The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

We study a CP and T violating triple (spin) correlation in the muon to electron conversion in nuclei in the context of the seesaw mechanism. After concluding that the results are negative for all three seesaw types, we turn to the left-right symmetric theories as the original source of seesaw. We find that in general this correlation is of order one which offers a hope of observing CP violation in lepton flavor violating processes for a L-R scale below around 10-30 TeV. We discuss the conditions that could render to (unlikely) conspiracies as to suppress the CP violating effects.

Here we present the first analytical computation for the correlation suggested in [ref] for the $μ→e$ conversion process and we extend their work in two ways: first, we compute the correlation for the $μ→eγ$ decay and second we include the full set of effective operators that enter the $μ→e$ conversion process.
