Search for stable heavy charged particles in e(+)e(-) collisions at root
s=130-136, 161 and 172 GeV

Αγγλικά

A search for stable or long-lived heavy charged particles in e(+)e(-)
interactions at energies of 130-136, 161 and 172 CeV has been performed
using the data taken by the DELPHI experiment at LEP. The search is
based on particle identification provided by the Time Projection Chamber
and the Ring Imaging Cherenkov detector. Upper limits at 95% confidence
level are derived on the cross-section for heavy long-lived
pair-produced charge +/-e and +/-2/3e particles in the range of 0.4-2.3
pb for masses from 45 to 84 GeV/c(2). Within supersymmetric extensions
of the Standard Model, long-lived charginos with masses from 45 to 84
(80) GeV/c(2) for high (low) sneutrino masses can be excluded at 95%
confidence level. Left-handed (right-handed) long-lived or stable smuons
and staus with masses between 45 and 68 (65) GeV/c(2) can be excluded at
95% confidence level. (C) 1997 Elsevier Science B.V.
