We present new data on target fragmentation in muon-nucleus interactions at
(420 ± 45) GeV. A two-dimensional emission-angle -–
azimuthal-angle plot of target fragments does not indicate preferential emission
of target fragments. We also present an investigation on the two-particle
short-range angular correlation among the target fragments in azimuthal-angle
space. The experimental data have been compared with MC simulated events to
extract dynamical correlation. The data exhibit strong two-particle correlation
among target fragments in azimuthal space.
