Περίληψη:
Promptly decaying lightest charginos were searched for in the context of
scenarios with gravitino LSP. It was assumed that the stau is the next
to lightest supersymmetric particle (NLSP). Data collected with the
DELPHI detector at a centre-of-mass energy near 183 GeV were analysed
combining the methods developed in previous searches. No evidence for
the production of these particles was found. Hence, limits were derived
at 95% confidence level. The mass of charginos was found to be greater
than 85.5 GeV/c(2) for m(<(chi)over bar>1+) -m(<(tau)over bar>1) greater
than or equal to 0.3 GeV/c(2), independently of the mass of the
gravitino. (C) 1999 Published by Elsevier Science B.V. AU rights
