Systematic Parametrization of the B-meson Light-Cone Distribution Amplitude — •Philip Carlo Lüghausen1, Thorsten Feldmann1, and Danny van Dyk2 — 1Theoretische Teilchenphysik, Center for Particle Physics Siegen, Universität Siegen — 2Institute for Particle Physics Phenomenology, Durham University
This talk presents a novel approach to understanding B meson decays through the lens of the light-cone distribution amplitude (LCDA). Our methodology diverges from traditional model-based analyses, focusing instead on a parametrization technique that allows for direct extraction of LCDA information using both experimental and theoretical input. This approach facilitates analytical and numerical computations, aiming to provide unbiased observable estimates while managing theoretical uncertainties. The discussion includes the application to decay amplitudes, notably in the context of the B → γ ℓ ν decay.
