Abstract
We point out new ways to search 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 Kpi/pipi modes; the argument may be extended to B-->gamma+X(s), and perhaps to lnu+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(*)pn, D(*)pppi not far below D(*)pi and D(*)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.
