This paper proposes using stationary Mössbauer spectroscopy with high energy resolution to probe ultralight scalar dark matter interactions with atomic nuclei, demonstrating that isotopes like can achieve competitive sensitivity to dark matter couplings in the mass range of to eV.
This paper presents a systematic analysis of relativistic Coulomb corrections in various neutral -meson decays involving lepton pairs, demonstrating that including these effects significantly improves the agreement between theoretical predictions and experimental data for channels like and , thereby establishing them as a crucial systematic consideration for high-precision -physics and New Physics searches.
This paper presents a general framework for predicting electron capture rates in using exact leptonic wave functions and a non-factorized treatment of the transition matrix element to quantify non-factorization effects and compare theoretical predictions for , , and ratios with current experimental data.
This paper employs an improved relativized quark model with rigorous mixing effects and a two-step GEM calculation scheme to systematically analyze low-lying positive-parity singly heavy baryon states, achieving high-precision mass predictions with a statistical error of only 6.96 MeV that validate the model's reliability and provide valuable references for future research.
Using TNG50 simulations of nearly one hundred Milky Way-like galaxies, this study reveals that dark matter halos ubiquitously exhibit corotation with the baryonic disk, a finding that significantly suppresses scattering rates for light dark matter and introduces a 21% uncertainty in direct detection cross-section limits that can be reduced to 7% by constraining the Milky Way's rotational velocity.
This paper proposes an composite model where Standard Model particles emerge as bound states, demonstrating that a specific flavor structure with two spurions can simultaneously reproduce all quark and lepton masses and the CKM matrix while predicting that electron electric dipole moments and neutral kaon mixing provide the most stringent constraints on the compositeness scale, potentially reaching up to TeV.
This paper provides an overview of hadron spectroscopy, highlighting how the discovery of exotic hadrons and advancements in experimental and computational techniques are expanding our understanding of Quantum Chromodynamics beyond the traditional quark model.
This paper utilizes a self-consistent light-front quark model to determine the - mixing angle as by fitting CLEO and BABAR transition form factor data, a result that aligns with LHCb measurements and successfully predicts various nonperturbative properties of the and mesons, including their decay constants and electromagnetic radii.
This paper presents a unified analysis demonstrating that matter-induced extrinsic CPT violation and Earth density stratification are correlated systematics in long-baseline neutrino experiments that must be jointly modeled to accurately reconstruct the CP phase and determine the mass ordering, particularly for long baselines where density profile approximations introduce significant biases.
This paper demonstrates that kinetic backreaction from ultralight axion condensates cannot suppress their quantum pressure to enhance structure growth, as the oscillation-averaged effect invariably strengthens the pressure and increases the Jeans length over time.
