LEP 2 e+e-->ffbar, gamma gamma (gamma): results and interpretations

TL;DR

This paper presents results from LEP 2 on e+e- to fermion pairs and gamma gamma production, comparing them with Standard Model predictions and setting limits on new physics models, including Low Scale Gravity, while also summarizing LEP beam energy measurements.

Contribution

It provides experimental results on e+e- and gamma gamma production at LEP 2 and interprets these in the context of Standard Model and beyond, including limits on new physics.

Findings

Results agree with Standard Model predictions.

Limits set on Low Scale Gravity models.

Summary of LEP beam energy determination.

Abstract

Results on LEP 2 e+e-->ffbar and gamma gamma (gamma) production are presented. These are compared with Standard Model predictions, and then used to set limits on various New Physics models, including Low Scale Gravity. Finally the status of the LEP beam energy determination from radiative return events is summarised.
