New Physics from HERA?

Abstract

The H1 and ZEUS experiments at the HERA $e^{\pm }p$ collider at Hamburg have recently reported some anomalous hard-scattering events, which could be indicative of new physics beyond the standard model. I have tried to discuss in a nonspecialist language the significance of this result for particle physics along with its interpretation in terms of the currently popular extensions of the standard model.
