The CP violating phase Φ s in the B 0 s → J/ψφ decay is predicted in Standard Model to be Φ s = −2β s where β s is related to the Cabibbo-Kobayashi-Maskawa matrix elements as In the Standard model Φ s is very small but New Physics contribution can enhance it quite significantly. The LHC experiments are in a very good position to measure the β s angle thanks to the large beauty production cross-section and the high luminosity of the machine. In the present document the status of the trigger and
