  Title Measurement of CP asymmetries in (B)over-bar0 → Ds- D+ and (B)over-bars0 →Ds- D- decays Type Journal Article
  Year 2026 Publication Journal of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume 08 Issue 8 Pages 056 - 22pp  
  Keywords B Physics; CP Violation; Flavour Physics; Hadron-Hadron Scattering  
  Abstract Measurements of the combined CP asymmetries in (B) over bar (0) -> D-s(-) D+ and (B) over bar (0)(s) -> D-s(-) D- decays are made using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb(-1). The measurements are found to be A(CP) ((B) over bar (0) -> D-s(-) D+) = 0.0009 +/- 0.0053 +/- 0.0040, A(CP) ((B) over bar (0)(s) -> D-s(-) D-) = 0.103 +/- 0.053 +/- 0.010, where the first and second uncertainties are statistical and systematic, respectively. This is the first measurement of this asymmetry in (B) over bar (0)(s) decays, and the most precise measurement to date for (B) over bar (0) decays. Both measurements are found to be consistent with CP symmetry.
