Angular Analysis of $B \to D^{*}\ell \barν_{\ell}$ from Lattice and Experiment: $|V_{cb}|$ and New Physics Constraints / Bordone, Marzia (U. Mainz, PRISMA) ; Heald, Ollie (Southampton U.) ; Jüttner, Andreas (Southampton U. ; CERN)
We present a combined angular analysis within and beyond the Standard Model (SM) of experimental measurements for the $B \to D^{*}\ell \barν_{\ell}$ angular coefficients provided by the Belle collaboration, together with lattice-calculated hadronic form-factor data from the HPQCD, JLQCD, and FNAL/MILC collaborations.

We renormalise (and improve) the flavour non-singlet axial current, pseudo-scalar density, vector current and tensor current, as well as quark masses, in O(a) improved lattice QCD with three massless flavours and lattice spacings down to 0.01 fm. [...]

In this contribution we discuss state-of-the-art hadron-level predictions for the deep-inelastic scattering process at next-to-leading-order precision for several multiplicities, consistently merged in one sample. [...]
