Symanzik Improvement In The Static Quark Potential
A systematic investigation of Symanzik improvement in the gauge field action is performed for the static quark potential in quenched QCD. We consider Symanzik improved gauge field configurations on a 16 × 32 lattice with a relatively coarse lattice spacing of 0.165(2) fm. A matched set of Standard Wilson gauge configurations is prepared at β = 5.74 with the same physical volume and lattice spac...
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 کاملHypercentral Constituent Quark Model and Isospin for the Baryon Static Properties
So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have ta...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
15 صفحه اولTowards String Breaking In The Static Quark Potential
Techniques for revealing the ground state of the static quark potential at large separations are presented and evaluated. The static quark potential is calculated on both unimproved and improved lattice gauge field configurations. Both lattices are 16 ×32 and have approximately the same lattice spacing (≈ 0.18 fm). We show that using an improved gluon action not only gives better rotational sym...
