Abstract

We discuss the possibility to explain the anomalies in short-baseline neutrino oscillation experiments in terms of sterile neutrinos. We work in a 3+1 framework and pay special attention to recent new data from reactor experiments, IceCube and MINOS+. We find that results from the DANSS and NEOS reactor experiments support the sterile neutrino explanation of the reactor anomaly, based on an analysis that relies solely on the relative comparison of measured reactor spectra. Global data from the nu(e) disappearance channel favour sterile neutrino oscillations at the 3 sigma level with Delta m(41)(2) approximate to 1.3 eV(2) and vertical bar U-e4 vertical bar approximate to 0.1, even without any assumptions on predicted reactor fluxes. In contrast, the anomalies. in the nu(e) appearance channel (dominated by LSND) are in strong tension with improved bounds on nu(mu) disappearance, mostly driven by MINOS+ and IceCube. Under the sterile neutrino oscillation hypothesis, the p-value for those data sets being consistent is less than 2.6 x 10(-6). Therefore, an explanation of the LSND anomaly in terms of sterile neutrino oscillations in the 3+1 scenario is excluded at the 4.7 sigma level. This result is robust with respect to variations in the analysis and used data, in particular it depends neither on the theoretically predicted reactor neutrino fluxes, nor on constraints from any single experiment. Irrespective of the anomalies, we provide updated constraints on the allowed mixing strengths vertical bar U-alpha 4 vertical bar (alpha = e, mu, tau) of active neutrinos with a fourth neutrino mass state in the eV range.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Journal Of High Energy Physics due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2018, it was in position 5/29, thus managing to position itself as a Q1 (Primer Cuartil), in the category Physics, Particles & Fields.

This publication has been distinguished as a “Highly Cited Paper” by the agencies WoS (ESI, Clarivate) and ESI (Clarivate), meaning that it ranks within the top 1% of the most cited articles in its thematic field during the year of its publication. In terms of the observed impact of the contribution, this work is considered one of the most influential worldwide, as it is recognized as highly cited. (source consulted: ESI Nov 14, 2024)

And this is evidenced by the extremely high normalized impacts through some of the main indicators of this type, which, although dynamic over time and dependent on the set of average global citations at the time of calculation, already indicate that they are well above the average in different agencies:

  • Normalization of citations relative to the expected citation rate (ESI) by the Clarivate agency: 13.92 (source consulted: ESI Nov 14, 2024)
  • Weighted Average of Normalized Impact by the Scopus agency: 17.79 (source consulted: FECYT Feb 2024)
  • Field Citation Ratio (FCR) from Dimensions: 113.49 (source consulted: Dimensions Jun 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-06-17, the following number of citations:

  • WoS: 259
  • Scopus: 274
  • OpenCitations: 248

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-06-17:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 38.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 38 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 41.6.
  • The number of mentions on the social network X (formerly Twitter): 29 (Altmetric).
  • The number of mentions in news outlets: 2 (Altmetric).
