Search for the Radiative Decays $B\to \Lambda \bar{p} \gamma$ and $B\to \Sigma^0 \bar{p} \gamma$

We report the results of a search for the radiative baryonic decays $B\to \Lambda \bar{p} \gamma$ and $B\to \Sigma^0 \bar{p} \gamma$ in a sample of 380 million $B$ decays recorded at the $\Upsilon(4S)$ resonance of the PEP-II facility with the BaBar detector. We present branching fractions for these channels and investigate mass and angular distributions of the di-baryon system, which provide insight into the decay mechanism.
