Abstract:
Giulio Barni will present "Q-balls: Existence and Stability from Coleman to Now" basada en “Q-balls”, de Sidney R. Coleman ( Nucl.Phys.B 262 (1985) 2, 263):
Q-balls are non-topological solitons that arise in theories with a conserved global (or local) charge, first introduced by Coleman in the 1980s. Since their discovery, these objects have found applications in a wide range of physical contexts, from supersymmetric theories and baryogenesis to dark matter and astrophysics. In this talk, I will review the fundamental principles behind Q-ball existence and stability, highlighting key theoretical developments from Coleman's original work to modern advancements. I will discuss the conditions required for their formation and stability, their role in cosmology, and if time permits some recent progress in understanding their dynamics and their use.
