Hamiltonian SU(N) Lattice Gauge Theories With Exact Vacuum States In 2+1 Dimensions
G. Frichter, D. Robson
We investigate (2+1)-d Hamiltonian lattice gauge theory using a class of Hamiltonians having exactly known vacuum states. These theories are shown to have a wide range of possible…
Relativistic Quark-Antiquark Bound State Problem with Spin-dependent Interactions in Momentum Space
H. -C. Jean, D. Robson, A. G. Williams
The work described in this paper is the first step toward a relativistic three-quark bound-state calculation using a Hamiltonian consistent with the Wigner-Bargmann theorem and mac…
Extreme alpha-clustering in the 18O nucleus
E. D. Johnson, G. V. Rogachev, V. Z. Goldberg +11
The structure of the 18O nucleus at excitation energies above the alpha decay threshold was studied using 14C+alpha resonance elastic scattering. A number of states with large alph…
New solution to the puzzle of the long lifetime of 14C
D. Robson
A new cluster model solution to the long standing nuclear structure problem of describing the anomalously long lifetime of 14C is presented. Related beta-decay data for 14O to stat…
Solution to the Proton Radius Problem
D. Robson
The relationship between the electric form factors for the proton in the rest frame and in the Breit momentum frame is used to provide a value for the difference in the mean square…
Quantum Processes and Energy-Momentum Flow
B. J. Hiley, D. Robson
In this paper we focus on energy flows in simple quantum systems. This is achieved by concentrating on the quantum Hamilton-Jacobi equation. We show how this equation appears in th…
Pion Cloud Contributions to the Proton's Weak Magnetic Form Factor
Simon Capstick, D. Robson
We report on the contributions to the nucleon weak magnetic and electric form factors arising from isospin-breaking form factors. The relativized quark model used in the calculatio…
