Inclusive Higgs Boson Searches in Four-Lepton Final States at the LHC

The inclusive search for the Standard Model Higgs boson in four-lepton final states with the ATLAS and CMS detectors at the LHC pp collider is presented. The discussion focusses on the H-> ZZ^(*)->4l+X decay mode for a Higgs boson in the mass range 120 ~< M_H ~< 600 GeV/c^2. A prospective analysis is presented for the discovery potential based on a detailled simulation of the detector response in the experimental conditions of the first years of LHC running at low luminosity. An overview of the expected sensitivity in the measurement of the Higgs boson properties is also given.

Measurement of gauge boson couplings and W spin density matrix

During the LEP2 period the e+e- collider increased its center of mass energy from 161 GeV to 209 GeV and a total integrated luminosity of approximately 700 pb-1 was recorded per experiment. Pairs of W bosons are produced and allow the study of gauge boson couplings involving W, Z and photon. The coupling of the W boson to the neutral gauge bosons have been measured and are in agreement with the Standard Model prediction. Limits are set on CP-violating couplings by a Spin Density Matrix analysis of the W decay products. No evidence has been found for couplings of three neutral gauge bosons. Limits are derived on couplings of four gauge bosons.
