NNLO QCD corrections to unpolarized and polarized electroweak structure functions in semi-inclusive deep-inelastic scattering

This paper presents next-to-next-to-leading order (NNLO) QCD corrections for both unpolarized and polarized semi-inclusive deep-inelastic scattering structure functions involving neutral and charged current interactions, demonstrating their significant phenomenological impact and reduced scale dependence for future Electron-Ion Collider analyses and global parton distribution function extractions.

Ultraheavy Atomic Dark Matter Freeze-Out through Rearrangement

This paper proposes that symmetric ultraheavy atomic dark matter (ranging from $10^6$ to $10^{10} \,\mathrm{GeV}$ ) can be thermally produced in the early Universe via a freeze-out mechanism dominated by the geometrically enhanced atomic rearrangement annihilation channel.

Detecting meV-Scale Dark Matter via Coherent Scattering with an Asymmetric Torsion Balance

This paper proposes a novel torsion balance experiment using test bodies of varying geometric sizes to detect meV-scale dark matter through its coherently enhanced scattering effects, thereby establishing the strongest constraints on dark matter-nucleon scattering cross-sections in the $(10^{-3}, 1)$ eV mass range.

The Signals of Doomsday I: False Higgs vacuum decay signatures

This paper proposes that small black holes could catalyze the decay of a false Higgs vacuum, creating expanding true vacuum bubbles whose friction-induced thermal production of Higgs particles generates detectable high-energy photon and neutrino bursts that could serve as early warning signals before the bubble wall reaches Earth.

Phase space fractons

This paper generalizes the construction of fracton models to phase space by classifying systems with multipole conservation laws and analyzing a new self-dual model that exhibits quasi-periodic orbits, thereby preventing full ergodic exploration of the phase space.

Magnetodynamic Characteristics and QGP Energy Dissipation in RMHD Framework with Relativistic Heavy-Ion Collisions

This study utilizes a (1+1)D relativistic magnetohydrodynamic framework with Bjorken flow to demonstrate how time-dependent ultra-strong magnetic fields and temperature-dependent magnetic susceptibility differentially influence Quark-Gluon Plasma energy density evolution, revealing that magnetic pressure suppresses decay in ultra-relativistic fluids while enhanced coupling accelerates dissipation in conformal fluids.

Up-type FCNC in presence of Dark Matter

This paper proposes a minimal extension of the Standard Model featuring a $\mathbb{Z}_3$ -stabilized complex scalar dark matter candidate coupled to up-type quarks via a heavy vector-like quark, successfully addressing up-type flavor-changing neutral currents and dark matter relic density while offering testable signatures at future muon colliders.

Neutrino Fluence influenced by Memory Burdened Primordial Black Holes

This paper demonstrates that quantum gravitational memory burden significantly suppresses neutrino signals from primordial black holes, rendering them undetectable by current IceCube observations even when considering beyond-Standard-Model heavy neutral leptons and realistic dark matter halo distributions.

Gravitational Wave Signals in a Promising Realization of SO(10) Unification

This paper investigates gravitational wave signals in a non-supersymmetric SO(10) grand unified model, demonstrating that the first step of symmetry breaking can induce a first-order phase transition producing a detectable background, though current experimental sensitivity remains insufficient for observation.
