We make predictions for the exclusive semileptonic and the non-leptonic decay widths of the B_c meson. We evaluate the B_c semileptonic form factors for different decay channels in a relativistic model, and use factorization to obtain the non-leptonic decay widths.

$|V_{ub}|$ determination and testing of lepton flavour universality in semileptonic $B_c \rightarrow D^{(\ast)}$ decays
A three-point QCD sum-rule calculation of B_c to D^(*) form factors supports a new |Vub| extraction channel and predicts lepton universality ratios R_c(D^0) = 0.64 +/- 0.05 and R_c(D*) = 0.55 +/- 0.05.

$B_c$ meson decays into $S$-wave charmonium plus light meson pairs in the perturbative QCD approach
pQCD calculations predict ~90% longitudinal polarization in B_c to J/psi or psi(2S) plus rho or K* mediated light meson pairs, with one branching ratio ratio matching LHCb at 2.67 vs 2.80.

Unravelling theoretical challenges in understanding $B_c$ meson decay
The paper presents new RIQ-model predictions for B_c decay ratios (R_D/D*, R_eta_c/J/psi, and tau/mu leptonic ratios) with no derivation or error bars.
