Three-loop QCD calculation hints at higher inclusive Vub value

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.

Preprint reports extra tetraquark resonances with a fuller basis

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.

Preprint links solar wind Alfvénicity to radiation belt swings

A preprint analyzing seven years of Van Allen Probes data reports that outer-belt electron flux was far higher during high-Alfvénicity solar wind, with seasonal coherence strongest near solar minimum. The observational result points to a possible role for magnetic fluctuations but does not establish causation or show that it applies beyond solar cycle 24.
