Contact Interaction Searches at the Linear Collider: Energy, Luminosity and Positron Polarization Dependencies

Abstract

Many types of new physics can lead to contact interaction-like modifications in $e^+e^-$ processes below direct production threshold. This report summarizes a survey of contact interaction search reaches at the Linear Collider as functions of energy, luminosity and positron polarization. The various tradeoffs between these quantities in such searches are examined in detail.
