Gravitational Wave Bursts from Cosmic Superstring Reconnections
  We compute the gravitational waveform produced by cosmic superstring
reconnections. This is done by first constructing the superstring reconnection
trajectory, which closely resembles that of classical, instantaneous
reconnection but with the singularities smoothed out due to the string path
integral. We then evaluate the graviton vertex operator in this background to
obtain the burst amplitude. The result is compared to the detection threshold
for current and future gravitational wave detectors, finding that neither
bursts nor the stochastic background would be detectable by Advanced LIGO. This
disappointing but anticipated conclusion holds even for the most optimistic
values of the reconnection probability and loop sizes.
