The Q-balls have strictly finite radius. Their total energy is a power-like function of the conserved U(1) charge with the exponent equal to (d+2)/(d+3). In the cases d=1 and d=3 explicit analytic solutions are presented.9 pages, no figuresHigh Energy Physics - TheoryAstrophysicsHigh Energy Physics - PhenomenologyPattern Formation and Solitonstext
