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…
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…
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 approxi…
Scalar field with a time-independent classical source, not trivial after all: from vacuum decay to scattering
Leonardo Tinti, Arthur Vereijken, Shahriyar Jafarzade +1
Historically it has been believed that a time-independent classical source has no effect on the scattering of relativistic uncharged field, in contrast with single particle quantum…
