D0-D0 mixing parameter y in the factorization-assisted topological-amplitude approach

  • We calculate the D0-D0 mixing parameter y in the factorization-assisted topological-amplitude (FAT) approach,considering contributions from D0→PP,PV,and VV modes,where P (V) stands for a pseudoscalar (vector) meson.The D0→PP and PV decay amplitudes are extracted in the FAT approach,and the D0→VV decay amplitudes with flnal states in the longitudinal polarization are estimated via the parameter set for D0→PV.It is found that the VV contribution to y,being of order of 10-4,is negligible,and that the PP and PV contributions amount only up to yPP+PV=(0.21±0.07)%,a prediction more precise than those previously obtained in the literature, and much lower than the experimental data yexp=(0.61±0.08)%.We conclude that D0 meson decays into other two-body and multi-particle flnal states are relevant to the evaluation of y,so it is difficult to understand it fully in an exclusive approach.

Abstract: We calculate the D0-D0 mixing parameter y in the factorization-assisted topological-amplitude (FAT) approach,considering contributions from D0→PP,PV,and VV modes,where P (V) stands for a pseudoscalar (vector) meson.The D0→PP and PV decay amplitudes are extracted in the FAT approach,and the D0→VV decay amplitudes with flnal states in the longitudinal polarization are estimated via the parameter set for D0→PV.It is found that the VV contribution to y,being of order of 10-4,is negligible,and that the PP and PV contributions amount only up to yPP+PV=(0.21±0.07)%,a prediction more precise than those previously obtained in the literature, and much lower than the experimental data yexp=(0.61±0.08)%.We conclude that D0 meson decays into other two-body and multi-particle flnal states are relevant to the evaluation of y,so it is difficult to understand it fully in an exclusive approach.
