Query: Single Leptoquark Production at TeV Energy $\gamma p$ Colliders   The resolved and direct photon contributions to the single leptoquark (L)
production process $\gamma p\rightarrow L e$ are analysed for both scalar (S)
and vector (V) leptoquarks in detail. It is shown that resolved photon
contribution dominates for $M_{L}\leq 300 GeV$. For $M_{V}\geq 1 TeV$ and
$M_{S}\geq 0.5 TeV$ cross section is completely determined by the direct photon
conribution. The vector leptoquarks are discussed for both gauge- and non-gauge
cases seperately.
