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. It also provides a new limit on the mass of a possible scalar leptoquark, m_{LQ} > 560 GeV/c^2 (90% C.L.).
