摘要:
Using a dataset corresponding to an integrated luminosity of 3.0 fb−1 collected in pp collisions at centre-of-mass energies of 7 and 8 TeV, the B 0  → ϕϕ branching fraction is measured to be $$ \mathrm{\mathcal{B}}\left({B}_s^0\to \phi \phi \right)=\left(1.84\pm 0.05\left(\mathrm{stat}\right)\pm 0.07\left(\mathrm{syst}\right)\pm 0.11\left({f}_s/{f}_d\right)\pm 0.12\left(\mathrm{norm}\right)\right)\times 1{0}^{-5}, $$ where f s /f d represents the ratio of the B 0 to B 0 production cross-section...
