Young Scientist Forum Measurement of VZ production cross sections in Vbb decay channels in pp collisions at 8 TeV with the CMS experiment.

A measurement of the VZ (V=W,Z) production cross section in proton-proton collisions at $\sqrt{s}$=8 TeV in the VZ ->Vbb decay mode with, Z->vv,ll and W->lv (l=e,$\mu$) is presented. The results are based on data corresponding to an integrated luminosity of 18.9/fb collected with the CMS ex...

description A measurement of the VZ (V=W,Z) production cross section in proton-proton collisions at $\sqrt{s}$=8 TeV in the VZ ->Vbb decay mode with, Z->vv,ll and W->lv (l=e,$\mu$) is presented. The results are based on data corresponding to an integrated luminosity of 18.9/fb collected with the CMS experiment. The process is observed for the first time in this particular final state with a significance exceeding six standard deviations. The cross sections we determined $\sigma$(pp->WZ) and $\sigma$(pp->ZZ) are consistent with the predictions of NLO calculations.

The results are based on data corresponding to an integrated luminosity of 18.9 fb$^{-1}$ collected with the CMS experiment. The process is observed for the first time in this particular final state with a significance exceeding six standard deviations ($\sigma$). The measured cross sections are consistent with the predictions of NLO calculations.arXiv:1405.2739CMS-CR-2014-057oai:cds.cern.ch:17011262014-05-05
