Leptoquarks and Contact Interactions from a Global Analysis
Aleksander Filip Zarnecki
Abstract
Data from HERA, LEP and the Tevatron, as well as from low energy experiments are used to constrain the scale of possible electron-quark contact interactions. Some models are found to describe the existing experimental data much better than the Standard Model. The possibility of scalar or vector leptoquark contribution is studied using the Buchmuller-Ruckl-Wyler effective model. Increase in the global probability observed for scenarios including S1 or ~Vo leptoquark production/exchange corresponds to more than a 3 sigma effect. Assuming that a real leptoquark signal is observed, calculated is an allowed region in the coupling-mass plane.
