Continuum contribution to charged-current absorption of low-energy νe\nu_e on 40^{40}Ar

This paper presents refined calculations of low-energy νe\nu_e absorption on 40^{40}Ar using a hybrid HF-CRPA and statistical de-excitation model, revealing that the standard MARLEY model overestimates DUNE event yields by approximately 20% while potentially improving the feasibility of supernova pointing due to a more pronounced overestimation at backward angles.

Nanohertz gravitational waves from the baryon-dark matter coincidence

This paper proposes that the nanohertz gravitational waves detected by pulsar timing arrays originate from a cosmological phase transition at the 100 MeV scale, a specific energy level naturally predicted by a baryogenesis model involving resonant neutron-dark matter oscillations, which also offers testable predictions for dark matter self-interactions, neutron star masses, and particle physics experiments.

Thermodynamics of magnetized BPS baryonic layers and the effects of the Isospin chemical potential

This paper utilizes the Hamilton-Jacobi equation and Casimir effect techniques to derive analytical expressions for the thermodynamics of magnetized BPS baryonic layers within a gauged non-linear sigma model, establishing a unique connection between the grand canonical partition function and the Riemann zeta function while explicitly incorporating the effects of non-zero Isospin chemical potential.

Investigation of the l−l+νν‾l^{-}l^{+}\nu \overline{\nu} final state at multi-TeV muon colliders through the exclusive decay of ZZ/WW gauge bosons in the Randall-Sundrum model

This paper investigates the l−l+νν‾l^{-}l^{+}\nu \overline{\nu} final state at multi-TeV muon colliders within the Randall-Sundrum model, demonstrating that the production cross-sections are strongly influenced by unparticle parameters, muon polarization, and anomalous couplings, with WW boson decays yielding significantly larger rates than ZZ decays and showing enhanced sensitivity to new physics effects.

Emergence of dynamical tensor fields in composite models of gravity

This work demonstrates that in composite gravity models in the infrared regime, dynamical tensor fields with finite kinetic terms emerge via the functional renormalization group flow, reproducing the transverse-traceless sector of the diffeomorphism-invariant Einstein-Hilbert action, while longitudinal and trace contributions remain uninterpreted as gauge-fixing artifacts.
