Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper extends the phenomenological analysis of a flavor-dependent gauge extension of the Standard Model by relaxing the assumption of a strong scalar hierarchy, thereby revealing a new two-component dark matter scenario comprising both fermionic and scalar particles alongside the previously studied purely fermionic case, and identifying viable parameter spaces consistent with relic density and direct detection constraints.
This paper investigates the puzzling observation that dielectron emission temperatures in the intermediate mass region remain constant at approximately 287 MeV across a wide range of collision energies at RHIC and LHC, despite the expectation that initial parton plasma temperatures should rise significantly with increasing bombarding energy.
Using a Monte Carlo event generator with -factorization, the study demonstrates that the observed stronger-than-linear growth of D-meson yields in high-multiplicity pp and pPb collisions is reproduced by various initial-state spatial distributions, indicating that this observable is insufficient for distinguishing the specific matter geometry within the proton.
This paper extends the Left-Right Symmetric model with a sterile neutrino dark matter candidate and modular symmetry to investigate how varying modular weights influence the relic abundance of dark matter and the mechanism of leptogenesis.
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.
