Laura++ : a Dalitz plot fitter
read the original abstract
The Dalitz plot analysis technique has become an increasingly important method in heavy flavour physics. The Laura++ fitter has been developed as a flexible tool that can be used for Dalitz plot analyses in different experimental environments. Explicitly designed for three-body decays of heavy-flavoured mesons to spinless final state particles, it is optimised in order to describe all possible resonant or nonresonant contributions, and to accommodate possible CP violation effects.

Method to study $CP$ violation in $B_s^0\to K_S K^\pm \pi^\mp$ decays
A method is developed to relate amplitudes for B_s^0 → K_S K* resonances in the two final states, enabling the first tagged decay-time-dependent Dalitz analysis to measure the effective weak phase φ_s^eff.

Unbinned extraction of $\gamma$ from $B\to DK$ with normalizing flows
Normalizing flows trained on D decay data create a continuous unbinned model of Dalitz plot amplitudes, allowing extraction of gamma from B decay data with successful recovery of injected values in Monte Carlo tests.
