  The glueball dark matter, in the pure SU(N) Yang-Mills theory, engenders dark
SU(N) stars that comprise self-gravitating compact configurations of scalar
glueball fields. Corrections to the highest frequency of gravitational wave
radiation emitted by dark SU(N) star mergers on a fluid brane with variable
tension, implemented by the minimal geometric deformation, are derived and
their consequences analysed. Hence, dark SU(N) stars mergers on a fluid
brane-world are shown to be better detectable by the LIGO and the eLISA
experiments.
