Sažetak
Leptoquarks are hypothetical bosonic particles with a unique property ; they can transform quarks into leptons and vice versa. Leptoquarks can explain many things like the B-physics anomalies, so they are often present in phenomenological extensions of the Standard Model. There is a large number of scientific articles that cover questions of the leptoquark production and ways of their detection at Large Hadron Collider (LHC). LHC can produce leptoquarks in several different ways. Production mechanism that is best studied in literature is the pair production which is dominant for small Yukawa couplings. However, with the increase of the Yukawa couplings, the phenomenology of leptoquarks becomes more interesting and diverse. Namely, for large Yukawa couplings there are also additional leptoquark production mechanisms: t-channel production, single production, Drell-Yan di-lepton production and a resonant production. Moreover, there has recently been introduced a novel leptoquark production mechanism [1] that is of the t-channel topology which gives asymmetric leptoquark pairs in the final state. The article shows that the novel production mechanism has the potential to be more important than other leptoquark production mechanisms in limiting certain parts of the parameter space that is described by the relevant Yukawa couplings and leptoquark masses. This presentation will provide the most recent studies of that particular leptoquark production mechanism at LHC.
