Low energy theorem for virtual Compton scattering and generalized sum rules of the nucleon
M. Gorchtein, A. P. Szczepaniak
We formulate the low energy theorem for virtual Compton scattering off a nucleon and examine its consequences for generalized nucleon polarizabilites. As a result of a new, model i…
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…
A Numerical Approach to Coulomb Gauge QCD
Hrayr H. Matevosyan, Adam P. Szczepaniak, Patrick O. Bowman
We calculate the ghost two-point function in Coulomb gauge QCD with a simple model vacuum gluon wavefunction using Monte Carlo integration. This approach extends the previous analy…
Subcritical solution of the Yang-Mills Schroedinger equation in the Coulomb gauge
D. Epple, H. Reinhardt, W. Schleifenbaum +1
In the Hamiltonian approach to Coulomb gauge Yang-Mills theory, the functional Schroedinger equation is solved variationally resulting in a set of coupled Dyson-Schwinger equations…
What is Measured in Hard Exclusive Electroproduction?
J. T. Londergan, A. P. Szczepaniak
We examine the relation between amplitudes measured in exclusive lepto-production and the quark content of the nucleon. We show that in the limit of high energy and small t, the na…
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…
