Pathways to rare baryonic B decays

We point out new ways to starch for charmless baryonic B decays and suggest that enhanced baryon production is favored by reduced energy release on the baryon side. Thus B --> eta ' + baryon pairs might be larger than K pi/pi pi modes: the argument may be extended to B --> gamma + X-s. and perhaps to l nu + X-u. Guess estimates give some branching ratios in the 10(-3)-10(-6) range, with confidence gained from the recent observation of B --> (D) over bar* p(n) over bar, (D) over bar* > not far below (D) over bar* pi and (D) over bar* rho rates. Observation of modes proposed here would help clarify the dynamics of weak decays involving baryons, while the self-analyzing prowess of Lambda decay can be helpful in CP- and T-violation studies.
