Triple product asymmmetries in ${\Lambda }_b$ and ${\Xi }_b$ decays

Abstract

The LHCb experiment is capable of studying four-body decays of the $b$-flavored baryons ${\Lambda }_b$ and ${\Xi }_b^0$ to charmless final states consisting of charged pions, kaons, and baryons. We remark on the search in such modes for CP-violating triple product asymmetries and for CP rate asymmetries relative to decays involving charmed baryons.
