Scalar NSI: a unique tool for constraining absolute neutrino masses via neutrino oscillations
European Physical Journal C: Particles and FieldsIn the standard interaction scenario, a direct measurement of absolute neutrino masses via neutrino oscillations is not feasible, as the oscillations depend only on the mass-squared differences.

Annalen der Physik, Volume 538, Issue 1, January 2026.The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Extrinsic and intrinsic CPT asymmetries in neutrino oscillations
Nuclear Physics B, 2015 We reconsider the extrinsic and possible intrinsic CPT violation in neutrino oscillations, and point out an identity, i.e., AαβCP=AβαCPT+AαβT, among the CP, T, and CPT asymmetries in oscillations.

Majorana neutrino masses and neutrino oscillations [PDF]
Physical Review D, 2001 We examine some patterns of Majorana neutrino mass matrix which is compatible with the phenomenological lepton flavor mixing matrix and non-observation of neutrinoless double beta decay. Imposing $(M_ν)_{ee}=0$ for the Majorana neutrino mass matrix in the leading order, we obtain a relationship between the solar mixing angle and the neutrino masses ...

A Renormalizable Neutrino Mass Model With (Z2 × Z4)⋊Z2(II) Symmetry
Advances in High Energy Physics, Volume 2026, Issue 1, 2026.In this work, a renormalizable neutrino mass model based on (Z2 × Z4)⋊Z2 (II) symmetry is proposed for the modification of the μ − τ reflection symmetry. The hierarchies of lepton masses can be naturally realized, and the lepton mixing is addressed.

Semi-Contained Interactions of Atmospheric Neutrinos in the MACRO Detector [PDF]
, 2002 Atmospheric neutrinos arise from the decay of particles (primarily pions, muons and kaons) produced in the collision of high energy cosmic ray particles with the atmosphere.

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.Searches are being carried out at the Large Hadron Collider (LHC) for the decay of the CP‐odd scalar (A0) in two‐Higgs‐doublet models (2HDMs) with natural flavour conservation (NFC) in the channel A0⟶h0Z, where h0 is either the discovered 125 GeV Higgs boson or is an undiscovered CP‐even scalar with a mass below 125 GeV.

Viable secret neutrino interactions with ultralight dark matter
Physics Letters B, 2020 Several anomalies in neutrino oscillation experiments point to the existence of a ∼1 eV sterile neutrino νs mixing with νe at the level of Ue4≅0.1, but such a neutrino is strongly disfavored by constraints on additional light degrees of freedom (δNeff ...

Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model
Advances in High Energy Physics, Volume 2026, Issue 1, 2026.The transition magnetic moment for Majorana neutrinos is studied in a simple extension of the Standard Model. This extension incorporates two scalar Leptoquarks S1 and R~2 with quantum numbers 3¯,113,/ and (3, 2, 1/6), respectively. It is found that these Leptoquarks generate a sizable transition magnetic moment, particularly when the quark bottom is ...
