From Surface Roughening to Qcd String Theory
نویسنده
چکیده
There exists great interest and considerable effort to explain quark confinement in Quantum Chromodynamics (QCD) from the string theory viewpoint. The ideas of ’t Hooft, Polyakov, Witten, and others, and recent glueball spectrum or QCD string tension calculations in AdS theories are some illustrative examples of these activities. In a somewhat complementary approach, the search for a microscopic mechanism to explain quark confinement in the QCD vacuum continues with vigorous effort. It is useful to note (in loose chronological order) some of the ideas on QCD string formation:

A String Project in Multicolour Qcd
Some old and new evidence for the existence of the string (planar random surfaces) representation of multicolour QCD are reviewed. They concern the random surface representation of the strong coupling expansion in lattice multicolour gauge theory in any dimension. Our old idea of modified strong coupling expansion in terms of planar random surfaces, valid for the physical weak coupling phase of...
متن کاملNano-Structure Roughening on Poly(Lactic Acid)PLA Substrates: Scanning Electron Microscopy (SEM) Surface Morphology Characterization
Scanningelectron microscopy (SEM) has been utilized to examine the morphology and topography alterations in the surface of Poly(Lactic Acid)(PLA) fabrics due to UV/Ozoneirradiation. In the past decade, a growing attention in the usage of “Green Techniques” in industrial applications has been observed owing to many benefits such as low impurities and their relatively low cost to substitute th...
متن کاملDirichlet String Theory and Singular Random Surfaces
We show that string theory with Dirichlet boundaries is equivalent to string theory containing surfaces with certain singular points. Surface curvature is singular at these points. A singular point is resolved in conformal coordinates to a circle with Dirichlet boundary conditions. We also show that moduli parameters of singular surfaces coincide with those of smooth surfaces with boundaries. S...
متن کاملTwo Dimensional QCD is a String Theory
The partition function of two dimensional QCD on a Riemann surface of area A is expanded as a power series in 1/N and A. It is shown that the coefficients of this expansion are precisely determined by a sum over maps from a two dimensional surface onto the two dimensional target space. Thus two dimensional QCD has a simple interpretation as a closed string theory. This work was supported in par...
متن کاملComparative evaluation of niobium surface preparation methods for electrodeposition
To find a suitable treatment in the preparation of Nb surface for platinum electrodeposition, different methods such as thermal oxidation, anodic oxidation, mechanical roughening, and mechanical roughening with subsequent anodic etching were examined. X-ray photoelectron spectroscopy was used to study the chemical composition of depth analysis of the surface. Moreover, in order to examine the m...
