The traditional approach to fixing the parameters of the Skyrme model requires the energy of a spinning skyrmion to reproduce the nucleon and delta masses. The standard Skyrme parameters, which are used almost exclusively, fix the pion mass to its ex... Read More about Spinning Skyrmions and the Skyrme parameters..

We present numerical evidence that suggests the introduction of a nonzero pion mass might dramatically affect the structure of minimal energy skyrmions. It appears that the shell-like skyrmions which are the minima when the pions are massless can fai... Read More about Skyrmions and the pion mass..

We show that skyrmions with massless pions in hyperbolic space provide a good approximation to skyrmions with massive pions in Euclidean space, for a particular relationship between the pion mass and the curvature of hyperbolic space. Using this resu... Read More about Skyrmions, instantons, mass and curvature..
