Scotogenic model with non-invertible symmetry
In the present work, the scotogenic model is constructed applying non-invertible $$Z_M$$ symmetries. The stability of dark matter and the scotogenic structure of the neutrino mass matrix is achieved via a novel application of non-invertible symmetry. The Scotogenic model with non-invertible symmetry is given with minimalistic content giving a one-zero structure of the neutrino mass matrix, and numerical analysis of the lepton mixing angles and physics are presented. Other relevant constraints are also studied.- 17 September 2026

The neutrino mass matrix texture is achieved by means of $T^{\prime}$ flavor discrete symmetry extension of the Standard Model gauge group. The model realizing the neutrino mixing pattern consists of a combination of type-I and II seesaw mechanisms in the minimal possible extension of the Standard Model. Stringent predictions are obtained for normal and inverted neutrino mass orderings. Some important predictions include $α_2 \approx 2π$ (best fit), $m_{\text{lightest}} \approx 3 - 4 \times 10^{-4}\,\text{eV}$, and $m_{ee}^{0νββ} \approx 3 \times 10^{-3}\,\text{eV}$ for normal neutrino mass ordering; $110^\circ < α_1 < 170^\circ$, $40(220)^\circ < α_2 < 60(240)^\circ$, $240^\circ < δ_{\text{Dirac}} < 310^\circ$, and $m_{\text{lightest}} \approx 2 \times 10^{-5} - 7 \times 10^{-3}\,\text{eV}$ for inverted neutrino mass ordering.Open AccessSeesaw-I and II Hybrid $T^{\prime}$ Symmetric Neutrino Masses with Mass Selection RuleThe present manuscript studies a recently proposed new neutrino mixing scheme with a neutrino mass selection rule, $m_ν^{13} + m_ν^{22} + m_ν^{31} = 0$, among a neutrino mass matrix elements.

Pathways to proton's stability via naturally small neutrino masses
In the present work, the connection between the smallness of the neutrino masses and the stability of the proton is studied. We analyze this connection from different perspectives: the smallness of neutrino mass and the proton stability originate from the same source, small neutrino masses lead to a long lived proton, and the smallness of the proton decay width as a cause of the naturally small neutrino masses. All the schemes are studied in detail and UV realizations are given. We discuss advantages of each scheme and outline further investigation directions.

Extended scotogenic model of neutrino mass and proton decay
The current article presents an extension of the classical scotogenic neutrino mass paradigm, where the three issues in particle physics: dark matter, smallness of neutrino mass, and stability of the proton are interconnected. The scenario encompasses the neutrino mass as well as the proton decay as a consequence of an existence of the dark matter. The study successfully achieves the correlation between the naturally small neutrino masses and naturally long proton lifetime in the present paradigm. Furthermore, all relevant cosmological, collider, and flavor physics constraints are incorporated in the detailed analysis. The scotogenic fermionic dark matter with the mass in the range from 100 GeV to 10 TeV successfully satisfies all relevant constraints. The valid range of 2.51 × 10 − 5 < λ < 2 × 10 − 3 is obtained for the 2HDM λ coupling. We give a brief discussion, as well as outline some of the future prospects.

Neutrino mass sum rules from modular symmetryModular symmetries offer a dynamic approach to understanding the flavor structure of leptonic mixing. Using the modular flavor symmetry integrated in a type-II seesaw, we propose a simple and minimalistic model that restricts the neutrino oscillation parameter space and, most importantly, introduces a sum rule in the physical neutrino masses. When combined with the mass squared differences observed in neutrino oscillations, this sum rule determines the absolute neutrino mass scale. This has significant implications for cosmology, neutrinoless double beta decay experiments, and direct neutrino mass measurements. In particular, the model predicts for both normal and inverted ordering, and thus can be fully probed by the current generation of cosmological probes in the upcoming years.- 20 February 2024

In the novel scenario all Cabibbo-Kobayashi-Maskawa mixing angles and quark masses, nine observable quantities in total, are predicted within 1$-$3 standard deviations of the experimental values with a minimum number of input parameters. The present work provides the thorough numerical analysis and correlations between input parameters and predicted quantities. $\chi^2\approx 0.67$ with $\forall\sigma<0.61$ corresponds to the best global fit benchmark point. Benefits of the new parameterization and future prospects are discussed as well.Open AccessDemocratic parameterization and analysis for 331 model as a subgroup of $SU(6)$A democratic parameterization is introduced for $SU(3)_C\otimes SU(3)_L\otimes U(1)_X$ extension of the Standard Model, which is inspired by $SU(6)$ symmetry.

New parameterization and analysis for E6 inspired 331 model
We present a new parameterization for $E_6$ inspired $SU(3)_C\times SU(3)_L\times U(1)_X$ extension of the Standard Model. New setup predicts all Cabibbo-Kobayashi-Maskawa mixing angles and quark masses, total of nine observable variables, within 1-3 standard deviations of the experimental values with a minimum number of input parameters. A detailed numerical analysis and correlations between input parameters and predicted quantities are presented. The best global fit benchmark point corresponds to $\chi^2\approx 0.7$ with $\forall\sigma<0.6$. Advantages of the new parameterization and future prospects are discussed as well.Open AccessNew parameterization and analysis for E6 inspired 331 model
