Calculation of Nucleon Electromagnetic Form Factors
LHPC, SESAM Collaborations, : +8
The fomalism is developed to express nucleon matrix elements of the electromagnetic current in terms of form factors consistent with the translational, rotational, and parity symme…
Continuum Extrapolation of Moments of Nucleon Quark Distributions in Full QCD
LHPC, SESAM Collaborations, : +12
Moments of light cone quark density, helicity, and transversity distributions are calculated in unquenched lattice QCD at and using Wilson fermions on $ 16^3 \tim…
Compact QED under scrutiny: it's first order
G. Arnold, B. Bunk, Th. Lippert +1
We report new results from our finite size scaling analysis of 4d compact pure U(1) gauge theory with Wilson action. Investigating several cumulants of the plaquette energy within…
The eta ' signal from partially quenched Wilson fermions
Harmut Neff, Th. Lippert, J. W. Negele +1
We present new results from our ongoing study of flavor singlet pseudoscalar mesons in QCD. Our approach is based on (a) performing truncated eigenmode expansions for the hairpin d…
Calculation of the N to Delta electromagnetic transition matrix element
C. Alexandrou, Ph. de Forcrand, Th. Lippert +5
We present results on the ratio of electric quadrupole to magnetic dipole amplitudes, , for the transition from lattice QCD. We consid…
Numerical Methods for the QCD Overlap Operator: I. Sign-Function and Error Bounds
J. van den Eshof, A. Frommer, Th. Lippert +2
The numerical and computational aspects of the overlap formalism in lattice quantum chromodynamics are extremely demanding due to a matrix-vector product that involves the sign fun…
