Search For New Particles in Multijet Final States at the Tevatron

TL;DR

This paper reports on searches for new particles in multijet final states at the Tevatron, using proton-antiproton collision data, finding no evidence of new physics but setting limits on possible particle masses and cross sections.

Contribution

It provides the latest experimental limits on new particles in multijet events at the Tevatron, based on data from 1992-1995, with no discovery of new phenomena.

Findings

No evidence of new particles found in multijet events.

Data consistent with Standard Model QCD predictions.

Limits set on masses and cross sections of potential new particles.

Abstract

We present the latest results of the searches for new particles in hadronic final states performed in proton-antiproton collisions at a center of mass energy of 1.8 TeV. The large data samples collected with the CDF and D0 detectors at the Tevatron collider between 1992 and 1995 allow searches for low cross section phenomena in dijet and multijet events, despite the hindrance of the high background from normal QCD processes. However, no signal for new physics is found, and the data show good agreement with QCD. Limits on the mass and on the cross section of the searched states can thus be set.
