Is X(2370) a Glueball? What the Missing Decay Shows
BESIII’s missing K*(892) decay signal supports a flavour-singlet argument for X(2370). It does not uniquely label the state as a glueball. The limit’s scope, production models and an exploratory hybrid…

Watching Mass Form in Real Time: How Quantum Chips Are Simulating Particle Physics
Between early 2025 and mid-2026, quantum processors have gone from simulating toy models of particle physics to watching confinement, string breaking, and hadron scattering play out in real time. These…
