Search for third generation scalar and vector leptoquarks in the context of a stop search at LHC — ferdinand krieter, •kyeong ro lee, and alexander mann — Ludwig-Maximilians-Universität München

Leptoquarks (LQs) are hypothetical bosons coupling both to quarks and leptons. Leptoquarks are interesting since they might provide an explanation for similarities between the quark and lepton sector and lepton-universality violation observed in B-anomalies. Assuming there exist leptoquarks coupling to third-generation fermions (i.e. top and bottom quarks, tau leptons and neutrinos), the direct decay products of LQ pairs produced in pp collisions will be similar to final states of stop (SUSY partner of top quark) pairs. Thus a similar strategy applies to the LQ search and the stop search with corresponding optimizations. Currently, there are open possiblities for both scalar (s=0) and vector (s=1) LQs, so an additional goal is to extend the LQ search to vector LQ.
