We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.

Systematic study of flow of protons and light clusters in intermediate-energy heavy-ion collisions with momentum-dependent potentials

This study utilizes the PHQMD approach with a novel momentum-dependent potential to demonstrate that a soft, momentum-dependent nuclear equation of state best reproduces experimental flow data for protons and light clusters in intermediate-energy heavy-ion collisions, while also revealing distinct flow signatures that can help discriminate between different cluster formation mechanisms.

New physics searches via angular distributions of $\bar{B} \to D^* (\to D \pi) \tau (\to \ell \nu_\tau \bar{\nu}_\ell) \bar{\nu}_\tau$ decays

This paper proposes a method to probe new physics in $\bar{B} \to D^* \tau \bar{\nu}_\tau$ decays by analyzing the angular distribution of the full cascade $\bar{B} \to D^* (\to D \pi) \tau (\to \ell \nu_\tau \bar{\nu}_\ell) \bar{\nu}_\tau$ , demonstrating through simulated data that this approach can constrain right-handed and tensor current couplings with approximately 5–6% precision while incorporating recent lattice QCD form factor correlations.

Update on non-unitary mixing in the recent NO $ν$ A and T2K data

This paper analyzes recent NO $\nu$ A and T2K data to test the non-unitary mixing hypothesis, providing updated best-fit parameters and tighter constraints on unitary violation while demonstrating that non-standard parameters can alleviate tensions between the experiments, alongside a projection of future sensitivities for NO $\nu$ A, T2K, and DUNE.

Effects of tau-neutrino detection on non-standard interactions at DUNE with a short discussion on the nature of neutrino mixing

This paper demonstrates that detecting tau neutrinos at the DUNE far detector significantly enhances sensitivity to Non-Standard Interactions, particularly the $\epsilon_{\mu\tau}$ parameter, while also improving constraints on mass hierarchy, CP violation, mixing octants, and the unitarity of the PMNS matrix.

Exploring the flavor structure of leptons via diffusion models

This paper proposes using diffusion models with transfer learning to generate neutrino mass matrices consistent with experimental data, revealing non-trivial distributions for CP phases and neutrino mass sums that offer new avenues for verifying lepton flavor models through future experiments.

WIMP/FIMP dark matter and primordial black holes with memory burden effect

This paper proposes a unified dark matter scenario where the total relic abundance arises from the sum of thermally produced WIMPs, PBHs stabilized by the memory burden effect, and non-thermal WIMPs or FIMPs emitted from those PBHs, provided specific conditions prevent the emitted particles from thermalizing and ensure PBHs do not dominate the universe's energy density.

Probing nuclear structure with the Balitsky-Kovchegov equation in full impact-parameter dependence

This paper extends the solution of the Balitsky-Kovchegov equation with full impact-parameter dependence to nuclear targets, providing predictions for key processes like deep-inelastic scattering and diffractive vector meson production to investigate gluon saturation and nuclear structure effects relevant for future facilities like the EIC and current LHC studies.

Exact, non-singular black holes from a phantom DBI Field as primordial dark matter

This paper presents the first exact, non-singular black hole solution in General Relativity sourced by the phantom branch of a Dirac-Born-Infeld scalar field, which resolves the central singularity via kinetic stiffness and allows primordial black holes to survive evaporation as gram-scale relics, thereby opening a new mass window for dark matter.

Quantum Corrections to Randall-Sundrum Model from JT Gravity

This paper investigates quantum corrections to the Randall-Sundrum model in a near-extremal black brane background by incorporating Jackiw-Teitelboim gravity and Schwarzian modes, deriving the corrected Kaluza-Klein mass spectrum, and analyzing the impact on the Goldberger-Wise mechanism to provide new insights into cosmology and phase transitions.
