Description
We are studying the constraints obtained on transport and acceleration mechanisms of
galactic cosmic rays by using statistical tools, such as genetic algorithms or multimodal
nested sampling algorithms, linked with the propagation package GALPROP and recent
PAMELA data. Using only PAMELA data allows us to avoid inconsistencies between data
sets from different experiments, minimize uncertainties on the solar modulation
parameters, and have a complementary and precise data set on (anti-)matter as well as
primary and secondary nuclei over 3 orders of magnitude in energy. This allows us to
simultaneously place strong constraints on cosmic-ray propagation and acceleration
models. Preliminary results will be presented and discussed.
