Dear all,

In case you have missed it; we unblinded the B_s^0->J/psiKK CP-violation measurement this morning: https://indico.cern.ch/event/312475/contribution/3/material/slides/0.pdf https://indico.cern.ch/event/312475/contribution/4/material/slides/0.pdf

The subtitle of Greig's talk was "The Standard Model wins again"...:

-------------------------------------------------------------------- phi_s^av = -0.05 +/- 0.05 (stat.) +/- 0.01 (syst.) (-0.04) Delta phi_s^para = -0.02 +/- 0.04 (stat.) +/- 0.01 (syst.) (0) Delta phi_s^perp' = -0.00 +/- 0.03 (stat.) +/- 0.01 (syst.) (0) Delta phi_s^S = +0.02 +/- 0.06 (stat.) +/- 0.02 (syst.) (0)

C_s^av = -0.01 +/- 0.04 (stat.) +/- 0.00 (syst.) (0) Delta C_s^para = -0.03 +/- 0.12 (stat.) +/- 0.05 (syst.) (0) Delta C_s^perp = +0.04 +/- 0.16 (stat.) +/- 0.02 (syst.) (0) C_s^avS = +0.06 +/- 0.03 (stat.) +/- 0.02 (syst.) (0)

Delta Gamma_s = +0.081 +/- 0.009 +/- 0.003 ps^-1 (0.087 +/- 0.021) --------------------------------------------------------------------

Where the numbers between brackets are the (naive) Standard Model predictions.
