Magnetic polarizability of hadrons from lattice QCD
L. Zhou, F. X. Lee, W. Wilcox +1
We extract the magnetic polarizability from the quadratic response of a hadron's mass shift in progressively small static magnetic fields. The calculation is done on a 24x12x12x24…
Topological Charge Correlators, Spectral Bounds, and Contact Terms
H. Thacker, S. J. Dong, T. Draper +4
The structure of topological charge fluctuations in the QCD vacuum is strongly restricted by the spectral negativity of the Euclidean 2-point correlator for and the prese…
Electric Polarizability of Hadrons
Joe Christensen, Frank X. Lee, Walter Wilcox +1
The electric polarizability of a hadron allows an external electric field to shift the hadron mass. We try to calculate the electric polarizability for several hadrons from their q…
Quenched Chiral Log and Light Quark Mass from Overlap Fermions
Terrence Draper, Shao-Jing Dong, Ivan Horvath +4
We study the quenched chiral behavior of the pion with mass as low as MeV. The calculation is done on a quenched lattice of size and fm with…
The local structure of topological charge fluctuations in QCD
I. Horvath, S. J. Dong, T. Draper +4
We introduce the Dirac eigenmode filtering of topological charge density associated with Ginsparg-Wilson fermions as a tool to investigate the local structure of topological charge…
Excited Baryons and Chiral Symmetry Breaking of QCD
Frank X. Lee
N* masses in the spin-1/2 and spin-3/2 sectors are computed using two non-perturbative methods: lattice QCD and QCD sum rules. States with both positive and negative parity are iso…
