Abstract
A signal in the decay channel D0 → K+ φ- was observed and its branching ratio relative to D0 → K- φ+ to be (0.404 ± 0.085 ± 0.025)% was measured. Results show that if charm sector mixing is signficant, the doubly Cabibbo suppressed component of the branching ratio can be determined from the measured ratio by using the relation expressed. While if the charm mixing is sufficiently small, the doubly Cabibbo suppressed branching ratio is simply equal to the measured ratio.File in questo prodotto:
