Cosmological effects of decaying cosmic string loops with TeV scale
  width
  In supersymmetric theories, cosmic strings produced in the early Universe
often have a width of TeV scale, while the tension is much larger. In a scaling
regime, an infinite cosmic string releases significant fraction of its energy
in the form of string loops. These thick string loops lose their energies
efficiently by particle emissions, and hence it may have effects on
cosmological observations. We study cosmological implications of string loops
with TeV scale width in detail and derive constraints on the tension of the
string. Implications on future gravitational wave detectors are also discussed.
