Solitary waves in a Skyrmion-quark Lagrangian

Abstract

We investigate nontopological solitary wave solutions of a Skyrmion-quark Lagrangian. The quark wave functions are of the hedgehog type and the chiral angle corresponding to the classical pionic field goes to zero both at the origin and infinity. The Skyrme parameter is varied and nontopological solutions are found in a restricted range of values. The mass of the system is calculated and explicit solutions are shown for nodeless quark wave functions. The properties of the states are investigated.
