Effective Field Theory for Dilute Fermions with Pairing (2006)
Furnstahl, R. J., Hammer, H. -W., Puglia, S. J.
Effective field theory (EFT) methods for a uniform system of fermions with short-range, natural interactions are extended to include pairing correlations, as part of a program to develop a systematic...
Density Functional Theory for a Confined Fermi System with Short-Range Interaction (2002)
Puglia, S. J., Bhattacharyya, A., Furnstahl, R. J.
Effective field theory (EFT) methods are applied to density functional theory (DFT) as part of a program to systematically go beyond mean-field approaches to medium and heavy nuclei. A system of...
What Do We Know About the Strange Magnetic Radius? (2002)
Hammer, H. -W., Puglia, S. J., Ramsey-Musolf, M. J., Zhu, Shi-Lin
We analyze the q^2-dependence of the strange magnetic form factor, \GMS(q^2), using heavy baryon chiral perturbation theory (HBChPT) and dispersion relations. We find that in HBChPT a significant...
Octet Baryon Charge Radii, Chiral Symmetry and Decuplet Intermediate States (2000)
Puglia, S. J., Ramsey-Musolf, M. J., Zhu, Shi-Lin
We compute the octet baryon charge radii to O(1/Heavy^3) in heavy baryon chiral perturbation theory. We examine the effect of including the decuplet of spin-3/2 baryons explicitly. We find that it...
Chiral Symmetry and the Parity-Violating $NN\pi$ Yukawa Coupling (2000)
Zhu, Shi-Lin, Puglia, S. J., Holstein, B. R., Ramsey-Musolf, M. J.
We construct the complete SU(2) parity-violating (PV) $\pi, N, \Delta$ interaction Lagrangian with one derivative, and calculate the chiral corrections to the PV Yukawa $NN\pi$ coupling constant...
The Nucleon Anapole Moment and Parity-Violating ep Scattering (2000)
Zhu, Shi-Lin, Puglia, S. J., Holstein, B. R., Ramsey-Musolf, M. J.
Parity-violating (PV) interactions among quarks in the nucleon induce a PV $\gamma NN$ coupling, or anapole moment (AM). We compute electroweak gauge-independent contributions to the AM through...
Baryon Octet magnetic moments in $\chi$PT: More on the importance of the Decuplet (1999)
Puglia, S. J., Ramsey-Musolf, M. J.
We address the impact of treating the decuplet of spin-3/2 baryons as an explicit degree of freedom in the chiral expansion of the magnetic moments of the octet of spin-1/2 baryons. We carry out a...
Anomalous Chiral Action from the Path-Integral (1996)
By generalizing the Fujikawa approach, we show in the path-integral formalism: (1) how the infinitesimal variation of the fermion measure can be integrated to obtain the full anomalous chiral action;...
