Meson correlators above deconfinement
S. Datta, F. Karsch, P. Petreczky +1
We review recent progress in studying spectral functions for mesonic observables at finite temperatures, by analysis of imaginary time correlators directly calculated on isotropic…
Matrix product variational formulation for lattice gauge theory
Takanori Sugihara
For hamiltonian lattice gauge theory, we introduce the matrix product anzats inspired from density matrix renormalization group. In this method, wavefunction of the target state is…

We report the status of RBCK calculations on nucleon structure with quenched and dynamical domain wall fermions. The quenched results for the moments of structure functions (< x >_…
Lattice QCD with two dynamical flavors of domain wall quarks
Y. Aoki, T. Blum, N. Christ +11
We present results from the first large-scale study of two flavor QCD using domain wall fermions (DWF), a chirally symmetric fermion formulation which has proven to be very effecti…

We present preliminary results for nucleon dipole moments computed with domain wall fermions. Our main target is the electric dipole moment of the neutron arising from the theta te…
Lattice calculation of the lowest-order hadronic contribution to the muon anomalous magnetic momen

I present quenched domain wall fermion and 2+1 flavor improved Kogut-Susskind fermion calculations of the hadronic vacuum polarization which are used to calculate the ${\cal O}(α^2…
Spontaneous CP violation and quark mass ambiguities
Michael Creutz
I explore the regions of quark masses where CP will be spontaneously broken in the strong interactions. The boundaries of these regions are controlled by the chiral anomaly, which…
Positivity and topology in lattice gauge theory
Michael Creutz
The admissibility condition usually used to define the topological charge in lattice gauge theory is incompatible with a positive transfer matrix.
Charmonia at finite momenta in a deconfined plasma
Saumen Datta, Frithjof Karsch, Peter Petreczky +2
Lattice studies of charmonium systems have indicated that in a deconfined gluonic plasma ground state charmonia survive as bound states upto temperatures \~ 2 Tc. After surveying t…

I discuss recent developments in lattice QCD thermodynamics on the nature of the transition at finite temperature and density, equation of state, screening of static charges and me…
