On the Collision of Cosmic Superstrings
E. J. Copeland, H. Firouzjahi, T. W. B. Kibble +1
We study the formation of three-string junctions between (p,q)-cosmic superstrings, and collisions between such strings and show that kinematic constraints analogous to those found…
No resonant tunneling in standard scalar quantum field theory
Edmund J. Copeland, Antonio Padilla, Paul M. Saffin
We investigate the nature of resonant tunneling in Quantum Field Theory. Following the pioneering work of Banks, Bender and Wu, we describe quantum field theory in terms of infinit…
Dynamical solutions of warped six dimensional supergravity
Edmund J. Copeland, Osamu Seto
We derive a new class of exact time dependent solutions in a warped six dimensional supergravity model. Under the assumptions we make for the form of the underlying moduli fields,…
