Calculating the gauge-invariant two-point correlation function of gluonic field strengths

The two-point gauge-invariant correlation function of gluonic field strengths, which is the main input in the stochastic vacuum model, is derived by using its relation to the Green functions of oneand two-gluon gluelumps. These Green functions are found by evaluating the path integrals of one and two gluons confined in the field of an infinitely heavy adjoint source. This allows one to obtain a...

Gauge-invariant resummation formalism for two-point correlation functions.

The consistent description of unstable particles, renormalons, or other Schwinger–Dysontype of solutions within the framework of perturbative gauge field theories necessitates the definition and resummation of off-shell Green’s functions, which must respect several crucial physical requirements. A formalism is presented for resummation of off-shell twopoint correlation functions, which is mainl...

Two - Point Angular Correlation Function )

The Two Point Angular Correlation Function (TPACF) is a mathematical equation that has applications in many areas. In our project, the Two Point Angular Correlation Function is used as a way to measure the probability of finding an astronomical body at a given angular distance from another astronomical body. We were given working sequential code as a starting point. The sequential code took in ...

The Two - Point Correlation Function at Redshift

We present the results of a study of the two-point correlation function for a sample of field galaxies taken from the CNOC cluster survey. The sample consists of 144 galaxies within a contiguous region of space subtending 225 square arcminutes. The objects have r-band magnitudes 17.0 ≤ r ≤ 21.7 and redshifts 0.21 ≤ z ≤ 0.53. The median redshift of the sample is z̄ = 0.36. The real space correlat...

Gauge invariant electromagnetic two-point function for heavy-light quark systems.

A gauge invariant electromagnetic two-point function, crucial to the investigations of the violation of isospin symmetry, is derived for heavy-light quark systems. Thus QED can be consistently introduced into the QCD Sum Rule method, which was not previously possible. The origin of mass differences in isospin multiplets has long been of great interest in nuclear and particle physics as a source...
