A new Monte-Carlo based uncertainty analysis is introduced to quantitatively determine the
predictive ability of QCD sum rules. A comprehensive analysis of ground stateρ-meson and …

Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU(3) gauge symmetry with charges called “color quantum numbers”, is …

… The form D (q 2)= D IR+ D UV, where D IR (q 2)∝(q 2+ M 2)− η and D UV is an infrared …
in D UV. Fixing the form of D UV, we find that the mass parameter M is (1020±1 0 0) MeV. …

We present an unquenched calculation of the quark propagator in Landau gauge with 2​+​
1 flavors of dynamical quarks. We use configurations generated with an improved …

Using lattice quantum chromodynamics (QCD) we perform an unquenched calculation of
the gluon propagator in Landau gauge. We use configurations generated with the AsqTad …

For almost 50 years the structure of the Λ (1405) resonance has been a mystery. Even
though it contains a heavy strange quark and has odd parity, its mass is lower than any other …

… by replacing the u- and d-quark fields in these equations with u-, d-, or s-quark fields
appropriately. For X andA interpolating fields where u, d, and s quarks each occur once, we …

The Landau-gauge gluon propagator is studied using the coarse and fine dynamical MILC
configurations. The effects of dynamical quarks are clearly visible and lead to a reduction of …

The electromagnetic properties of the SU (3)-flavor baryon decuplet are examined within a
lattice simulation of quenched QCD. Electric charge radii, magnetic moments, and magnetic …
