Search for charginos nearly mass-degenerate with the lightest neutralino $e^+e^-$ collisions up to $\sqrt{s}$ = 209GeV
Search for chargino nearly mass-degenerate with the lightest neutralino is performed with the data collected at a centre-of-mass energy from 189 to 209~GeV by the ALEPH detector at LEP. The analysis uses the detection of an isolated and energetic initial state radiation photon, produced in associati...
