A new approach to instanton calculations in the O(3) nonlinear sigma model
Jeroen Snippe, Pierre van Baal
We construct all instantons in the \nlsig\ on a cylindrical space-time, known not to exist on a finite time interval. The scale parameter, , is related to the boundary condition…

Tunneling Through Sphalerons: The O(3) Sigma-Model on a Cylinder
Jeroen Snippe
We construct all instantons for the \nlsig\ on a cylinder, known not to exist on a finite time interval. We show that the widest instantons go through sphalerons. A re-interpretati…
