This paper demonstrates that evaporating black hole populations with finite-width mass distributions universally exhibit a characteristic power-law suppression in their induced gravitational wave backgrounds at late times, a phenomenon driven by evaporation dynamics rather than initial mass distribution details.
While fuzzy dark matter provides an excellent fit to the rotation curves of nearby dwarf irregular galaxies with an axion mass of approximately eV, the model is ultimately ruled out by significant tensions () regarding the observed core scaling relations and the suppression of the linear power spectrum.
This paper investigates the impact of nonperturbative effects on triple-differential dijet and Z+jet production using Monte Carlo event generators, revealing significant process-dependent differences that motivate a proposed triple-differential measurement of the underlying event in Z+jet production to resolve whether this non-universal behavior exists in nature.
This paper systematically constrains the parameter space of a simplified dark matter model featuring a light spin-0 mediator (mass < 10 GeV) by integrating flavor physics, electroweak precision data, fixed-target experiments, and cosmological bounds, while specifically assessing its potential to explain recent Belle-II results on invisible B-meson decays.
This paper presents a multi-methodological study combining Density Functional Theory with nuclear quantum mechanics to analyze how graphene substrates influence the -decay spectrum of tritium, offering critical insights for optimizing hosting materials in future neutrino experiments.
This paper introduces the Minimum Clique-optimised quantum Algorithm (MCA), a graph theory-based automated quantum method that efficiently queries causal configurations in multiloop Feynman diagrams by mapping propagators to qubits and optimizing circuit depth and area through the Minimum Clique Partition problem.
This paper presents "Niñas Atómicas," a Chilean workshop initiative that empowers high school girls to develop critical thinking and scientific skills by building muon detectors under the mentorship of female scientists, while sharing the program's methodology, experimental results, and participant experiences to advance physics education and outreach.
This paper presents the first study of jet substructure modifications during the bottom-up evolution of out-of-equilibrium QCD matter, demonstrating that the early stages of bulk matter evolution in heavy-ion collisions leave a sizable imprint on jet radiation patterns and establishing a foundation for incorporating pre-equilibrium dynamics into realistic jet quenching models.
This paper utilizes QCD light-cone sum rules to calculate the magnetic dipole, electric quadrupole, and magnetic octupole moments of , , and molecular pentaquarks, establishing a hierarchy of magnetic moments and spatial deformation signatures that serve as critical benchmarks for distinguishing their molecular structure from compact exotic hadron models.
This paper develops a Fermi-liquid framework to derive leading-order expressions for shear and bulk viscosities in cold, dense nucleon matter, demonstrating that the bulk-to-shear viscosity ratio scales as in the degenerate regime and remains robust against quasiparticle mass corrections when coupled with a Walecka-type equation of state.
