived on the masses and couplings of these new p...
متن کاملRecent HERA Results Sensitive to SUSY
Recent results of searches for new physics at HERA using the complete data sample corresponding to about 0.5 fb per experiment are reviewed. Searches for leptoquarks, isolated leptons (electrons, muons and taus) and a generic search for new physics in many topologies are reported. No evidence for new physics is found. The ep collisions at HERA are ideally suited to search for resonantly produce...
متن کاملMuch Ado About Leptoquarks: A Comprehensive Analysis *
We examine the phenomenological implications of a N 200 GeV leptoquarks in light of the recent excess of events at HERA. Given the relative predictions of events rates in e+p versus e–p, we demonstrate that classes of leptoquarks may be excluded, including those contained in EG GUT models. It is shown that future studies with polarized beams at HERA could reveal the chirality of the leptoquarks...
متن کاملNeutral and charged current cross section measurements and searches for new physics at HERA
HERA is the only high energy electron–proton collider in the world today and hence has unique opportunities both to probe the structure of the proton and to search for physics beyond the Standard Model. Results are presented for measurements of both neutral and charged current cross sections, and for searches for exotic processes involving direct electron–quark interactions (leptoquarks and R–p...
