Possible large violation in three body decays of heavy baryon
We propose a new mechanism which can introduce large asymmetries in the
phase spaces of three-body decays of heavy baryons. In this mechanism, a large
asymmetry is induced by the interference of two intermediate resonances,
which subsequently decay into two different combinations of final particles. We
apply this mechanism to the decay channel , and
find that the differential asymmetry can reach as large as , while
the regional asymmetry can reach as large as in the interference
region of the phase space.Comment: 7 pages, 2 figures, 2nd version accepted by Phys. Lett.
