Paleo-Detectors as a Novel Probe of Dark Matter-Nucleus Effective Interactions

This paper reviews the theoretical sensitivity of paleo-detectors—mineral samples that record dark matter-induced nuclear recoils over geological timescales—to various WIMP-nucleus interactions within a Non-Relativistic Effective Field Theory framework, demonstrating that they can surpass or match the reach of conventional direct-detection experiments across a wide range of dark matter masses and interaction operators.

Enhancement of nonlinear pair production in a flying-focus pulse

This paper demonstrates that flying-focus laser pulses, which feature a focal point moving at the speed of light to extend interaction time, significantly enhance the yield of nonlinear Breit-Wheeler electron-positron pair production compared to conventional stationary-focus pulses, with improvements reaching up to 76% for high-energy gamma photons.

Atomic structure calculations for constraining new electron-electron forces

This paper presents a general atomic structure approach incorporating many-body corrections via the time-dependent Hartree-Fock method to constrain new electron-electron forces, establishing bounds on scalar-pseudoscalar and vector-axial vector couplings that rule out specific parameter regions and provide an updated Standard Model calculation for cesium parity non-conserving transitions.

Fermi gas of domain-wall Skyrmions in QCD in a strong magnetic field

This paper investigates the electromagnetic screening properties of fermionic domain-wall Skyrmions within the chiral soliton lattice of two-flavor QCD under a strong magnetic field, utilizing moduli effective theory and finite-temperature chiral perturbation theory to characterize baryon density saturation and predict static screening via a combined Debye mass.

From Thermal History to Multi-Messenger Signatures in Z3\mathbb{Z}_3 Symmetric Dark Sector

This paper investigates a Z3\mathbb{Z}_3-symmetric dark sector model featuring a right-handed neutrino, a dark fermion, and a complex scalar that collectively explain the observed dark matter relic density via annihilation, semi-annihilation, and conversion processes while simultaneously enabling a strong first-order electroweak phase transition with detectable multi-messenger signatures, including gravitational waves within the sensitivity range of future space-based detectors like LISA, BBO, and DECIGO.

Energy-dependent slow collective flavor conversion of supernova neutrinos

This study demonstrates that energy-dependent slow collective flavor conversion in supernova neutrinos, driven by spatially inhomogeneous instabilities, significantly enhances heating rates and increases the electron fraction by converting heavy-lepton neutrinos to electron neutrinos, thereby potentially driving supernova materials to be more proton-rich.

Simulations and flavour-scheme studies for Higgs-boson production in association with charm quarks

This paper presents a comprehensive NLO+PS study of Higgs-boson production with charm and bottom quarks, comparing massive and massless flavour schemes to quantify uncertainties and provide the first practical simulation recommendations for ccˉHc\bar{c}H production at the LHC.

Too good to go: Upcycling Phase-Space Points for Multijet Processes

This paper introduces a training strategy that leverages the nested structure of phase spaces to efficiently adapt high-dimensional samplers for multijet processes by augmenting existing NN-particle datasets to initialize (N+1)(N+1)-particle sampling, thereby significantly reducing computational costs while improving performance over current benchmarks.
