    We determine the impact of the θ angle and axion physics on the near conformal dynamics of the large-charge baryon sector of SU(2) gauge theories with Nf fermions in the fundamental representation. We employ an effective approach featuring Goldstone and dilaton degrees of freedom augmented by the topological terms in the theory. We investigate how different dilaton potentials, including the ones for which a systematic counting scheme can be established, affect the results. Via state-operator correspondence we compute the corrections to the would-be conformal dimensions of the lowest large-charge operators as a function of the θ term and dilaton potential.
