Uncertainties of Antiproton and Positron Spectra from B/C Data and mSUGRA Contributions for Clumpy Halos

A. M. Lionetto, A. Morselli, V. Zdravkovic

We have studied the variation of $e^{+}$ and $\bar{p}$ top of the atmosphere spectra due to the parameters uncertainties of the Milky Way geometry, propagation models and cross sectio…
