title: Search for time-reversal violation in the beta decay of polarized 8Li nuclei.
abstract: The transverse polarization of electrons emitted in the beta decay of polarized 8Li nuclei has been measured. For the time-reversal violating triple correlation parameter we find R=(0.9+/-2.2)x10(-3). This result is in agreement with the standard model and yields improved constraints on exotic tensor contributions to the weak interaction. Combined with other experimental results and using a model for the coupling constants, a new limit for the mass of a possible scalar leptoquark, m(LQ)>560 GeV/c(2) (90% C.L.), is obtained.
