| dc.description | 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 sections. We have used the B/C data and Galprop code for propagation analysis. We have also derived the uncertainty bands for subFe/Fe ratio, H and He. Finally we have considered a neutralino induced component in the mSUGRA framework. We conclude that even in the case of diffusion convection model for the standard propagation, where secondary spectra gives a good fit of the data, SUSY contribution can not be excluded up to now due to the overall uncertainties. | |
