“…The LSND [15] and MiniBooNE [16,17] experiments observed excesses of electron (anti-)neutrino events in the muon (anti-)neutrino beams, which could be interpreted as sterile neutrino oscillation with |∆m 2 | ∼ 1 eV 2 . However, these results are in tension [18][19][20][21] with the limits derived from other appearance [22][23][24][25] or disappearance searches [26][27][28][29][30][31][32][33][34][35][36]. Moreover, a reanalysis of the measured vs. predicted electron antineutrino events from previous reactor experiments has revealed a deficit of about 6% [37,38].…”

A search for light sterile neutrino mixing was performed with the first 217 days of data from the Daya Bay Reactor Antineutrino Experiment. The experiment's unique configuration of multiple baselines from six 2.9 GW th nuclear reactors to six antineutrino detectors deployed in two near (effective baselines 512 m and 561 m) and one far (1579 m) underground experimental halls makes it possible to test for oscillations to a fourth (sterile) neutrino in the 10 −3 eV 2 < |∆m 2 41 | < 0.3 eV 2 range. The relative spectral distortion due to electron antineutrino disappearance was found to be consistent with that of the three-flavor oscillation model. The derived limits on sin 2 2θ14 cover the 10 −3 eV 2 |∆m 2 41 | 0.1 eV 2 region, which was largely unexplored.

Minimal dark energy: key to sterile neutrino and Hubble constant tensions?

Minimal dark energy models, described by the same number of free parameters of the standard cosmological model with cold dark matter plus a cosmological constant to parameterize the dark energy component, constitute very appealing scenarios which may solve long-standing, pending tensions. On the one hand, they alleviate significantly the tension between cosmological observations and the presence of one sterile neutrino motivated by the short-baseline anomalies: for some cases, the 95%CL cosmological bound on the mass of a fully thermalized fourth sterile neutrino is relaxed to ms < 1.3 eV. Interestingly, this limit is in agreement with the observations at short-baseline experiments. On the other hand, the Hubble tension is satisfactorily solved in almost all the minimal dark energy schemes explored here. These phenomenological scenarios may therefore shed light on differences arising from near and far universe probes, and also on discrepancies between cosmological and laboratory sterile neutrino searches.
