Abstract
A new method for model-independent measurement of the CKM angle β is proposed, that employs time-dependent analysis of flavour-tagged B0 → Dπ+π− decays with D meson decays into \( \mathcal{C}\mathcal{P} \)-specific and K 0 s π+π− final states. This method can be used to measure the angle β with future data from the BelleII and LHCb experiments with the precision level of one degree.
