Nucleon-nucleon short-range correlations (SRCs) induce a high momentum tail(HMT) in the single-nucleon momentum distribution function$n_{\v{k}}^J(\rho,\delta)$ in cold neutron-rich matter. While there are clearexperimental evidences that the SRC/HMT effects are different for neutrons andprotons and their strengths depend strongly on the isospin asymmetry of finitenuclei mostly based on electron-nucleus scattering experiments, much less isknown experimentally about the SRC/HMT effects in the dense neutron-richmatter. To facilitate further explorations of SRC/HMT effects in denseneutron-rich matter especially with heavy-ion reactions involving high-energyradioactive beams as well as multimessenger observations of neutron stars andtheir mergers, by incorporating the SRC-induced HMT in$n_{\v{k}}^J(\rho,\delta)$ into a Gogny-like energy density functional we studySRC/HMT effects on the equation of state (EOS) especially its symmetry energyterm and single-nucleon potential in the dense asymmetric nucleonic matter(ANM). Using a parametrization as a surrogate for the momentum-dependent kernelin the Gogny-like energy density functional (EDF) we derive analyticalexpressions for all components of the ANM EOS and their characteristics (e.g.,magnitude, slope and curvature as well as nucleon effective mass) at saturationdensity $\rho_0$ as well as the momentum-dependent single-nucleon opticalpotential in neutron-rich matter using parameters characterizing nuclearinteractions as well as the size, shape and isospin dependence of the HMT at$\rho_0$. Some consequences of the SRC/HMT effects on properties of neutronstars are also studied.
