On boundary corrections of Lüscher-Weisz string

چکیده
The potential and the density profile of QCD flux-tube are investigated within framework Luscher-Weisz (LW) string action with two boundary terms. Numerical simulations involve 4D SU(3) Yang-Mills LGT at finite temperature. In general, we detect signatures terms considered in LWstring action. Near end Plateau, LW is yielding a static which good agreement lattice data for source separations R ≥ 0.3 fm. However, T/Tc = 0.9, fit to improves attained 0.7 mean-square width energy 0.9 matches well over distance scales 0.5

On Automatic Boundary Corrections*
Many popular curve estimators based on smoothing have diicul-ties caused by boundary eeects. These eeects are visually disturbing in practice and can play a dominant role in theoretical analysis. Local polynomial regression smoothers are known to correct boundary eeects automatically. Some analogs are implemented for density estimation and the resulting estimators also achieve automatic boundar...
متن کاملCorrections and Gauge/String Duality
We make an estimate of the quadratic correction based on gauge/string duality. Like in QCD, it proves to be negative and proportional to the string tension. PACS : 11.25.Pm, 12.38.Lg MPP-2006-31
متن کاملString Unification and Threshold Corrections
The interpretation of the apparent unification of gauge couplings within supersymmetric theories depends on uncertainties induced through heavy particle thresholds. While in standard grand unified theories these effects can be estimated easily, the corresponding calculations are quite complicated in string unified theories and do exist only in models with unbroken E6. We present results for hea...
متن کاملClassical corrections in string cosmology
An important element in a model of non-singular string cosmology is a phase in which classical corrections saturate the growth of curvature in a deSitter-like phase with a linearly growing dilaton (an ‘algebraic fixed point’). As the form of the classical corrections is not well known, here we look for evidence, based on a suggested symmetry of the action, scale factor duality and on conformal ...
متن کاملOn the perturbative corrections around D-string instantons
We study F4-threshold corrections in an eight dimensional S-dual pair of string theories, as a prototype of dual string vacua with sixteen supercharges. We show that the orbifold CFT description of D-string instantons gives rise to a perturbative expansion similar to the one appearing on the fundamental string side. By an explicit calculation, using the Nambu-Goto action in the static gauge, we...
