英文摘要:
We examine the possibility of observing exotic top quark decays via R-parity violating SUSY interactions in e(+)e(-) collisions at roots = 500 GeV. We present cross-sections for tt production followed by the subsequent decay of either the t or (t) over bar via the R-parity violating interaction while the other undergoes the SM decay. We discuss kinematic cuts that allow the exotic SUSY decays to be detected over standard model backgrounds. Discovery limits for R-parity violating couplings in the top sector are presented assuming an integrated luminosity of 100 fb(-1). (C) 2001 Published by Elsevier Science B.V.
