Description
Using a renormalization-inspired perturbation expansion we show that oscillons in a generic field theory in (1+1)-dimensions arise as dressed $Q$-balls of a universal complex field theory. This theory is very close to the integrable complex sine-Gordon model which possesses exact multi-$Q$-balls. We show that excited oscillons, with their characteristic amplitude modulations, are two-oscillons bound states generated from a two $Q$-ball solution.
