| contents | We consider an atlas of leptophilic models with non-universal charges that combine the quantum numbers \((L_e - L_μ)\) and \((L_μ - L_τ)\) in various realizations. We explore diverse manifestations of the atlas to understand their impact on explaining the muon \((g-2)_μ\) anomaly, as well as the origin of self-interacting dark matter, which serves as a feasible explanation for the small-scale challenges of cold dark matter. We found that a single vector gauge boson with mass range of $\sim 10~\mathrm{MeV}$ and non-universal couplings as indicated successfully mediates interactions in the fermion and dark matter sectors in such a way that $(g-2)_μ$ additional contribution agrees with experimental constraints and the self-interacting dark matter fluid behaves as suggested by observations at different astrophysical length scales. Furthermore, the model requires a dark matter candidate within $10-100~ \mathrm{GeV}$ order mass and a strong dark coupling ($g_χ \sim 0.3$, much stronger than the lepton's couplings $g'_l \lesssim 10^{-4}$) to be a successful scenario to unravel astrophysical small scale problems. |
