This paper combines non-linear shock wave theory with frame-by-frame video analysis of the 2020 Beirut explosion to derive the Landau-Whitham formula for overpressure layer thickness and demonstrate strong agreement between theoretical predictions and observational data.
The paper introduces NuFast-Earth, a fast, flexible, and accurate C++ algorithm designed to efficiently compute neutrino oscillation probabilities for atmospheric, nighttime solar, and supernova neutrinos traversing the Earth's varying density profiles, thereby addressing the growing computational demands of next-generation neutrino experiments.
This study analyzes the covariance spectrum of the black hole X-ray binary MAXI J1820+070 up to 150 keV, revealing a high-energy coherence drop and distinct electron temperature behaviors that support a two-Comptonization model where short-timescale variability originates from an elevated inner region illuminated by cooler disk photons, while long-timescale variability arises from larger radii.
This paper computes all planar three-loop master integrals required for leading-colour N3LO QCD corrections to the production of two massive or off-shell vector bosons at hadron colliders by constructing pure integral bases, deriving canonical differential equations via finite field techniques, and solving them using generalised power series expansions.
This paper presents the first complete next-to-leading-order calculation of BFKL impact factors for the hadroproduction of specific NRQCD quarkonium states by combining virtual corrections with real-emission contributions, demonstrating the cancellation of soft divergences and the compatibility of surviving collinear singularities with factorization to enable future next-to-leading-logarithmic precision studies.
This paper employs Light-Front Hamiltonian Effective Field Theory with non-perturbative multi-pion contributions to demonstrate that higher-order Fock components are crucial for accurately describing nucleon flavor asymmetry and to establish a unified framework for investigating similar nuclear effects in light nuclei like the deuteron.
Using an effective Lagrangian approach calibrated to existing data, this study successfully reproduces the production cross sections of high-spin and mesons in reactions and predicts measurable, forward-peaked production rates for their partners, suggesting their feasibility for observation in future meson-beam experiments.
This paper presents the public release of OpenGadget3, a cosmological hydrodynamical N-body code featuring a robust implementation of self-interacting dark matter that supports various elastic scattering cross-sections and two-species models, validated through accuracy tests and performance scaling.
This paper investigates the production of global vortex-antivortex pairs in 2+1 dimensions through numerical scattering experiments where a complex scalar field and a real scalar scatterer interact solely via a quantum mediator, revealing that vortex creation is highly sensitive to initial conditions and exhibits a chaotic parameter space with isolated production regions.
Using the functional renormalization group within the quark-meson model, this study demonstrates that the critical scaling region of the chiral phase transition systematically shrinks as chemical potential increases, with consistent results observed across both local potential approximations.
