| contents | The dark matter conundrum stands out as one of the central challenges to understand in both particle physics and cosmology. The ultralight axion-like particle (UALP) is an appealing dark matter candidate that can be searched for in neutrino oscillation experiments. In this work, we examine the interaction among neutrinos and a UALP; such interaction might induce violations of the Lorentz and $CPT$ symmetries. We assess the sensitivity to both the isotropic $CPT-$odd Standard Model Extension (SME) coefficients $(a_L)^T$ and effective neutrino-UALP couplings $\tilde{g}$ at the next-to-next generation neutrino oscillation experiment at the European Spallation Source (ESS). |
