An analysis of the Dalitz plots for the decays $D^+\to K^-\pi^+\pi^+$ and $D^+\to\pi^-\pi^+\pi^+$ indicates that structure with significant phase variation is required in the s-wave $K^-\pi^+$ and $\pi^-\pi^+$ systems in the region below 1…

We introduce an unbinned method for extracting the CKM angle $\gamma$ from the decay chain $B^\pm \to (D \to K_S \pi^+ \pi^-) K^\pm$ using normalizing flows (NFs). The NFs, trained on $D$ decay data, learn a faithful continuous…
