Pathways to Rare Baryonic B Decays

Zusammenfassung

We point out new ways to search for charmless baryonic B decays: baryon pair production in association with \$\eta^\prime\$ is very likely as large as or even a bit larger than two body \$K\pi/\pi\pi\$ modes. We extend our argument, in weaker form, to \$B+ X\_s\$ and \$\ell+X\$. Although calculations are not reliable, estimates give branching ratios of order \$10^-5\$--\$10^-6\$, where confidence is gained from recent experimental finding that \$B D^* p n\$, \$D^* p p \pi\$ are not far below \$D^*\pi\$ and \$D^*\rho\$ rates. Observation of charmless baryon modes would help clarify the dynamics of weak decays to baryonic final states, while the self-analyzing prowess of the \$Łambda\$-baryon can be helpful in CP- and T-violation studies.
