New Physics at HERA: Implications for e+e- Scattering at LEP2

Abstract

The impact of virtual leptoquark or R-parity breaking squark exchange as well as generic contact interactions on the production of quark-antiquark pairs in $e^{+}{e}^{-}$ annihilation, in particular at LEP2, is summarized. An exciting possibility of sneutrino formation in $e^{+}{e}^{-}$ scattering is also mentioned.
