Prospects for triple gauge boson couplings measurements in CMS
We investigate the CMS potential for the observation and study of the proton proton -> ZZ -> e+e-e+e- and proton proton -> WZ -> 3l (l=e, mu) reactions, using fully simulated signal and background samples. It is shown that these processes are potentially accessible with early CMS data, thanks to relatively high production cross sections at LHC energies, together with clear signatures of the multi-lepton final states. The main systematic effects relevant for cross section measurements with 1 and 10 inverse femtobarn of data are addressed. We demonstrate that multiple gauge-boson production in proton proton collisions at LHC energies can be observed in the early phase of the experiment, with an integrated luminosity of 1 inverse femtobarn or less. We also address the prospects for measuring anomalous gauge couplings in these channels.
