Four-body baryonic B→B1B¯1′B2B¯2′ decays
LHCb has recently reported the first observation of a four-body baryonic B→B1B¯1′B2B¯2′ decay, where B1B¯1′ and B2B¯2′ represent the two pairs of octet baryon states. In our classification, the measured B¯0→pp¯pp¯ decay is a tree dominated process via internal W-boson emission, whose branching fract...
