Regular maintenance of the system takes place during the next weeks. This causes the service to be eventually down during the evening, night or weekends. This is related to CEST time zone.

Weak Decays and Matrix Elements
Poster Presentation

This poster reviews the recent HPQCD calcuation of $B_c^+ \to D^0 \ell^+ \nu$ and $B_c^+ \to D_s^+ \ell^+ \ell^- (\nu \bar\nu)$ form factors [Phys. Rev. D 105, 014503 (2022), arXiv:2108.11242]. We comment on prospects for experimental measurement of $B_c^+ \to D^0 \ell^+ \nu$ and implications for CKM matrix elements.
