11. Determination of CKM angle $ \phi_{3} $ at Belle and Belle II / Niharika Rout [BELLE2-CONF-PROC-2021-006]
05 March 2021

We present the measurement of the angle $ \phi_{3} $ using a model-independent Dalitz plot analysis of $ B^{\pm} \to DK^{\pm}, D \to K_{S}^{0}\pi^{+}\pi^{-} $ decays, which currently provides the best sensitivity. [...]
