Plots of input variables used for the ANN training

In this appendix, the plots of the distributions of the input variables used for the training of the ANN in the three considered signal regions, Figs.B.1 to B.12. As a recap, the used variables are listed in Table B.1. The plots show pre-fit distributions, normalised overlayed plots for signal and background to evaluate their separation, and finally the post-fit distributions. The latter show a good agreement between data and prediction a part of some statistical fluctuations.
