A Quasi-Model-Independent Search for New High p_T Physics at DZero

TL;DR

This paper employs a quasi-model-independent approach called 'Sleuth' to search for new high transverse momentum physics phenomena in Fermilab Tevatron data, but finds no evidence of such new physics.

Contribution

It introduces the 'Sleuth' method for broad, model-independent searches for high p_T new physics in collider data.

Findings

No evidence of new high p_T physics was observed.

The method demonstrates sensitivity to various models predicting new phenomena.

Systematic analysis of multiple final states was performed.

Abstract

We apply a quasi-model-independent strategy ("Sleuth") to search for new high p_T physics in approximately 100 pb^-1 of ppbar collisions at sqrt(s) = 1.8 TeV collected by the DZero experiment during 1992-1996 at the Fermilab Tevatron. We systematically analyze many exclusive final states and demonstrate sensitivity to a variety of models predicting new phenomena at the electroweak scale. No evidence of new high p_T physics is observed.
