Description
Charmonium production has been modeled using NRQCD factorization. It is necessary to test the theoretical precision of the factorization formula along with the estimation of the short-distance dynamics through the fitting with the experimental data. The present talk presents a brief review of the literature's theoretical predictions of charmonium production applied to the decay mode $B\rightarrow H(c\bar{c}) X$ and shows the fitting of the long-distance matrix elements with experimental data considering simultaneously an approach to estimate the theoretical uncertainties thought variating the NRQCD and QCD renormalization scales.
