Distribution of Canonical Determinants in QCD
Andrei Alexandru, C. Gattringer, H. -P. Schadler +2
The distribution of canonical determinants in QCD is determined by means of chiral perturbation theory. For a non-zero quark charge the canonical determinants take complex values.…
Update on the sea contributions to hadron polarizabilities via reweighting
Walter Freeman, Andrei Alexandru, Mike Lujan +1
We have made significant progress on extending lattice QCD calculation of the polarizability of the neutron and other hadrons to include the effects of charged dynamical quarks. Th…
Charm and strange quark masses and from overlap fermions
Yi-Bo Yang, Ying Chen, Andrei Alexandru +8
We use overlap fermions as valence quarks to calculate meson masses in a wide quark mass range on the -flavor domain-wall fermion gauge configurations generated by the RBC and…
Sea contributions to the electric polarizability of the hadrons
Walter Freeman, Andrei Alexandru, Michael Lujan +1
We present a lattice QCD calculation of the polarizability of the neutron and other neutral hadrons that includes the effects of the background field on the sea quarks. This is don…
Chiral Symmetry Breaking and Chiral Polarization: Tests for Finite Temperature and Many Flavors
Andrei Alexandru, Ivan Horváth
It was recently conjectured that, in SU(3) gauge theories with fundamental quarks, valence spontaneous chiral symmetry breaking is equivalent to condensation of local dynamical chi…
Electric polarizability of neutral hadrons from dynamical lattice QCD ensembles
Michael Lujan, Andrei Alexandru, Walter Freeman +1
We present a valence calculation of the electric polarizability of the neutron, neutral pion, and neutral kaon on two dynamically generated nHYP-clover ensembles. The pion masses f…
