- Abstract:
-
Charm meson oscillations are observed in a time-dependent analysis of the ratio of D⁰ → K⁺π⁻π⁺π⁻ to D⁰ → K⁻π⁺π⁻π⁺ decay rates, using data corresponding to an integrated luminosity of 3.0 fb^⁻1 recorded by the LHCb experiment. The measurements presented are sensitive to the phase-space averaged ratio of doubly Cabibbo-suppressed to Cabibbo-favored amplitudes rDK3π and the product of the coherence factor RDK3π and a charm mixing parameter y'K3π. The constraints measured are rDK3π=(5.67±0.12)×1...
