摘要
The full data set of the Daya Bay reactor neutrino experiment is used to
probe the effect of the charged current non-standard interactions (CC-NSI) on
neutrino oscillation experiments. Two different approaches are applied and
constraints on the corresponding CC-NSI parameters are obtained with the
neutrino flux taken from the Huber-Mueller model with a 5% uncertainty. Both
approaches are performed with the analytical expressions of the effective
survival probability valid up to all orders in the CC-NSI parameters. For the
quantum mechanics-based approach (QM-NSI), the constraints on the CC-NSI
parameters ϵ_eα and ϵ_eα^s are extracted with
and without the assumption that the effects of the new physics are the same in
the production and detection processes, respectively. The approach based on the
effective field theory (EFT-NSI) deals with four types of CC-NSI represented by
the parameters [ε_X]_eα. For both approaches, the results
for the CC-NSI parameters are shown for cases with various fixed values of the
CC-NSI and the Dirac CP-violating phases, and when they are allowed to vary
freely. We find that constraints on the QM-NSI parameters ϵ_eα
and ϵ_eα^s from the Daya Bay experiment alone can reach the
order 𝒪(0.01) for the former and 𝒪(0.1) for the latter,
while for EFT-NSI parameters [ε_X]_eα, we obtain
𝒪(0.1) for both cases.
