Query: Bosonic (meta)stabilization of cosmic string loops   We consider the possibility of a bosonic (meta)stabilization of a cosmic
gauge string loop due to the presence of a gas of low mass bosonic particles
which become trapped within the string core. This boson gas exerts a pressure
which tends to counteract the string tension, allowing a circular string loop
to find a finite equilibrium radius, provided that gas particles do not escape
the string core. However, high energy bosons do escape, and consequently the
loop shrinks and the temperature rises. Estimates indicate that the bosonic
stabilization mechanism is ineffective, and the loop is unstable against decay.
