arXiv:1703.05772 [pdf, other] Newly-Discovered Anomalies in Galactic Cosmic Rays: Time for Exotic Scenarios? Mikhail Malkov Comments: Cosmic Rays beyond the Standard Model, San Vito, 2016, this http URL, conference paper Subjects: High Energy Astrophysical Phenomena (astro-ph.HE) Recent observations of galactic cosmic rays (CR) in the 1-500 GeV energy range have revealed striking deviations from what deemed "standard." The anomalies cut across hadronic and leptonic CRs. I discuss findings that challenge physical mechanisms long held responsible for the CR production in galactic supernova remnants (SNR). I also consider some new physics of particle acceleration in SNR shocks that is not part of conventional models but may explain the anomalies. However, a possible 20-30\% excess remains unaccounted for in the e+/e+ ratio over the range of a few 100 GeV. If not explained by future models, it suggests an additional source of positrons such as a dark matter decay/annihilation or pulsar contribution. Earlier efforts to explain both the e+/e− and p/He anomalies with the "standard" models by adjusting the SNR environmental parameters and multiple sources are critically assessed. Just as the title says, Is Dark Mater expected to be in the 100GeV range? Thanks for replies.
