For various plasma applications the so-called (non-relativistic) κ -distribution is widely used to reproduce and interpret the suprathermal particle populations exhibiting a power-law distribution in velocity or energy. Despite its reputation the standard κ -distribution as a concept is still disputable, mainly due to the velocity moments M l which make a macroscopic characterization possible, but whose existence is restricted only to low orders . In fact, the definition of the κ -distribution itself is conditioned by the existence of the moment of order l = 2 ( i.e. , kinetic temperature) satisfied only for . In order to resolve these critical limitations we introduce the regularized κ -distribution with non-diverging moments. For the evaluation of all velocity moments a general analytical expression is provided enabling a significant step towards a macroscopic (fluid-like) description of space plasmas, and, in general, any system of κ -distributed particles.
