On the Infrared Limit of Two Dimensional Qcd
نویسندگان
چکیده
We study the infrared limit of two dimensional QCD, with massless dynamical Dirac fermions that are in the fundamental representation of the gauge group. We find that the theory reduces to a spin generalization of the Calogero model with an additional magnetic coupling which is of the Pauli type.

One of the most serious principles in production theory in economic is the principle of "efficiency". Simply put, efficiency can be defined as the demand that the desired goals (outputs) are achieved with the minimum use of the available resources (inputs). In order to, distinguish the relative efficiency of organizational units with multiple inputs to produce multiple outputs, "Data Envelopmen...
متن کاملOn the QCD corrections to the charged Higgs decay of a heavy quark
On the QCD corrections to the charged Higgs decay of a heavy quark. Using dimensional regularization for both infrared and ultraviolet divergences, we confirm that the QCD corrections to the decay width Γ(t → H + b) are equal to those to Γ(t → W + b) in the limit of a large t quark mass.

Increasing development of nano-technology in optics and photonics by using modern methods of light control in waveguide devices and requiring miniaturization and electromagnetic devices such as antennas, transmission and storage as well as improvement in the electromagnetic tool, have led researchers to use the phenomenon of electromagnetically induced transparency (EIT) and similar phenomena i...

We define pure gauge QCD on an infinite strip of width L. Techniques similar to those used in finite T QCD allow us to relate 3D-observables to pure QCD 2 behaviors. The non triviality of the L → 0 limit is proven and the generalization to four dimensions described. The spectrum of the theory in the small width limit is analyzed and compared to that of the two dimensional theory.

The properties of the gauge invariant two-point quark Green's function are studied in the large-N c limit of two-dimensional QCD. The analysis is done by means of an exact integrodifferential equation. The Green's function is found to be infrared finite, with singularities in the momentum squared variable represented by an infinite number of threshold type branch points with a power-3/2, starti...
