Description
In this talk, I will present a short overview of inclusive $b\to u$ semileptonic decays, focusing on the current status of the BLNP and GGOU approaches—the two most active frameworks for $V_{ub}$ extractions in recent years. I will delve deeper into the GGOU approach, highlighting our work and status on the NNVub framework, which utilises neural networks for parametrising the required shape functions. I will very briefly discuss the calculation of perturbative power-suppressed corrections. And finally, I will outline our ongoing work on the extraction of NNLO corrections to the fully differential decay distribution.
