On the failure of the rule in and decays
Arthur Vereijken, Francesco Giacosa
The rule relates hadronic decays of the and through the ratio of their wave functions at the origin, but is strongly violated in several vector--pseudoscalar (…
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…
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…
Tensor glueball decay into nucleon-antinucleon
Arthur Vereijken
In the context of a chiral hadronic model, we compute the decay ratio of a tensor glueball decaying into a nucleon and antinucleon compared to the decay into 2 pions. Tensor meson…
Decays of the tensor glueball in a chiral approach
Arthur Vereijken
Glueballs remain an experimentally undiscovered prediction of QCD. Lattice QCD predicts a spectrum of glueballs, with the tensor glueball being the second lightes…
Is the tensor glueball?
Arthur Vereijken, Shahriyar Jafarzade, Milena Piotrowska +1
Glueballs remain an experimentally undiscovered expectation of QCD. Lattice QCD (As well as other theoretical approaches) predicts a spectrum of glueballs, with the tensor ($J^{PC}…
From well-known tensor mesons to yet unknown axial-tensor mesons
Shahriyar Jafarzade, Arthur Vereijken, Milena Piotrowska +1
While the ground-state tensor () mesons , , , and are well known experimentally and form an almo…
