    abstract = "The data collected by DELPHI in 1998 at the centre-of-mass energy of 189
GeV have been used to update the search for charginos nearly
mass-degenerate with the lightest supersymmetric particle, which is
assumed to be the lightest neutralino. Mass differences below Delta M =
3 GeV/c(2) are considered. No excess of events with respect to the
Standard Model expectation has been observed, and exclusions in the
plane of Delta M versus chargino mass are given. The new Delta M
independent lower limit on the mass of the chargino is 62.4 GeV/c(2) in
the higgsino scenario (which includes the gaugino mass unification
scenario), if all sfermions are heavier than the lightest chargino. In
the approximation of large sfermion masses the limit is 59.8 GeV/c(2),
independently of the field content. (C) 2000 Published by Elsevier
