Identical particle interference in $D^{+}$ meson lifetime
A calculation is presented of the contribution to the D^{+} non- leptonic decay rate of the interference between the active and spectator d antiquarks, relating this effect to the shape of the electron energy spectrum in D semi-leptonic decay. Predictions for the D^{+} life-time and semi-leptonic br...

| Sumario: | A calculation is presented of the contribution to the D^{+} non- leptonic decay rate of the interference between the active and spectator d antiquarks, relating this effect to the shape of the electron energy spectrum in D semi-leptonic decay. Predictions for the D^{+} life-time and semi-leptonic branching ratio are also derived and discussed. |
