Description

We report on the first search for baryon-number-violating decay $B^- \to \bar{\Xi}_c^0 \Lambda_c^-$ using data collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. The results are also interpreted in terms of the previously-discovered Standard Model decay $B^- \to \Xi_c^0 \Lambda_c^-$ followed by possible $\Xi_c^0-\bar{\Xi}_c^0$ oscillations. The measurements of charmed baryons-antibaryon oscillations in the heavy quark sector provide a new avenue to investigate the origin of matter-antimatter asymmetry of the universe.
