Radiative transitions of hybrid mesons
Shahriyar Jafarzade, Eric S. Swanson
Radiative transitions of hybrid mesons probe nonperturbative gluodynamics, particularly the interplay between quark spin and gluonic excitations, and are of direct relevance to the…
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…
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…
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,…
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…
Phenomenology of light mesons with
Shahriyar Jafarzade
In this thesis, I present the results for light mesons with within an effective hadronic model, the so-called extended Linear Sigma Model (eLSM). This model is based on the…
The role of pomeron states in the Glueball Resonance Gas
Enrico Trotti, Shahriyar Jafarzade
In this note, we present our recent analyses of the thermodynamic properties of the glueball resonance gas. We observe that the dominant contribution to the thermodynamic quantitie…
Three-body decays of and via the Sill distribution
Shahriyar Jafarzade, Enrico Trotti
We present the three-body decays for the resonances and . We use an effective model based on the flavor symmetry and have assumed the Sill distribution fo…
Tensor meson couplings in AdS/QCD
Shahin Mamedov, Zeynab Hashimli, Shahriyar Jafarzade
We study the hadronic and radiative couplings of the meson within the hard- and soft-wall models of AdS/QCD. The results for the tensor meson-nucleon-nucleon coupling (…
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}…

Shahriyar Jafarzade, Arthur Vereijken, Milena Piotrowska +1
While the ground-state tensor () mesons , , , and are well known experimentally and form an almo…

A New Integrable Ising-type Model from 2d =(2,2) Dualities
Shahriyar Jafarzade, Zainab Nazari
We show that the equality of 2d =(2,2) supersymmetric indices in Seiberg-type duality leads to a new integrable Ising-type model. The emergence of the new model is the…
