Search for Time-Reversal Violation in the Decay of Polarized 8Li Nuclei
نویسندگان
چکیده
202301-1 The transverse polarization of electrons emitted in the decay of polarized 8Li nuclei has been measured. For the time-reversal violating triple correlation parameter we find R 0:9 2:2 10 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, mLQ > 560 GeV=c2 (90% C.L.), is obtained.

Study of time reversal violation in b decay of polarized Li
The transverse polarization in a plane perpendicular to the nuclear spin axis has been determined for electrons emitted in the b decay of polarized Li. Such a spin component signals a violation of time reversal symmetry. Using a sample of Li nuclei with vector polarization of ;0.11 and a polarimeter with average analyzing power S520.10, the asymmetry in the Mott scattering of decay electrons wa...
متن کاملSearch for Time-Reversal Invariance Violation with High Intensity Neutron Beam
The important advantage to the search for Time-Reversal invariance violation (TRIV) in neutron nuclei interactions is the possibility of an enhancement of T-violating observables by many orders of magnitude due to the complex nuclear structure (see, i.e. paper [1] and references therein). Moreover, the variety of nuclear systems to measure T-violating parameters provides assurance that a possib...

The methods of investigation of Time Reversal Invariance (TRI) violation using polarized neutron beam and polarized or aligned nuclear target are briefly considered. The new method of dynamic nuclear alignment (DNA) of quadrupolar nuclei is proposed. An implementation of this method can significantly increase the number of aligned nuclei accessible for TRI violation experiments and for the othe...
متن کاملMeasurement of the polarization vector of the e+ from the decay of polarized μ+ as a test of time reversal invariance
Abstract The complete polarization vector of the positrons from the decay of polarized muons has been measured for the first time with one experimental setup. The μPT experiment at the Paul Scherrer Institute determines the three polarization components simultaneously with the same apparatus by making use of three different effects (spatial and temporal dependence of annihilation-in-flight with...
متن کاملSearching for T-Violating, P-Conserving New Physics with Neutrons
The observance of parity conserving time reversal violation in light quark systems could signal the presence of physics beyond the Standard Model. I discuss the implications of low-energy time reversal tests for the existence of such T-violating, P-conserving (TVPC) interactions. I argue that searches for permanent electric dipole moments (EDM’s) and direct TVPC searches provide complementary i...
