This paper demonstrates that even with optimized inputs and precise dispersive data, the two-channel rescattering mechanism remains insufficient to explain the large CP violation observed in charm-meson decays within the Standard Model, while also providing new constraints on CP asymmetries through sum rules.
This paper demonstrates that by optimizing the exponentiated-Hamiltonian decomposition for product-formula algorithms, the T-gate cost of simulating quantum chromodynamics in the electric basis can be reduced by a factor of nearly , effectively removing an exponential-in- overhead previously attributed to the method.
This paper proposes that ultra-high-energy neutrinos scattering off nucleons in dense astrophysical environments can generate TeV photons via pion decay, offering a quantitative explanation for the preburst TeV emission observed in GRB 221009A and establishing a new link between neutrino and gamma-ray observations in multi-messenger astronomy.
This paper demonstrates through N-body simulations that significant small-scale isocurvature perturbations in a subdominant ultralight dark matter component can lead to its stochastic dominance in the centers of small halos, offering a potential explanation for the observed diversity of galaxy cores.
This paper investigates how quantum memory burden effects, Bardeen regularization, and Kerr rotation influence the neutrino emission from primordial black holes, deriving constraints on their dark matter abundance using current and future high-energy neutrino observatories while highlighting the distinct impacts of spin and regularization on detection sensitivity.
This paper revisits scalaron dark matter in gravity by resolving previous ambiguities in its one-loop decay rate into photons, demonstrating that the resulting cosmological radiation is consistent with observations while confirming that primordial scalaron production is negligible, thereby supporting the scenario where scalarons constitute all dark matter as a coherently oscillating field.
This paper investigates the mass spectra and strong decays of the family using the modified Godfrey-Isgur quark model and the quark-pair creation model, suggesting that the recently observed resonance is a promising candidate for the state while also predicting the properties of the and states.
This paper demonstrates that extending partial-wave analysis to include circular and elliptical photon polarization resolves remaining mathematical ambiguities in two spinless meson photoproduction and enables the reaction dynamics themselves to serve as a polarimeter, a technique validated using GlueX experiment data.
This paper proposes a "Radiative Inflation and Dark Energy" (RIDE) model based on a complex scalar field with radiative corrections and non-minimal gravity coupling, which successfully reconciles chaotic inflation predictions with recent ACT and Planck observational data by adjusting the tensor-to-scalar ratio and spectral index.
This paper proposes an improved method for calculating entanglement entropy in Deep Inelastic Scattering using Kharzeev-Levin's approach on structure functions, demonstrating strong agreement with H1 and HERA data across a wide kinematic range while investigating the transverse photon polarization effect and higher twist contributions at low and .
