TL;DR

This study conducts a broad, model-independent search for new physics in lepton final states using Tevatron data, finding no significant deviations from the standard model predictions.

Contribution

It introduces a comprehensive, model-independent analysis method applied to 117 final states in proton-antiproton collisions at 1.96 TeV.

Findings

No evidence for physics beyond the standard model

All discrepancies explained by background uncertainties

Analysis of 1.1 fb$^{-1}$ data from D0 detector

Abstract

We describe a model independent search for physics beyond the standard model in lepton final states. We examine 117 final states using 1.1 fb$^{-1}$ of $p \bar{p}$ collisions data at $\sqrt{s} = 1.96$ TeV collected with the D0 detector. We conclude that all observed discrepancies between data and model can be attributed to uncertainties in the standard model background modeling, and hence we do not see any evidence for physics beyond the standard model.
