摘要:
A measurement of the time-dependent CP-violating asymmetry in $$ {B}_s^0\to \phi \phi $$ decays is presented. Using a sample of proton-proton collision data corresponding to an integrated luminosity of 5.0 fb−1 collected by the LHCb experiment at centre-of-mass energies $$ \sqrt{s} $$ = 7 TeV in 2011, 8 TeV in 2012 and 13 TeV in 2015 and 2016, a signal yield of around 9000 $$ {B}_s^0\to \phi \phi $$ decays is obtained. The CP-violating phase $$ {\phi}_s^{s\overline{s}s} $$ is measured to be −0.073 ±...
