Model predicts a switch in particle production in proton-oxygen collisions
A preprint model comparison with eight centrality classes and preliminary ALICE data suggests the peak could move from the oxygen-going side to the proton-going side.
Preprint develops a new way to handle quarks and gluons near x = 1
A theoretical QCD study factorizes and resums next-to-leading-power terms in deep-inelastic scattering, while leaving non-perturbative inputs and higher-logarithmic work open.
Free spin waves match 2D Heisenberg magnet's leading thermodynamics
Preprint: A fixed-spin theorem for a square-lattice Heisenberg ferromagnet finds the free-boson coefficient for its leading low-temperature free energy.
Preprint Finds Higher Workplace Well-Being Scores Associated With App Use
A three-month workplace field study reported a modest rise in self-reported PERMA scores, but its nonrandomized design leaves the result as an exploratory association.
Preprint reports high-fidelity gates and five-qubit entanglement
The reported processor reached 99.957(5)% median single-qubit fidelity and 90.0(2)% five-qubit GHZ fidelity, while readout ranged from a 94% median to 85.5% at its lowest.
Degree rules split the difficulty of finding spanning trees
Preprint: A mathematical analysis reports tractable and W[1]-hard cases across several graph-structure measures.
Higgs-Pair Rates Could Exceed the Standard Model in New Scan
Preprint: A U(1)_X model predicts 60 to 100 fb at the 14 TeV LHC, above the paper’s 35 to 40 fb Standard Model benchmark.
Models estimate hundreds of supermassive black-hole pair candidates
Preprint: A population model estimates hundreds of candidate systems, while joint spectral and periodic tests select far fewer.
Study predicts tiny rates for rare top-quark meson decays
Preprint calculates tiny Standard-Model rates and an almost absent right-handed vector signal.
Welding cable model changes how robot joint loads are calculated
Preprint: A planar simulation found that a modeled welding umbilical can noticeably alter a robot’s dynamic response despite its much lower mass.
ClueWeaver Leads Local Methods on Four Evaluated Narrative Benchmarks
A preprint reports that ClueWeaver recorded 59.0% overall accuracy across four long-context narrative benchmarks, with paragraph-level evidence traces.
Near-Field Beamforming Nearly Matches Full SVD at Lower Cost
This arXiv preprint reports near-full-SVD rates and much lower CPU time for a geometry-based dual-UPA design.
FedRep records 1.34 bps/Hz in a simulated three-cell comparison
This preprint reports simulated results for a system that jointly optimizes beamforming and fluid-antenna port selection across multiple cells.
New Software Model Targets Reversible Hot-Swapping of Components
Preprint sets out formal rules for reversing component effects and managing changing dependencies, with a qualitative Koishi case study.
LY UMa Appears Bluer When It Is Brighter, Preprint Says
Preprint: Optical measurements estimate a K7-K8V donor, but leave LY UMa's classification unresolved.
Simulated quantum reservoirs show a scaling edge as information scrambles
Preprint simulations found the strongest short-term forecasting and superextensive memory scaling near the onset of information scrambling.
OpenVeinNet reports lower error in held-out finger-vein tests
Preprint: An arXiv version 1 study reports the lowest error in four of five full-subject splits, while few genuine comparisons limited resolution at the strictest VERA threshold.
New framework gives sparse bounds in abstract Orlicz-Morrey spaces
Preprint: Theoretical results cover weighted bounds, commutators and duality, but depend on structural assumptions.
Game-building traces linked to stronger world-model test results
Preprint: A proposed system blends human acceptance feedback with game-engine checks and reports leading Unity scores plus positive transfer and embodied diagnostic results.
