WAVE-PACKET COLLISIONS IN YANG-MILLS-HIGGS THEORY

We present numerical simulations of colliding wave packets in spontane ously broken SU(2) Yang-Mills-Higgs theory. Compared with pure Yang-Mi lls theory, introducing the Higgs field leads to new aspects in the dy namics of the system. The evolution of the gauge field and the Higgs f ield is investigated as a function of the amplitude of the wave packet s and of the mass ratio of the Higgs boson and the gauge boson. We fin d regions in our parameter space in which initial wave packets scatter into final configurations with dramatically different momentum distri butions.
