Boucrot, J Jacholkowska, A Isolated photons and constraints on anomalous WW$\gamma$ couplings at LEP2 Events with isolated single photons or multiphotons have been studied in LEP 2 ALEPH data. The sensitivity to the W W gamma anomalous couplings has been determined for various kinematic ranges and for different energies. The resulting constraints on the anomalous coupling parameters delta(kappa_gamma) and lambda_gamma are derived from the total cross sections and from differential distributions. eng 1997
