Tests for Time Reversal Violation
We illustrate two new theoretical conditions under which a two-body decay of a resonance violates time reversal invariance. As a consequence, we deduce two different kinds of tests of time reversal violation for such decays. The tests proposed may help detecting possible signals of physics beyond the Standard Model. In particular, they are sensitive to contributions of spontaneous CP violation....
متن کاملTime Reversal Violation
This talk briefly reviews three types of time-asymmetry in physics, which I classify as universal, macroscopic and microscopic. Most of the talk is focussed on the latter, namely the violation of T-reversal invariance in particle physics theories. Talk presented at Discrete ’08 Conference, Valencia, Spain December 11, 2008 SLAC–PUB–13518 This work is supported by the Department of Energy under ...
متن کاملTable-top Time-reversal Violation
Many electrical and mechanical systems with two normal modes are appropriate for illustrating the quantum mechanics of neutral kaons. The illustration of CPor time-reversal-violation in the neutral kaon system by mechanical or electrical analogues is more subtle. Some possibilities which could be realized in a table-top demonstration are suggested.
متن کاملCan We Investigate Direct Time Reversal Violation?
We illustrate a theoretical condition under which a two-body decay of a resonance violates time reversal invariance. Moreover, we examine some cases for which this condition looks particularly simple. As a consequence, we deduce tests of time reversal violation for weak decays involving spinning particles.

متن کاملNew limit on time-reversal violation in beta decay.
We report the results of an improved determination of the triple correlation DP·(p(e)×p(v)) that can be used to limit possible time-reversal invariance in the beta decay of polarized neutrons and constrain extensions to the standard model. Our result is D=[-0.96±1.89(stat)±1.01(sys)]×10(-4). The corresponding phase between gA and gV is ϕAV=180.013°±0.028° (68% confidence level). This result rep...
