Nonperturbative study of the action parameters for anisotropic-lattice quarks
The anisotropic lattice has proved an invaluable tool for simulations of a variety of physical quantities. The precision calculation of the glueball spectrum was an early application of the approach [1] and it was recognized that anisotropic actions may also be advantageous in heavy quark physics calculations [2]. Correlators of heavy particles such as glueballs and hadrons with a charm or bott...

this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Anisotropic lattice QCD studies of penta-quarks and tetra-quarks
Anisotropic lattice QCD studies of penta-quarks(5Q) with JP = 1/2± and 3/2± are presented at the quenched level together with tetra-quarks(4Q). The standard gauge action at β = 5.75 and O(a) improved quark (clover) action with κ = 0.1410(0.010)0.1440 are employed on the anisotropic lattice with the renormalized anisotropy as/at = 4. The “hybrid boundary condition(HBC)” is adopted to discriminat...

of a continuum field theory. The Lj are higherdimensional operators. The lattice action is adjusted so that the short-distance Kj coefficients vanish, at least approximately. The Fermilab formalism [4] takes Wilson fermions [2] with the clover action [3] and introduces different couplings for space-like and time-like interactions. Ref. [4] considers operators up to dimension five. Ref. [5] adds...
