| | Abstract: Although the Lepton Flavor Violating (LFV) decay u+ - e+
is forbidden in the Standard Model (SM), it can take place within various theories beyond the SM. If the branching ratio of this decay saturates its present bound [i.e., Br(u+ - e+) 10-11], the forthcoming experiments can measure the branching ratio with high precision and consequently yield information on the sources of LFV. In this seminar, we show that for polarized +, by studying the angular distribution of the transversely polarized positron and linearly polarized photon we can derive information on the CP-violating sources beyond those in the SM. We also study the angular distribution of the nal particles in the decay + - e +1ee+2 where e+1 is de ned to be the more energetic positron. We show that transversely polarized e + 1 can provide information
on a certain combination of the CP-violating phases of the underlying theory which would be lost by averaging over the spin of e +1.
