Erratum to: Updated measurement of time-dependent $$C\!P$$-violating observables in $${{B} ^0_{s}} \rightarrow J/\psi K^+ K^-$$ decays

Abstract

In the Introduction section of the original article [1].

First measurement of the $$C\!P$$-violating phase in $${{B} ^0_{s}} \!\rightarrow {{J /\psi }} ($$ $$\rightarrow $$ $$e ^+e ^-$$)$$\phi $$ decays

“…The correlation matrix of statistical uncertainties is reported in Table 5 of Appendix A. The results are consistent with previous measurements of these parameters [5,[10][11][12][13][14], and the SM predictions for φ s [24][25][26]. They show no evidence of CP violation in the interference between B 0 s meson mixing and decay, nor for direct CP violation in B 0 s → J/ψ (e + e − )φ decays, as the parameter |λ| is consistent with unity within uncertainties.…”

“…In contrast to Ref. [5], the S-wave parameters are measured in a single range of m(K + K − ) within ±30 MeV/c 2 of the known φ mass [15]. For a particles produced in a B 0 s and B 0 s flavour eigenstates, the coefficients in Eqs.…”

“…The analysis follows closely that of the two muons decay mode, reported in Refs. [5,7]. Relevant changes are described in more detail in this paper.…”

Erratum to: Updated measurement of time-dependent $$C\!P$$-violating observables in $${{B} ^0_{s}} \rightarrow J/\psi K^+ K^-$$ decays

“…In the Introduction section of the original article [1], the parameter λ was defined erroneously. The correct definition is λ ≡ (q/ p) A/A .…”

CP violation in beauty with the LHCb experiment

“…ps −1 . A LHCb Δ combination can be performed using 5 statistically independent measurement using the − + [1, 2], − + + − [3] and the / + − [4,5] final states. The corresponding Δ values are shown by the bottom plot in Fig.…”
