Ballistic surfing acceleration physical mechanism Fermi / DSA (diffusive shock acc) non-physical mechanism Energy gain based on the Lorentz transformation between upstream and downstream reference frames. NON-PHYSICAL !
Spectral index predicted by BSA Spectral index predicted by Fermi/DSA incidentally correct
