First model-independent Dalitz analysis of B0→DK∗0, D→KS0π+π− decay
First model-independent Dalitz analysis of B0→DK∗0, D→KS0π+π− decay
We report a measurement of the amplitude ratio |$r_S$| of |$B^0 \to D^0K^{\ast 0}$| and |$B^0 \to \bar {D^0}K^{\ast 0}$| decays with a Dalitz analysis of |$D\to K_S^0\pi ^+\pi ^-$| decays, for the first time using a model-independent method. We set an upper limit |$r_S < 0.87$| at the 68% …
