Principles and Possibilities for Bound States in Gauge Theory
Paul Hoyer
Bound states differ from scattering yet are not covered in textbooks on Quantum Field Theory. I discuss a perturbative method for QED and QCD based on canonical quantization. Fully…
Dirac states from the 't Hooft model
Paul Hoyer
The dynamics of a light fermion bound to a heavy one is expected to be described by the Dirac equation with an external potential. The potential breaks translation invariance, wher…
Bound state basics
Paul Hoyer
Perturbative expansions for atoms in QED are developed around interacting states, typically defined by the Schrödinger equation. Calculations are nevertheless done using the standa…
Spin asymmetry at large x_F and k_T
M. Jarvinen
We suggest that the large single spin asymmetries observed at high momentum fractions x_F and transverse momenta k_T of the pion in p^\uparrow p -> π(x_F,k_T)+X arise from the cohe…
Single Spin Asymmetry at Large x_F and k_T
Paul Hoyer, Matti Jarvinen
The large single spin asymmetries observed at high momentum fractions x_F and transverse momenta k_T in p^\uparrow p -> π(x_F,k_T)+X as well as in pp -> Λ^\uparrow(x_F,k_T)+X sugge…
Subprocess Size in Hard Exclusive Scattering
P. Hoyer, J. T. Lenaghan, K. Tuominen +1
The interaction region of hard exclusive hadron scattering can have a large transverse size due to endpoint contributions, where one parton carries most of the hadron momentum. The…
Semi-Exclusive Processes: New Probes of Hadron Structure
S. J. Brodsky, M. Diehl, P. Hoyer +1
We define and study hard ``semi-exclusive'' processes of the form which are characterized by a large momentum transfer between the particles and and a large…
