Transverse Momentum and Transverse Momentum Distributions in the MIT Bag Model
A. I. Signal, F. G. Cao
The typical transverse momentum of a quark in the proton is a basic property of any QCD based model of nucleon structure. However, calculations in phenomenological models typically…
Re-examining valence quark spin distributions
A. I. Signal
The observed deep inelastic nucleon spin asymmetries and the spin dependent quark distributions break SU(6) spin - flavour symmetry. In quark models two mechanisms fo…
Perturbative and nonperturbative contributions to the strange quark asymmetry in the nucleon
Guan-Qiu Feng, Fu-Guang Cao, Xin-Heng Guo +1
There are two mechanisms for the generation of an asymmetry between the strange and anti-strange quark distributions in the nucleon: nonperturbative contributions originating from…
The Casimir Effect in Spheroidal Geometries
A. R. Kitson, A. I. Signal
We study the zero point energy of massless scalar and vector fields subject to spheroidal boundary conditions. For massless scalar fields and small ellipticity the zero-point energ…
Strangeness in the Meson Cloud Model
A. I. Signal
I review progress in calculating strange quark and antiquark distributions of the nucleon using the meson cloud model. This progress parallels that of the meson cloud model, which…
Comparison of gluon flux-tube distributions for quark-diquark and quark-antiquark hadrons
F. Bissey, A. I. Signal, D. B. Leinweber
The distribution of gluon fields in hadrons is of fundamental interest in QCD. Using lattice QCD we have observed the formation of gluon flux tubes within 3 quark (baryon) and quar…
