This paper presents sensitivity projections for the NUCLEUS experiment at Chooz, demonstrating its potential to achieve a 4.7 observation of coherent elastic neutrino-nucleus scattering and provide leading constraints on new physics by utilizing gram-scale cryogenic calorimeters to access unprecedentedly low nuclear recoil energies.
This paper presents a unified framework that links microscopic Boltzmann equation treatments to phenomenological hydrodynamic models by deriving a power-law scaling for the friction parameter, thereby offering an efficient method to accurately estimate bubble wall velocities in first-order cosmological phase transitions.
This study analyzes the angular distribution of low-mass dimuon pairs in simulated 500 GeV electron-positron collisions at the ILC to distinguish Standard Model Drell-Yan processes from Beyond the Standard Model scenarios using the mono-Z' model, ultimately establishing 95% confidence level upper limits on the masses of the spin-1 Z' boson and associated fermionic dark matter in the absence of new physics discoveries.
This chapter introduces the fundamentals of the three-flavor neutrino oscillation paradigm, detailing the six undetermined oscillation parameters, the experimental history of the phenomenon, and the theoretical framework including matter effects that guide current large-scale particle physics experiments.
This paper demonstrates that the Cherenkov Telescope Array Observatory (CTAO) can achieve competitive sensitivity to annihilating and decaying dark matter signals by cross-correlating -ray emission with low-redshift galaxy catalogs like 2MASS using approximately 50 hours of integration time.
This paper proposes a novel method for detecting dark matter axions by monitoring the temperature rise in a quantum Hall sample placed within a resonant cavity, where the absorption of amplified axion-induced radiation causes a measurable thermal increase proportional to the axion's mass and coupling strength.
This paper presents the first exact analytical solution to the DeWitt-Brehme-Hobbs equation for a charged mass interacting with copropagating electromagnetic and gravitational plane waves, demonstrating how gravitational waves can qualitatively alter electromagnetic radiation-reaction effects.
This study utilizes revised accretion efficiency models and MESA binary evolution calculations to constrain the masses and spins of black holes in IC 10 X-1, NGC 300 X-1, and Cyg X-3, revealing that these Wolf-Rayet X-ray binaries are likely to evolve into binary black hole systems that will merge within a Hubble time and serve as detectable gravitational wave sources for the LVK network.
Using chiral perturbation theory, this study derives the one-pion exchange potential in strong magnetic fields, revealing that the potential's range decreases in all directions and induces a deuteron energy shift comparable to its binding energy at field strengths around the pion-mass scale.
This paper demonstrates that a massive dark companion orbiting the Galactic Center's supermassive black hole can dynamically excavate a "scoured" region within the dark matter spike, significantly suppressing indirect dark matter annihilation signals—particularly in shallower spike profiles—through gravitational heating and angular momentum exchange.
