Electroweak and Single Top-Quark Conspiracy in Current LHC Data

This paper analyzes recent LHC rate shifts in electroweak single top-quark and top-associated Higgs production using Standard Model Effective Field Theory to identify a specific pattern of dipole and gauge deformations, concluding that while no single weakly coupled particle multiplet can explain the data, a minimal multi-threshold vector-like-quark sector offers a viable, albeit complex, ultraviolet origin consistent with current experimental constraints.

Disentangling Charged-Current Scalar NSI from the Solar Sector at JUNO

This paper presents the first reactor-based determination of individual charged-current scalar non-standard interaction parameters using JUNO data, demonstrating that spectral distortions in electron antineutrino survival probability allow for the breaking of degeneracies with the solar mixing angle at a $3\sigma$ confidence level.

What Neural Network Field Theory Can and Cannot Realise on a Computer

This paper presents a no-go theorem demonstrating that standard finite-width neural network ensembles cannot consistently realize either quantum or effective field theories on a computer due to failures in reflection positivity and scale separation, with only specific infinite-width limits or relaxations of finite variance and rotation invariance offering potential escapes.

Textures of dimension-six operators in the SMEFT with non-invertible selection rules

This paper classifies the flavor textures of baryon-number-conserving dimension-six SMEFT operators under non-invertible selection rules, revealing distinct Wilson coefficient structures and flavor patterns that deviate from Minimal Flavor Violation and offer unique predictions for B-meson and charged-lepton-flavor-violating observables.

Integrating Heisenberg uncertainty and maximum entropy principles verses statistical approach to nucleon structure

This paper determines nucleon parton distribution parameters using two distinct approaches—one combining Heisenberg uncertainty and maximum entropy principles with sum rules, and another employing a statistical thermodynamic model—and demonstrates that both methods yield valence quark and gluon densities consistent with existing parametrizations for calculating structure functions.

Searching for signatures of self-interacting dark matter in halos from full-physics simulations: From 3D structure to projected observables

This study utilizes full-physics simulations to demonstrate that while baryonic and projection effects generally suppress self-interacting dark matter (SIDM) signatures in galaxy groups, weak lensing and kinematic analyses of massive clusters offer promising avenues for detecting SIDM imprints, potentially revealing up to 20% deviations in shear profiles for halos exceeding $10^{13}\ \text{M}_\odot$ .

Theoretical description of the $D^{+} \to \bar{K}^{0} \pi^{+} \pi^{0} \pi^{0}$ reaction

This paper presents a theoretical study of the $D^{+} \rightarrow \bar{K}^{0} \pi^{+} \pi^{0} \pi^{0}$ decay, combining quark-level emission mechanisms with direct resonance production to successfully reproduce experimental mass distributions for the $\bar{K}^{*0}$ and $\rho^{+}$ structures using six fitted parameters.

Down-Type Jet Identification in Fully Hadronic $t\bar t$ Events

This paper presents a novel two-stage machine-learning framework combining GNNs, Transformers, and conditional diffusion models to successfully identify down-type jets in fully hadronic $t\bar{t}$ events, thereby enabling effective spin-correlation and entanglement studies in a channel previously hindered by QCD background and reconstruction challenges.

Effects of RG running in breaking $\mu-\tau$ reflection symmetry, conventional versus minimal seesaw

This paper investigates the radiative breaking of $\mu$ - $\tau$ reflection symmetry via renormalization group evolution within the minimal seesaw framework, performing a systematic numerical analysis to determine if the model's constrained high-energy parameters can reproduce current low-energy neutrino oscillation data and comparing these results with the conventional Type-I seesaw scenario.

Particle Dark Matter in the 1980s and 1990s

This paper reviews the transformative period from the 1980s to the 2000s during which the concept of particle dark matter became a central pillar linking particle physics and cosmology, evolving the field from a state of uncertainty to the establishment of the precise $\Lambda$ CDM standard model.
