We show that in QCD in the leading twist approximation flavor singlet light cone current-current correlators increase with distances rapidly similar to the correlator of velocities in turbulence and argue that this property is precursor of phase transitions in high energy processes. It is shown that absence of spatial oscillations of current-current correlators follows from asymptotic freedom i...

Correlation functions of the global E 8 symmetry currents in the Heterotic 5-brane theory. We consider the 5-brane placed at one end of the world in the Heterotic E 8 × E 8 theory. The low energy theory is a 6 dimensional (1, 0) superconformal theory with E 8 as a global symmetry. We calculate the two-point correlator of the E 8 current in 6 dimensions and in 4 dimensions after compactification...

We study the correlator of two vector currents in quenched SU(2) lattice gauge theory with a chirally invariant lattice Dirac operator with a constant external magnetic field. It is found that in the confinement phase the correlator of the components of the current parallel to the magnetic field decays much slower than in the absence of a magnetic field, while for other components the correlati...

Three important physical observables, namely, the ratio R(s) = σ(e e→hadrons) σ(e+e−→μ+μ−) , the hadronic decay rate of the Z-boson and the semileptonic branching ratio of the τ -lepton are expressed through the vector and axial-vector current correlators (see, e. g. reviews [4,5]). Perturbative QCD provides reliable predictions for these correlators in the continuum, i.e. sufficiently above th...

Earthbound radio telescopes use for the processing of the received signals a central correlator system. However, for interferometry in space using free flying units, where downlink bandwidth, the power dissipation and space per satellite is limited, a distributed correlator can be more advantageous. This distribution reduces the risk of failures as well. In this paper the proposed architecture ...

We introduce a gauge invariant and string independent two-point fermion correlator which is analyzed in the context of the Schwinger model (QED2). We also derive an effective infrared worldline action for this correlator, thus enabling the computation of its infrared behavior. Finally, we briefly discuss possible perspectives for the string independent correlator in the QED3 effective models fo...
