New limit on T violation in neutron decay
Description
We have measured the triple correlation D of the neutron polarisation and the momenta of electron and antineutrino, dW∝1+DP(pe x pν-bar), in neutron beta decay. Our result is D=[-2.8±6.4(stat)±3.0(syst)]x10-4. The corresponding phase between gA and gV in V-A-theory follows as phiAV=180.04 deg. ±0.09 deg. This result improves the limit on a possible T violation in neutron beta decay
