Leptoquark searches in TESLA

Leptoquark searches are considered for possible future e+e− and e±γ experiments at TESLA. Expected exclusion limits from direct leptoquark searches are compared with indirect limits expected from the contact interaction analysis. If the leptoquark signal suggested by the existing data is detected at LHC, with mass below 1 TeV, TESLA will be an ideal place to study its properties, provided that the leptoquark Yukawa coupling is not too small.
