Abstract
In this work, we have achieved two main results. First, we have followed the method presented in Derome et al. 2019 to study the effect of cross-sections on the determination of propagation parameters. We generate and analyse mock data comparable to the B/C measurements performed by the AMS-02 experiment, using three benchmark models, BIG, SLIM, and QUAINT available in the literature. We show that detailed information of the nuclear cross-sections is essential to avoid biases in the analysis. Moreover, we have further constrained the propagation parameters using two additional bservables, namely the deuteron flux and the 2H/4He flux ratio, which are helpful to test the universality of CR propagation in the galaxy.
