Heaven and Earth: Connecting Jefferson Lab to the Cosmos
J. Piekarewicz
The nuclear equation of state (EOS) serves as the fundamental bridge between atomic nuclei and neutron stars--objects that differ in size by almost 20 orders of magnitude. Central…
Low-energy operators in effective theories
N. P. Mehta, C. Felline, J. R. Shepard +1
Modern effective-theory techniques are applied to the nuclear many-body problem. A novel approach is proposed for the renormalization of operators in a manner consistent with the c…
Novel Methods for Determining Effective Interactions for the Nuclear Shell Model
H. Mueller, J. R. Shepard, J. Piekarewicz
The Contractor Renormalization (CORE) method is applied in combination with modern effective-theory techniques to the nuclear many-body problem. A one-dimensional--yet ``realistic'…
Mean-Field Theory for Spin Ladders Using Angular-Momentum Coupled Bases
J. Piekarewicz, J. R. Shepard
We study properties of two-leg Heisenberg spin ladders in a mean-field approximation using a variety of angular-momentum coupled bases. The mean-field theory proposed by Gopalan, R…
A Plaquette Basis for the Study of Heisenberg Ladders
J. Piekarewicz, J. R. Shepard
We employ a plaquette basis-generated by coupling the four spins in a lattice to a well-defined total angular momentum-for the study of Heisenberg ladders with antiferro…
Comparison of and Quasielastic Scattering
J. Piekarewicz, J. R. Shepard
We formulate -nucleus quasielastic scattering in a manner which closely parallels standard treatments of -nucleus quasielastic scattering. For scattering, new respo…
K-nucleus quasielastic scattering
C. M. Kormanyos, R. J. Peterson, J. R. Shepard +9
K--nucleus quasielastic cross sections measured for a laboratory kaon beam momentum of 705 MeV/ are presented for 3--momentum transfers of 300 and 500 MeV/. The measured…
The Momentum Dependence of the Mixing Amplitude in a Hadronic Model
J. Piekarewicz, A. G. Williams
We calculate the momentum dependence of the mixing amplitude in a purely hadronic model. The basic assumption of the model is that the mixing amplitude is generated by $N{\ba…
