  3. 14. Inclusive $B —> X_u\ell\nu$: Towards NNLO Extractions of $V_{ub}$
    Bernat Capdevila (Universitat de Barcelona, Institut de Ciències del Cosmos)
    12/06/2025, 15:20

    In this talk, I will present a short overview of inclusive $b\to u$ semileptonic decays. I will introduce the GGOU approach, one of the two most active frameworks for $V_{ub}$ extractions in recent years. And finally, I will outline our ongoing work on the extraction of NNLO corrections to the fully differential decay distribution.

  4. 16. Semileptonic B to D*/D** l nu decays at Belle II
    Markus Prim
    12/06/2025, 16:30

    In this talk, we will discuss the semileptonic B -> D l nu and B -> D* l nu measurements at Belle II, and explore additional observables that may offer useful insights beyond the standard ones.

  7. 7. Measurement of the differential distributions of $B_s^0\to D_s^{*-} \mu^+\nu_{\mu}$ decay with the LHCb detector
    Federico Manganella (Istituto Nazionale di Fisica Nucleare)

    This analysis aims to conduct a comprehensive study of the decay kinematics of the semileptonic decay \signal, with $D_s^{*-} \to D_s^- \gamma$ and $D_s^- \to K^+ K^- \pi^-$, using data collected by the LHCb experiment in Run 2. A first measurement of the form factors describing the $B_s^0$ meson semileptonic decay is provided, performing a four-dimensional binned fit in the space given by the...
