Anomalous couplings in the Higgs-strahlung process
Abstract
The angular distributions in the Higgs-strahlung process e+e- HZ H f f are uniquely determined in the Standard Model. We study how these predictions are modified if non-standard couplings are present in the ZZH vertex, as well as lepton-boson contact terms. We restrict ourselves to the set of operators which are singlets under standard SU3× SU2× U1 transformations, CP conserving, dimension 6, helicity conserving, and custodial SU2 conserving.
