Unbinned extraction of $\gamma$ from $B\to DK$ with normalizing flows

Yuval Grossman, Tony Menzo, Stefan Schacht +2

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 $D$ d…
