Glueballs and fractional anomalous determinants at nonzero , and the decays of the X(2370)
Francesco Giacosa, Shahriyar Jafarzade, Győző Kovács +3
Using fractional anomalous determinants, we construct a model of the trace and axial anomalies of a gauge theory at nonzero angle through the couplings to scalar and ps…
Chiral anomaly: from vacuum to Columbia plot
Francesco Giacosa, Győző Kovács, Péter Kovács +2
We use a low-energy effective approach, the extended linear sigma model, to study realizations of the anomaly with different operators, linear and quadratic in the 't Hoof…
Emergence of the polydeterminant in QCD
Francesco Giacosa, Michał Zakrzewski, Shahriyar Jafarzade +1
A generalization of the determinant appears in particle physics in effective Lagrangian interaction terms that model the chiral anomaly in Quantum Chromodynamics (PRD 97 (2018) 9,…
Anomalous couplings and the Columbia plot
Francesco Giacosa, Győző Kovács, Péter Kovács +2
When the quark masses are lighter than those in QCD, the standard lore is that a chiral transition of first order must emerge for three, light flavors. Recently, however, numerical…
Ordinary and exotic mesons in the extended Linear Sigma Model
Francesco Giacosa, Péter Kovács, Shahriyar Jafarzade
The extended Linear Sigma Model (eLSM) is a hadronic model based on the global symmetries of QCD and the corresponding explicit, anomalous, and spontaneous breaking patterns. In it…
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…
Could the OPERA setup send a bit of information faster than light?
F. Giacosa, P. Kovacs, S. Lottini
We argue that with the current experimental setup of the OPERA neutrino experiment no `bit' of information faster than light was or could be sent, and therefore no violation of Lor…
