Semiclassical decay of strings with maximum angular momentum

  title={Semiclassical decay of strings with maximum angular momentum},
  author={Roberto Iengo and Jorge G. Russo},
A highly excited (closed or open) string state on the leading Regge trajectory can be represented by a rotating soliton solution. There is a semiclassical probability per unit cycle that this string can spontaneously break into two pieces. Here we find the resulting solutions for the outgoing two pieces, which describe two specific excited string states, and show that this semiclassical picture reproduces very accurately the features of the quantum calculation of decay in the large mass M limit… CONTINUE READING
