The Masses of Fermions in the context of the Supersymmetric SU(3)C×SU(3)L×U(1)NSU(3)_{C}\times SU(3)_{L}\times U(1)_{N} Model

This paper presents a detailed analysis of the fermion mass spectrum in the Minimal Supersymmetric SU(3)C×SU(3)L×U(1)NSU(3)_{C}\times SU(3)_{L}\times U(1)_{N} model under both RR-parity conserving and violating scenarios, demonstrating that numerical predictions for all masses and mixing angles align with current experimental data.

Reanalyzing DESI DR1: 4. Percent-Level Cosmological Constraints from Combined Probes and Robust Evidence for the Normal Neutrino Mass Hierarchy

This paper presents a comprehensive reanalysis of DESI DR1 data combined with other cosmological probes, achieving percent-level constraints on key parameters and providing robust evidence favoring the normal neutrino mass hierarchy while setting the tightest bounds to date on the sum of neutrino masses and dynamical dark energy.

Tensor states ΥBc∗−ΥB_{c}^{\ast -} and J/ψBc∗+J/ψB_{c}^{\ast +}

Using QCD sum rules, this paper investigates the masses and decay properties of the tensor hadronic molecules MTb\mathcal{M}_{\mathrm{T}}^{\mathrm{b}} (ΥBc∗−\Upsilon B_{c}^{\ast -}) and MTc\mathcal{M}_{\mathrm{T}}^{\mathrm{c}} (J/ψBc∗+J/\psi B_{c}^{\ast +}), determining their instability against dissociation and calculating their full widths through dominant and subleading decay channels.

Imperfect axions with no domain wall problem

This paper demonstrates that post-inflationary axion theories with a domain wall number greater than one can be phenomenologically viable if additional PQ-violating operators destroy axion strings before the QCD potential becomes relevant, thereby resolving the domain wall problem while predicting a QCD axion mass in the 10−310^{-3}–10−210^{-2} eV range and a neutron electric dipole moment within reach of upcoming experiments.

Discovering Substellar Dark Matter Halos with Astrometric Weak Lensing of Multiply Imaged Quasars

This paper proposes using time-domain astrometric weak lensing of multiply imaged quasars to detect substellar dark matter halos by measuring their induced angular acceleration, a method capable of probing dark matter structures 12 to 14 orders of magnitude smaller than previously detected and significantly constraining dark matter particle properties.

Tidal effects on radiation in gravitational shockwave collisions

This paper computes high-frequency gravitational wave radiation from collisions between light and heavy compact objects using shockwave propagators, revealing a perturbative expansion of tidal response functions that connect Lipatov vertex amplitudes to Weinberg's soft radiation limits while highlighting double-copy structures with Yang-Mills gluon radiation.

Vector-boson-fusion timing references for four-dimensional displaced-vertex searches

This paper demonstrates that incorporating precision timing information from a future HL-LHC detector layer into vector-boson-fusion Higgs decay searches significantly enhances sensitivity to long-lived particles by converting displaced vertices into four-dimensional objects, thereby suppressing prompt heavy-flavor backgrounds and extending reach into regimes where traditional spatial-only searches lose acceptance.

Comparing Classical and Quantum Machine Learning for Regression in High Energy Physics Collision Data

This study systematically compares classical and quantum machine learning architectures for regression on simulated high-energy physics collision data, finding that while classical models like CNNs and LSTMs currently offer marginally better performance, quantum counterparts achieve competitive accuracy with significantly fewer trainable parameters, highlighting a distinct parameter-efficiency advantage for near-term quantum devices.
