Abstract

We study the semileptonic decays of Bf0(1710,1500,1370)eν¯e, in which the three f0 states mix with glueball, s¯s, and (u¯u+d¯d)/2 states, respectively. By averaging the mixings fitted in the literature, we find that the branching ratios of Bf0eν¯e are O(106), O(106), and O(105), respectively, which can be simultaneously observed in experiments at B factories. The large predicted branching rate for Bf0(1370)eν¯e would provide a clean mode to directly observe the f0(1370) state.
