Dibosons from CMS

TL;DR

This paper reports measurements of diboson production cross sections at 7 TeV by CMS, including $W\,\gamma$, $Z\,\gamma$, $WW$, $WZ$, and $ZZ$, with interpretations of anomalous couplings based on early data.

Contribution

First measurements of multiple diboson production channels at 7 TeV by CMS, including interpretation of anomalous triple gauge couplings from early data.

Findings

Measured cross sections for $W\,\gamma$, $Z\,\gamma$, $WW$, $WZ$, and $ZZ$ production.

First 2011 measurements with 1.1 fb$^{-1}$ data.

Results consistent with Standard Model predictions.

Abstract

It is here presented the diboson production cross section measured by the CMS collaboration in $pp$ collisions data at $\sqrt{s}$=7 TeV. $W \gamma$ and $Z \gamma$ results from 2010 analyses (36 pb$^{-1}$) are presented together with 2011 first measurements of $WW$, $WZ$ and $ZZ$ final states obtained using 1.1 fb$^{-1}$. Results obtained with 2010 data are also interpreted in term of anomalous triple gauge couplings.
