Two-Body Charmless Baryonic B Decays at LHCb

The potential of the LHCb experiment to make the first discovery of a two-body charmless baryonic B decay is explored. The most promising channel is $B^0\rightarrow\p\={p}$ for which a $5\sigma$ discovery is possible with around 0.25 fb^-1 of LHCb data at nominal centre-of-mass energy, assuming that the value for the $B^0\p\={p}$ branching ratio is close to the current experimental upper limit. LHCb also has prospects for other two-body charmless baryonic B decays, such as $B_s\rightarrow\p\={p}$ and decays involving a $\Lambda$.
