Résumé:	In this thesis we examine the virtual Leptoquarks (LQ) exchange in the ˆu-channel of the q process, where we consider that direct LQ production is inaccessible to current colliders. By calculating the total cross section at the partonic level, accounting for both Standard Model (W exchange) and New physics contributions, we investigate the impact of LQ exchange and the emergence of contact interactions (CI). Using CI energy scale bounds from Deep Inelastic Scattering (DIS) experiments, we establish upper limits on LQ coupling. − Keywords: scalar leptoquark, cross section, contact interaction¯q → ¯νe−
