Two-exponential decay of Acridine Orange
Francesco Giacosa, Anna Kolbus, Krzysztof Kyziol +4
In this work, we experimentally study the fluorescence decay of Acridine Orange at late times, in order to test whether a late-time power-law behaviour emerges, a feature expected…

Quantum Late-Time Decay and Channel Dependence
Francesco Giacosa, Anna Kolbus, Krzysztof Kyziol +4
Quantum mechanics predicts deviations from exponential decay at short and long times, yet experimental evidence is limited. We report a power-law tail after 10 lifetimes in t…

The rho-pi puzzle and vector glueball mixing
Arthur Vereijken
The is identified as the radial excitation of the . Based on perturbative QCD, the branching ratio of the into some final hadron state should be approximat…
