Search for charginos with a small mass difference to the lightest supersymmetric particle at s = 189 GeV
Abstract
A search for charginos nearly mass-degenerate with the lightest supersymmetric particle is performed using the 176 pb−1 of data collected at 189 GeV in 1998 with the L3 detector. Mass differences between the chargino and the lightest supersymmetric particle below 4 GeV are considered. The presence of a high transverse momentum photon is required to single out the signal from the photon-photon interaction background. No evidence for charginos is …
