    • Tagged time-dependent angular analysis of B0s→J/ψϕ decays with the 2010 LHCb data 

      LHCb Collaboration - CERN (2011-04)
      The interference between B0s decays to Jψϕ either directly or via B0s−B¯0s oscillation gives rise to a CP violating phase ϕJ/ψϕs. In the Standard Model, this phase is approximately -2βs, where βs = arg ...
