| What can we really learn from positron flux 'anomalies'? (2009) | |||||||||
Abstract | |||||||||
| We present a critical analysis of the observational constraints on, and of the theoretical modeling of, aspects of cosmic ray (CR) generation and propagation in the Galaxy, which are relevant for the interpretation of recent positron and anti-proton measurements. We give simple, analytic, model independent expressions for the secondary pbar flux, and an upper limit for the secondary e+ flux, obtained by neglecting e+ radiative losses, e+/(e+ + e-).
