A relativistic variant of the Wigner function

The Wigner function is a quasiprobability density over phase space (for reviews, see Lee[1], Cohen[2], or Hillery et al.[3]; a quasiprobability is generally not positive semi-definite), so in a quantum field theory setting it is not manifestly Lorentz covariant. Quasiprobabilities are conceptually interesting partly because Arthurs-Kelly type interpretations of positive definite Husimi function...

Greens function of a free massive scalar field on the lattice

We propose a method to calculate the Greens function of a free massive scalar field on the lattice numerically to very high precision. For masses m < 2 (in lattice units) the massive Greens function can be expressed recursively in terms of the massless Greens function and just two additional mass-independent constants.

Generalized relativistic meson wave function.

We study the most general, relativistic, constituent qq meson wave function within a new covariant framework. We find that by including a tensor wave function component, a pure valence quark model is now capable of reproducing not only all static pion data (fπ, 〈r2 π〉) but also the distribution amplitude, form factor (Fπ(Q)), and structure functions. Further, our generalized spin wave function ...

mowing. It is run along the ground on one large wheel which is f ree of the motor operat ing the cutter bar. I t can be tilted to cut up or down slopes and can be pivoted sharply in any direction. It has been found part icularly valuable for cutting around trees, boulders, t raps, creek-bottoms, and other golf course obstructions which formerly required hand cutt ing. The motor scythe, powered ...
