Session ID#: 44427

Session Description:
Solar flares are magnetic-field dominated systems associated with explosive magnetic energy release, particle acceleration, and high-energy emission. They are important sources of energetic electrons, protons, and minor ions observed in interplanetary space and may actively contribute to large solar energetic particle events. However, the question of how high-energy particles are energized, transport, and generate high-energy emission remain controversial and poorly understood. Modern ground based and spaceborne multiwavelength observations (radio, microwaves, EUV, soft and hard X-rays, and gamma-rays) have provided many details and new opportunities for studying the high-energy particles and emissions in flares. Meanwhile, new progresses from analytical theories and numerical models have been made on magnetic reconnection, turbulence, collisionless shocks, and associated particle acceleration, revealing a rich set of physical processes. This session invites observation, theory and modeling presentations toward solving the long-standing and renewed problem.
