Query: Constrained Dynamics of an Anomalous $(g/neq 2)$ Relativistic Spinning
  Particle in Electromagnetic Background   In this paper we have considered the dynamics of an anomalous ($g\neq 2$)
charged relativistic spinning particle in the presence of an external
electromagnetic field. The constraint analysis is done and the complete set of
Dirac brackets are provided that generate the canonical Lorentz algebra and
dynamics through Hamiltonian equations of motion. The spin-induced effective
curvature of spacetime and its possible connection with Analogue Gravity models
are commented upon.
