Chiral Properties of Baryon Interpolating Fields
We study the chiral transformation properties of all possible local (non-derivative) interpolating field operators for baryons consisting of three quarks with two flavors, assuming good isospin symmetry. We derive and use the relations/identities among the baryon operators with identical quantum numbers that follow from the combined colour, Dirac and isospin Fierz transformations. These relatio...

متن کاملExcited hadrons from improved interpolating fields
The calculation of quark propagators for Ginsparg-Wilson-type Dirac operators is costly and thus limited to a few different sources. We present a new approach for determining spatially optimized operators for lattice spectroscopy of excited hadrons. Jacobi smeared quark sources with different widths are combined to construct hadron operators with different spatial wave functions. We study the R...
متن کاملOn Interpolating Polynomials over Finite Fields
A set of monomials x a 0 ; : : : ; x ar is called interpolating with respect to a subset S of the nite eld F q , if it has the property that given any pairwise diierent elements x 0 ; : : : ; x r in S and any set of elements y 0 ; : : :; y r in F q there are elements c 0 ; : : :; c r in F q such that y h = P r j=0 c j x a j h for 0 h r. In this paper we address the question of determining inter...
متن کاملInterpolating Orientation Fields: An Axiomatic Approach
We develop an axiomatic approach of vector field interpolation, which is useful as a feature extraction preprocessing step. Two operators will be singled out: the curvature operator, appearing in the total variation minimisation for image restoration and inpainting/disocclusion, and the Absolutely Minimizing Lipschitz Extension (AMLE), already known as a robust and coherent scalar image interpo...
