A new theoretical study reports three-loop heavy-to-light QCD form factors and uses them to supply higher-order inputs for inclusive B-decay calculations. Its preliminary semileptonic result points to a lower partial rate and a possible rise in the inclusive Vub value, while the perturbative tail and full uncertainty analysis remain unfinished.

A preprint study reports that a fuller set of Jacobi coordinates changed the predicted tetraquark spectrum, revealing additional resonance poles in strange-charm and double-charm calculations. It also reports bound states in heavier systems and fully charmed poles associated with X(6900) and X(7200), subject to model-specific uncertainty.

A formal analysis finds exactly two symmetry-preserving directions for splitting a gravity connection into shape and scale, while the resulting choices form a smooth one-dimensional family. It recovers Palatini dynamics in the exact sector but does not establish that the broader construction describes a physical theory.

A mathematical analysis links equal-weight magic-witness thresholds in codeword-stabilized quantum codes to the affine geometry of their classical word sets. It gives exact lower bounds for selected examples and a family-level formula, but leaves the larger Rains family without a scalable algorithm.

An arXiv preprint presents NuGlass, an open-source web application that turns three-flavor neutrino-oscillation calculations in constant-density matter into six linked 3D views.

A modeling study reports that charm-hadron ratios differ between jet-contained and inclusive events, while baryon and meson ratios respond differently to relative transverse activity.
