Single Leptoquark Production at TeV Energy $\gamma p$ Colliders

Abstract

The resolved and direct photon contributions to the single leptoquark (L) production process $\gamma p\to Le$ are analysed for both scalar (S) and vector (V) leptoquarks in detail. It is shown that resolved photon contribution dominates for $M_L\le 300GeV$. For $M_V\ge 1TeV$ and $M_S\ge 0.5TeV$ cross section is completely determined by the direct photon conribution. The vector leptoquarks are discussed for both gauge- and non-gauge cases seperately.
