Cosmic Ray Origin - Beyond the Standard Models

Given the success of the first meeting of "Cosmic Ray Origin - Beyond the Standard Models" (CRBTSM 2014), it was decided to hold a second meeting of this international conference. In these introductory remarks, we rehearse the motivation for reconsidering the origin(s) of cosmic rays (CR). We argue that the standard model, in which the majority of Galactic cosmic rays are produced through Diffusive Shock Acceleration (DSA) in SuperNova Remnants (SNR), is insufficient to account for recent observations. Some alternative scenarios are introduced and examined.
