Flavor Twisted Boundary Conditions in the Breit Frame
Fu-Jiun Jiang, Brian C. Tiburzi
We use a generalization of chiral perturbation theory to account for the effects of flavor twisted boundary conditions in the Breit frame. The relevant framework for two light flav…
Chiral Corrections to Hyperon Axial Form Factors
Fu-Jiun Jiang, Brian C. Tiburzi
We study the complete set of flavor changing hyperon axial current matrix elements at small momentum transfer. Using partially quenched heavy baryon chiral perturbation theory, we…
Pion Polarizabilities and Volume Effects in Lattice QCD
Jie Hu, Fu-Jiun Jiang, Brian C. Tiburzi
We use chiral perturbation theory to study the extraction of pion electromagnetic polarizabilities from lattice QCD. Chiral extrapolation formulae are derived for partially quenche…
Current Renormalization in Finite Volume
Jie Hu, Fu-Jiun Jiang, Brian C. Tiburzi
For finite volume field theories with discrete translational invariance, conserved currents can be additively renormalized by infrared effects. We demonstrate this for pions using…
Mixed Action Lattice Spacing Effects on the Nucleon Axial Charge
Fu-Jiun Jiang
We study the nucleon axial charge in the chiral perturbation theory for a mixed lattice action of Ginsparg-Wilson valence quarks and staggered sea quarks. In particular, we investi…
Rotor Spectra, Berry Phases, and Monopole Fields: from Antiferromagnets to QCD
S. Chandrasekharan, F. -J. Jiang, M. Pepe +1
The order parameter of a finite system with a spontaneously broken continuous global symmetry acts as a quantum mechanical rotor. Both antiferromagnets with a spontaneously broken…
