Fine Structure and Decays of Hidden-Strangeness Tetraquarks in the Dynamical Diquark Model
Shahriyar Jafarzade, Richard F. Lebed
We analyze the fine structure and ``fall-apart'' decay patterns of hidden-strangeness tetraquarks within the dynamical diquark model. Several well-established negative-parity reson…
Diabatic Dynamical Diquark Model of Hidden-Strangeness Tetraquarks
Shahriyar Jafarzade, Richard F. Lebed
We generalize our recent analysis of hidden-strangeness tetraquarks within the dynamical diquark model from its adiabatic form (in which each state is described solely by a diquark…
Emergence of the polydeterminant in QCD
Francesco Giacosa, MichaÅ 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,…
Hidden-Strangeness Tetraquarks in the Dynamical Diquark Model
Shahriyar Jafarzade, Richard F. Lebed
The dynamical diquark model describes multiquark exotic hadrons in terms of diquark components nucleated by heavy quarks, and successfully explains multiple features of hidden-char…
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…
