Tetraquark spectroscopy
Elena Santopinto, Giuseppe Galata'
A complete classification of tetraquark states in terms of the spin-flavor, color and spatial degrees of freedom was constructed. The permutational symmetry properties of both the…
Heavy quarkonium hybrids from Coulomb gauge QCD
Peng Guo, Adam P. Szczepaniak, Giuseppe Galata +2
Using the non-relativisitc reduction of Coulomb gauge QCD we compute spectrum of the low mass hybrid mesons containing a heavy quark-antiquark pair. The gluon degrees of freedom ar…
The physical meaning of scattering matrix singularities in coupled-channel formalisms
S. Capstick, A. Svarc, L. Tiator +8
The physical meaning of bare and dressed scattering matrix singularities has been investigated. Special attention has been attributed to the role of well known invariance of scatte…
Gluelump spectrum from Coulomb gauge QCD
Peng Guo, Adam P. Szczepaniak, Giuseppe Galata +2
We compute the energy spectrum of gluelumps defined as gluonic excitations bound to a localized, static octet source. We are able to reproduce the nontrivial ordering of the spin-p…
Two-component model for the axial form factor of the nucleon
C. Adamuščín, E. Tomasi-Gustafsson, E. Santopinto +1
The axial form factor of the nucleon is studied in a two-component model consisting of a three-quark intrinsic structure surrounded by a meson cloud. The experimental data in the s…
Flavor content of nucleon form factors
R. Bijker, E. Santopinto
The flavor content of nucleon form factors is analyzed using two different theoretical approaches. The first is based on a phenomenological two-component model in which the externa…
