In this study, we examine the orbital and epicyclic motions of test particles around a

rotating Einstein–Yang–Mills–Higgs (EYMH) black hole. The black hole model is

characterized by four parameters: the mass MMM, spin parameter aaa, the EYMH

parameter BBB, and a constant β\betaβ. We derive analytical expressions for the specific

energy, angular momentum, and the fundamental frequencies of radial, vertical, and

orbital oscillations near stable circular orbits. The stability of equatorial orbits is analyzed

through the effective potential approach, and relativistic precession effects such as

periastron and Lense-Thirring precessions are also evaluated. Our findings reveal that the

dynamical behavior of particles and the quasi-periodic oscillations (QPOs) are strongly

influenced by the model parameters. The study suggests that the predicted QPO

frequencies, particularly near the innermost stable circular orbits (ISCOs), could be

compared with observational X-ray data, offering a potential testbed for probing the

nature of EYMH black holes.
