Özet

We present results over an 11-year Solar cycle of cosmic antiprotons based on 1.1 x 10(6) events in the rigidity range from 1.00 to 41.9 GV. The (p) over bar fluxes exhibit distinct properties. The magnitude of the (p) over bar flux temporal variation is significantly smaller than those of p, e(-), and e(+). A hysteresis between the (p) over bar fluxes and the p fluxes is observed, whereas the (p) over bar and e(-) fluxes show a linear correlation. With a model-independent analysis, we found a universal relation between the shape of the rigidity spectrum and the magnitude of flux temporal variation over an 11-year Solar cycle for both positively and negatively charged particles. The simultaneous results on (p) over bar and p, e(-), and e(+) provide unique information for understanding particle transport in the Solar System as a function of mass, charge, and spectral shape.
