Multi-boson production

TL;DR

This paper reports on measurements of diboson production at the Tevatron collider, confirming Standard Model predictions and setting competitive limits on anomalous gauge couplings using data from proton-antiproton collisions.

Contribution

First comprehensive analysis of diboson production at Tevatron combining leptonic and semi-leptonic channels with up to 4.8 fb^{-1} of data.

Findings

Measured cross sections agree with Standard Model

Limits on anomalous triple gauge couplings are competitive

Analysis uses multiple final states and large data samples

Abstract

The studies of the diboson production in proton-antiproton collisions at 1.96 TeV performed by CDF and D0 collaborations at the Tevatron collider are reported in this paper. The diboson events are identified exploiting both leptonic and semi-leptonic final states. The presented results use different subsamples of the statistics collected by the Tevatron up to 4.8 1/fb. Measured production cross sections are in good agreement with Standard Model predictions and the limits on the anomalous triple gauge boson couplings are competitive with the ones measured by experiments at the LEP.
