Electroweak and Flavor Dynamics at Hadron Colliders

TL;DR

This paper catalogs potential signatures of electroweak and flavor dynamics at hadron colliders, focusing on technicolor models and related phenomena, to guide experimental searches at energies around 1 TeV.

Contribution

It provides a comprehensive overview of collider signatures specific to technicolor and flavor dynamics models, including new particles and decay channels, for the 1996 Snowmass workshop.

Findings

Technicolor signatures include technirho production and decay into technipions and weak bosons.

Distinctive angular and rapidity distributions help identify these processes.

High invariant mass dijet and dilepton excesses may indicate flavor substructure.

Abstract

We catalog the principal signatures of electroweak and flavor dynamics at $\pbarp$ and $pp$ colliders for use at the 1996 Snowmass Workshop on New Directions in High Energy Physics. The framework for dynamical symmetry breaking we assume is technicolor, with a walking coupling $\atc$, and extended technicolor. The reactions discussed occur mainly at subprocess energies $\rshat \simle 1\,\tev$. They include production of color-singlet and octet technirhos and their decay into pairs of technipions, longitudinal weak bosons, or jets. Technipions, in turn, decay predominantly into heavy fermions. Many of these signatures are also expected to occur in topcolor-assisted technicolor. Several particles specific to this new scenario are discussed. Additional signatures of flavor dynamics, associated with quark and lepton substructure, may be sought in excess production rates for high $E_T$ and invariant mass dijets and dileptons. An important feature of these processes is that they exhibit fairly central angular and rapidity distributions.
