Show affiliationsThe Hosotani mechanism (1983) in the closed-string theory with current algebra symmetry is described by the (old covariant) operator method. The author compares the gauge symmetry breaking mechanism in a string theory which contains SU(2) symmetry originated from current algebra with the one in an equivalent compactified closed-string theory. The author also investigates the difference between the Hosotani mechanism and the Higgs mechanism in closed-string theories by calculation of a four-point amplitude of 'Higgs' bosons at tree level.
