Higher Derivative Corrections in Holographic QCD
We consider the effect of the R4 term in type IIA string theory on the supergravity background dual to Nc D4 branes compactified on a circle with supersymmetry breaking boundary conditions. We study the dynamics of D8 branes in this perturbed geometry in the probe approximation. This leads to an analysis of higher derivative corrections in holographic QCD beyond the supergravity approximation. ...
متن کاملThe static quark potential in full QCD ∗
We report results on the static quark potential in two-flavor full QCD. The calculation is performed for three values of lattice spacing a 3 ×48 lattices respectively, at sea quark masses corresponding to mπ/mρ ≈ 0.8–0.6. An RG-improved gauge action and a tadpole-improved SW clover quark action are employed. We discuss scaling of mρ/ √ σ and effects of dynamical quarks on the potential.
متن کاملChiral currents and static properties of nucleons in holographic QCD
We analyze static properties of nucleons in the two flavor holographic QCD model of Sakai and Sugimoto described effectively by a five-dimensional U(2) YangMills theory with the Chern-Simons term on a curved background. The baryons are represented in this model as a soliton, which at a time slice is approximately the BPST instanton with a fixed size. First, we construct a chiral current in four...
متن کاملDetermination of the relativistic corrections to the static inter-quark potential from lattice QCD
We investigate the relativistic corrections to the static potential, i.e. the O(1/m) potential and the O(1/m2) spin-dependent potentials, in SU(3) lattice gauge theory. Utilizing the multilevel algorithm, we obtain a very clean signal for these potentials in the region 0.25 fm . r . 1.2 fm. We confirm long-range nonperturbative contributions in the O(1/m) potential and O(1/m2) spinorbit potenti...
متن کاملrenormalons contribute to the QCD static potential ?
We find that perturbation theory fails to describe the short range static potential as obtained from quenched lattice simulations, at least for source separations r > (6 GeV)−1. The difference between the non-perturbatively determined potential and perturbation theory at short distance is well parameterised by a linear term with a slope of approximately 1.2 GeV2, that is significantly bigger th...
