Charm production: Constraint to transport models and charm diffusion coefficient with ALICE.

New measurements of D mesons with the ALICE detector, interpreted with theoretical models, can give additional information about the spatial diffusion coefficient, a characteristic of the QGP medium. The relevant ingredients to the models can be assessed by comparing the predictions with diverse measurements of charmed hadrons. This contribution discusses the comparison of measurements with a large set of predictions and the role of the different ingredients implemented in the theoretical models, as well as the conclusions about the spatial diffusion coefficient.
