Asymmetries in Three-Body Decays of the B-Meson

We suggest to analyze the three-body decays B+- to $K+- p pbar$ and to $K+- \pi \pi$ by means of two different asymmetries. The former asymmetry, a T-odd one, vanishes and is proposed as a test for excluding biases in the experimental data. The latter asymmetry, which is T-even, may be useful in singling out time reversal odd contributions to the decay, and, possibly, hints at physics beyond the standard model.
