Abstract

We revisit neutrino oscillations in matter considering the open quantum system framework, which allows to introduce possible decoherence effects generated by New Physics in a phenomenological manner. We assume that the decoherence parameters yid may depend on the neutrino energy, as gamma(ij) = gamma(0)(ij) (E/GeV)(n) (n = 0, +/- 1, +/- 2). The case of non-uniform matter is studied in detail and, in particular, we develop a consistent formalism to study the nonadiabatic case dividing the matter profile into an arbitrary number of layers of constant densities. This formalism is then applied to explore the sensitivity of IceCube and DeepCore to this type of effects. Our study is the first atmospheric neutrino analysis where a consistent treatment of the matter effects in the three-neutrino case is performed in presence of decoherence. We show that matter effects are indeed extremely relevant in this context. We find that IceCube is able to considerably improve over current bounds in the solar sector (gamma(21)) and in the atmospheric sector (gamma(31) and gamma(32)) for n = 0, 1, 2 and, in particular, by several orders of magnitude (between 3 and 9) for the n = 1, 2 cases. For n = 0 we find gamma(32), gamma(31) < 4.0 x 10(-24) (1.3 x 10(-24)) GeV and gamma(21) < 1.3 x 10(-24) (4.1 x 10(-24)) GeV at the 95% CL, for normal (inverted) mass ordering.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal EUROPEAN PHYSICAL JOURNAL C 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 7/29, thus managing to position itself as a Q1 (Primer Cuartil), in the category Physics, Particles & Fields.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 1.5. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 14, 2024)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 1.86 (source consulted: FECYT Feb 2024)
  • Field Citation Ratio (FCR) from Dimensions: 16.81 (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: 28
  • Scopus: 39
  • OpenCitations: 36

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: 9.
  • 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: 9 (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: 1.75.
  • The number of mentions on the social network X (formerly Twitter): 4 (Altmetric).
