Multi-band cross-correlation dark sirens: Enhancing cosmological parameter and gravitational-wave bias constraints

This paper presents the first Fisher forecast demonstrating that multi-band gravitational-wave observations, combining space-based B-DECIGO and ground-based Einstein Telescope and Cosmic Explorer detectors, significantly enhance cosmological parameter constraints and enable unprecedented redshift-resolved measurements of gravitational-wave clustering bias compared to single-band or ground-only configurations.

Dressed Fock Spaces in Gauge Theory and Gravity

This paper resolves the issue of non-factorising multi-particle states in infrared-finite gauge and gravitational theories by introducing new zero modes and utilizing asymptotic symmetry Goldstone modes, thereby restoring the standard Fock-space factorisation for dressed particles.

The O(4)-breaking bubble

This paper explicitly constructs a nonradial, O(4)-breaking false vacuum decay solution for a scalar field theory with a specific sextic potential, revealing a configuration of two orthogonal bubble-tubes that supports real-time evolution and possesses an odd number of unstable modes.

LIGO, LISA and Ultralight Axion-like Dark Matter

This paper proposes that gravitational wave interferometers like LIGO and LISA can detect ultralight axion-like dark matter by measuring periodic polarization or phase modulations in their laser beams, with LISA projected to achieve sensitivities orders of magnitude better than current helioscope bounds for masses between $10^{-19}$ and $10^{-16}$ eV.

Modular $S_4$ Scotogenic Model with Flavored Resonant Leptogenesis

This paper proposes a radiative neutrino mass model combining the scotogenic mechanism with modular $S_4$ flavor symmetry, which successfully explains neutrino oscillation data, predicts a specific dark matter candidate and neutrinoless double beta decay signature, and generates the observed baryon asymmetry via resonant leptogenesis without fine-tuning.

Search for Invisibly Decaying Light Scalars at the FCC-ee

This paper investigates the potential discovery of invisibly decaying light scalars at the FCC-ee operating at 240 GeV by analyzing their production in association with hadronically decaying Z bosons, demonstrating that the collider could achieve sensitivities of 0.01–1 fb and potentially discover new scalars with masses up to 80 GeV depending on the mixing angle.

Ultraviolet Structure of Real-time Gravitational Wave Linear Response in a Resonant Scalar Field

This paper utilizes the Schwinger-Keldysh formalism and adiabatic regularization to analyze the ultraviolet structure of real-time gravitational wave linear response in a resonant scalar field, identifying specific time-dependent divergences that require new local counterterms and revealing a renormalization mismatch with the tadpole stress tensor that is attributed to the off-shell nature of the background.

Static linear response of hot and dense QCD matter to electromagnetic fields: Leading hard and soft QCD corrections

This paper computes the static electromagnetic susceptibilities of hot and dense quark-gluon plasma using perturbative QCD with leading hard and soft corrections, bridging the gap between perturbative calculations and Lattice QCD results to provide first-principle constraints on the plasma's electromagnetic response at finite baryon chemical potential where Lattice methods fail.

Chiral-odd structure of the $N \to \Delta$ transition: tensor form factors from QCD light-cone sum rules

This paper presents the first direct calculation of the four tensor transition form factors for the $N \to \Delta$ transition using QCD light-cone sum rules, revealing distinct flavor decomposition patterns and providing model-independent chiral-odd inputs for future phenomenological analyses.

Sommerfeld Enhancement in Spin-1 Electroweak Dark Matter

This paper investigates a renormalizable spin-1 electroweak dark matter model where Sommerfeld enhancement and annihilation into heavy vector bosons allow for thermal relic abundances at masses between 3.6 and 9.2 TeV, a range distinct from lower-mass spin-0 or spin-1/2 scenarios, with the entire viable parameter space being testable by the Cherenkov Telescope Array Observatory via a characteristic double-peak gamma-ray signature.
