DESCRIPTION:Abstract: The origin and propagation of cosmic rays (CRs) is a 
 multi-disciplinary problem in which plasma (astro)physics plays a major ro
 le. Plasma processes are indeed determining how these charged particles ar
 e injected and accelerated at their astrophysical sources\, as well as the
  type of turbulence that CRs encounter as they propagate through different
  Galactic environments\; cosmic-ray propagation itself is defined by plasm
 a processes underlying their non-linear interaction with turbulence. More 
 than a century after their discovery\, our understanding of the processes 
 yielding cosmic rays and defining their journey through the Galaxy cannot 
 be considered satisfactory.In this talk\, I will discuss how the most-rece
 nt direct and indirect CR measurements challenge the naive picture of cosm
 ic-ray transport that is usually adopted by the astroparticle community\, 
 delving in what are the issues with a standard description of CR scatterin
 g based on Alfvénic fluctuations. I will also present recent results base
 d on different approaches that may solve some of the typical issues\, but 
 that simultaneously lead to new open questions.\nVortragende(r): Dr. Silvi
