“…Flux measurements by the Daya Bay experiment have subsequently validated the existence of this flux discrepancy [23]. Further, results by the θ 13 reactor experiments have uncovered a discrepancy in the measured antineutrino spectrum with respect to beta-converted predictions, with particular focus on the 5-7 MeV region of antineutrino energy [10,23,24].…”

Prospects for improved understanding of isotopic reactor antineutrino fluxes

Predictions of antineutrino fluxes produced by fission isotopes in a nuclear reactor have recently received increased scrutiny due to observed differences in predicted and measured inverse beta decay (IBD) yields, referred to as the "reactor antineutrino flux anomaly." In this paper, global fits are applied to existing IBD yield measurements to produce constraints on antineutrino production by individual plutonium and uranium fission isotopes. We find that fits including measurements from highly 235 U-enriched cores and fits including Daya Bay's new fuel evolution result produce discrepant bestfit IBD yields for 235 U and 239Pu. This discrepancy can be alleviated in a global analysis of all data sets through simultaneous fitting of 239 Pu, 235 U, and 238 U yields. The measured IBD yield of 238 U in this analysis is ð7.02 AE 1.65Þ × 10 −43 cm 2 =fission, nearly two standard deviations below existing predictions. Future hypothetical IBD yield measurements by short-baseline reactor experiments are examined to determine their possible impact on the global understanding of isotopic IBD yields. It is found that future improved short-baseline IBD yield measurements at both high-enriched and low-enriched cores can significantly improve constraints for 235 U, 238 U, and 239 Pu, providing comparable or superior precision to existing conversion-and summation-based antineutrino flux predictions. Systematic and experimental requirements for these future measurements are also investigated.

The RENO experiment reports more precisely measured values of θ13 and |∆m 2 ee | using ∼2 200 live days of data. The amplitude and frequency of reactor electron antineutrino (νe) oscillation are measured by comparing the prompt signal spectra obtained from two identical near and far detectors. In the period between August 2011 and February 2018, the far (near) detector observed 103 212 (850 666) νe candidate events with a background fraction of 4.8% (2.0%). A clear energy and baseline dependent disappearance of reactor νe is observed in the deficit of the measured number of νe. Based on the measured far-to-near ratio of prompt spectra, we obtain sin 2 2θ13 = 0.0896 ± 0.0048(stat) ± 0.0047(syst) and |∆m 2 ee | = [2.68 ± 0.12(stat) ± 0.07(syst)] × 10 −3 eV 2 .

“…Among others: whether the neutrinos are Dirac or Marjorana fermions; the absolute neutrino mass scale; the posible sources of Charge-Parity [CP] violation [CPV] in leptons. Nowadays, answers to these questions are being searched by means of the experimental results concerning KamLAND reactor neutrinos [3][4][5], in each one of the current high-statistics Short Base-Line (SBL) reactor neutrino experiments RENO [6,7], Double Chooz [8] and Daya Bay [9]. Also, one of the most interesting effects related to the neutrino oscillation in matter is, that these periodic transformations of neutrinos from one flavor to another, can induce a fake CP violating effect.…”

Lepton CP violation in a ν2HDM with flavor

et al. 2018

In this work we propose an extension to the Standard Model in which we consider the model 2HDM type-III plus massive neutrinos and the horizontal flavor symmetry S3 (ν2HDM⊗S3). In the above framework and with the explicit breaking of flavor symmetry S3, the Yukawa matrices in the flavor adapted basis are represented by means of a matrix with two texture zeroes. Also, the active neutrinos are considered as Majorana particles and their masses are generated through type-I seesaw mechanism. The unitary matrices that diagonalize the mass matrices, as well as the flavor mixing matrices, are expressed in terms of fermion mass ratios. Consequently, in the mass basis the entries of the Yukawa matrices naturally acquire the form of the so-called Cheng-Sher ansatz. For the leptonic sector of ν2HDM⊗S3, we compare, through a χ 2 likelihood test, the theoretical expressions of the flavor mixing angles with the masses and flavor mixing leptons current experimental data.The results obtained in this χ 2 analysis are in very good agreement with the current experimental data. We also obtained an allowed value ranges for the "Dirac-like" phase factor, as well as for the two Majorana phase factors. Furthermore, we study the phenomenological implications of these numerical values of the CP-violation phases on the neutrinoless double beta decay, and for Long Base-Line neutrino oscillation experiments such as T2K, NOνA, and DUNE.the Yukawa matrix entries and the parameters used to compute the decay widths and cross section, without losing the terms proportional to the light fermion masses. Specifically, considering a zero texture Yukawa matrix, one obtains the Cheng-Sher ansatz for flavor mix couplings, widely used in literature, where flavored couplings are considered proportional to the involved fermion masses [31].The matter content in the 2HDM is divided among the quarks and leptons sectors. In turn these sectors are subdivided in two sectors, the up-and down-type for quarks sector, while charged leptons and neutrinos for the leptons sector. The fermions in each one of these subsectors are analogous each other, because they have completely identical couplings to all gauge bosons, although their mass values are not the same. Therefore, before of the spontaneous symmetry breaking (SSB), the Yukawa Lagrangian in the above subsectors is invariant under permutations of flavor indices. In other words, each one of these subsectors is invariant under the action of a S 3 symmetry group. This symmetry group has only three irreducible representations that correspond to two singlets and a doublet [32,33].On the other hand, obtained from the experimental data, the mass spectrum for Dirac fermions obeys the following
