Abstract
The rare decay B¯d0âJ/ÏÏ can proceed via four distinct mechanisms: (i) production of the Ï via tri-gluon fusion, (ii) photoproduction of the J/Ï or Ï, (iii) final-state rescattering of Ds(â)Ds(â) produced in the B¯d decay to J/ÏÏ, and (iv) production of the Ï via Ï-Ï mixing. In this work, we examined the contributions of photoproduction and final-state rescattering to B¯d0âJ/ÏÏ and found that the corresponding branching ratios were of the orders 10â11 and 10â9, respectively. Hence, this decay is dominated by the Ï-Ï mixing effect.
