Is the Z^+(4430) a radially excited state of D_s?

Takayuki Matsuki, Toshiyuki Morii, Kazutaka Sudoh

We present the interpretation that the recently discovered Z^+(4430) by the Belle Collaboration can be a radial excitation of the cs-bar state. We give an explicit cs-bar candidate…

Thermalization of Color Gauge Fields in High Energy Heavy Ion Collisions

Aiichi Iwazaki

We discuss quantum mechanical decay of color magnetic field generated initially at high energy heavy ion collisions. It is caused by Nielsen-Olesen unstable modes and is accomplish…

Spontaneous Breakdown of U(1) symmetry in DLCQ without Zero Mode

Aiichi Iwazaki

We show that the spontaneous breakdown of U(1) symmetry in a Higgs model can be described in discretized light cone formulation even by neglecting zero mode. We obtain correctly th…
