  Q-balls are non-topological solitons arising in scalar field theories.
Solutions for rotating Q-balls (and the related boson stars) have been shown to
exist when the angular momentum is equal to an integer multiple of the Q-ball
charge $Q$. Here we consider the possibility of classically long-lived
metastable rotating Q-balls with small angular momentum, even for large charge,
for all scalar theories that support non-rotating Q-balls. This is relevant for
rotating extensions of Q-balls and related solitons such as boson stars as it
impacts their cosmological phenomenology.
