	abstract = {This paper presents a numerical study of the interaction dynamics for the\&nbsp;solitary waves of a nonlinear Dirac field with scalar\&nbsp;self-interaction by using a fourth order accurate Runge-Kutta\&nbsp;discontinuous Galerkin (RKDG) method. Some new interaction\&nbsp;phenomena are observed: (a) a new quasi-stable long-lived\&nbsp;oscillating bound state from the binary collisions of\&nbsp;a single-humped soliton and a two-humped soliton;\&nbsp;(b) collapse in\&nbsp; binary and\&nbsp;ternary collisions; (c) strongly inelastic interaction\&nbsp; in\&nbsp;ternary collisions; and (d)\&nbsp; bound states with a short or long lifetime\&nbsp;from\&nbsp; ternary collisions.\&nbsp;},
