Abstract

We study neutrino masses in the framework of the supersymmetric inverse seesaw model. Different from the non-supersymmetric version a minimal realization with just one pair of singlets is sufficient to explain all neutrino data. We compute the neutrino mass matrix up to 1-loop order and show how neutrino data can be described in terms of the model parameters. We then calculate rates for lepton flavour violating (LFV) processes, such as $μ\to e γ$, and chargino decays to singlet scalar neutrinos. The latter decays are potentially observable at the LHC and show a characteristic decay pattern dictated by the same parameters which generate the observed large neutrino angles.

Probing Proton Structure via Physics-Guided Neural Networks in Holographic QCD

Describing the proton structure function $F_2(x,Q^2)$ across the nonperturbative and transition regimes of QCD remains a major theoretical challenge. We construct a physics-guided phenomenological representation combining fermion-resonance and Pomeron-like AdS/QCD basis functions with a neural parametrization. The resonance sector is constrained by the AdS eigenvalue problem and physical proton mass, while the neural component describes effective kinematic mixing, Pomeron normalization, and a regularized log-space correction. For 187 selected SLAC measurements, a fixed 153/34 training--test split gives $χ^2/N_{\rm train}=0.542$, $χ^2/N_{\rm test}=1.990$, and $χ^2/N_{\rm all}=0.805$. Conditional on the chosen holographic basis, the fitted channel fractions evolve continuously from Pomeron-like dominance at lower measured $x$ to fermion-resonance dominance at larger $x$. The mixing midpoint is at $x\simeq0.187$, while equality of the final channel fractions occurs at $x\simeq0.226$, defining a transition region $x\simeq0.19$--$0.23$ rather than a unique boundary. Although $α_0\simeq1.08$ is compatible with the data, fixed-$α_0$ refits show that it is not separately identifiable from the flexible Pomeron normalization. The $x$-dependent holographic coordinates and effective excited scales should therefore be regarded as basis-dependent quantities rather than direct measurements of an $x$-dependent proton spectrum. A data-only neural baseline shows no predictive advantage for the holographic basis on the present dataset. The framework thus provides a basis-conditioned phenomenological decomposition rather than a model-independent extraction of proton dynamics.

Vertexing displaced diphoton decays with recoil photons at Belle II

We propose a recoil-assisted strategy for vertexing displaced diphoton decays in $e^+e^-\toγX$, $X\toγγ$, using only one converted daughter photon. The initial state and recoil-photon momentum define the LLP flight line, whose closest approach to the converted-photon trajectory locates the decay vertex. This removes the need for a second conversion, making the conversion-related efficiency scale linearly rather than quadratically with the photon-conversion probability. For photophilic axionlike particles at Belle II, the existing $408$ fb$^{-1}$ data set could probe previously unconstrained parameter space near $m_a \simeq 100$ MeV and $g_{aγγ} \simeq 2 \times 10^{-4}$ GeV$^{-1}$, improving leading bounds by almost an order of magnitude and testing the mass region below the $π^0$ mass, which the existing Belle II three-photon searches cannot access. With $50$ ab$^{-1}$, the reach extends to $m_a \simeq 310$ MeV and $g_{aγγ}\simeq2\times10^{-5}$ GeV$^{-1}$.

Three-Body Holonomy as a Toy-Model Mechanism for Family Triplication and Mass Hierarchy in (1+1) Dimensions

We investigate the phenomenological consequences of a genuine three-body holonomy in a relativistic Dirac system in one spatial dimension. After removing the center-of-mass coordinate, the triple-coincidence point punctures the two-dimensional relative configuration space and permits a nontrivial $U(1)$ winding phase, whereas the pairwise Sakamoto--Munakata--Ino contact interactions give trivial net matching around this point. At fixed intrinsic parity, the six particle-ordering sectors reduce to a three-dimensional cyclic space. A Hermitian $C_3$-invariant effective mass operator admits a Peierls-type realization in which the gauge-invariant phase around the three links equals the three-body holonomy $θ_3$. Its eigenvalues are $$ M^{[k]}=M_0+2Δ\cos\!\left(\frac{θ_3+2πk}{3}\right), \qquad k=0,1,2. $$ The holonomy lifts the conjugate-channel degeneracy and can generate a parametrically light branch through cancellation between the common mass and the holonomy-induced shift. We further allow cyclic-symmetry breaking and consider a general Hermitian three-state mass matrix. Exact elimination of two heavy states by the Schur complement yields a low-energy correction containing the rephasing-invariant loop product $\mathrm{Re}(t_{12}t_{23}t_{31})\propto\cosθ_3$. Thus, even when only one branch is kinematically accessible, its effective mass can retain finite memory of the complete three-state loop. The complementary invariant $\mathrm{Im}(t_{12}t_{23}t_{31})\propto\sinθ_3$ is phase sensitive but does not alone imply CP violation. The construction provides a low-dimensional phenomenological proof of concept for family-like triplication, mass hierarchy, and infrared memory, rather than a microscopic theory of Standard Model fermion generations.
