Measurement of the charm mixing parameter using two-body meson decays

· Physical Review D
A measurement of the ratios of the effective decay widths of and decays over that of decays is performed with the LHCb experiment using proton–proton collisions at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of . These observables give access to the charm mixing parameters and , and are measured as , , where the first uncertainties are statistical and the second systematic. The combination of the two measurements is , which is four times more precise than the previous world average.
