Abstract

We study the feasibility of a sterile neutrino search at the China Advanced Research Reactor by measuring ν_e survival probability with a baseline of less than 15 m. Both hydrogen and deuteron have been considered as potential targets. The sensitivity to sterile-to-regular neutrino mixing is investigated under the "3(active)+1(sterile)" framework. We find that the mixing parameter sin²(2θ₁₄) can be severely constrained by such measurement if the mass square difference Δm₁₄² is of the order of ∼1 eV².
