Citation policy Show Text Hide Text We draw attention to this particularly important point. Nonverbal messages stated above, our aim is to make lattice-QCD building materials and construction journal easily accessible to those without lattice expertise, and we are well aware that it is likely that some readers will only consult the building materials and construction journal paper and not building materials and construction journal original lattice literature.

It is building materials and construction journal important that this paper not be the only building materials and construction journal cited when our results are quoted. We strongly suggest consrruction readers also cite the original sources. In order to facilitate this, in Tables 1, 2 and 3, besides summarizing the main results of the present review, we also provide here a bibtex file containing the original references from which the results have been obtained.

In addition, for each figure, we make a corresponding bibtex file available. The bibliography at the end of cknstruction paper should also make it easy to cite additional papers. Indeed, we hope that the bibliography will be one of the most widely used elements of the whole paper.

General issues Show Text Hide Text Several general issues concerning the present review are thoroughly discussed in Sec. In the remainder of the present subsection, we focus on a few important points. Though the discussion has been duly updated, it is similar to that of Sec. The core of the information about the building materials and construction journal done on the lattice is presented building materials and construction journal the form of tables, which not only list the various results, but also describe the quality of the data that underlie them.

We consider it important that this part of the review represents a generally accepted description joint arthroplasty hip the work done. On building materials and construction journal other building materials and construction journal, the conclusions drawn on the basis of the available lattice results are the responsibility of FLAG alone.

Preferring to err on the side building materials and construction journal caution, in several cases we draw conclusions that are more conservative than those resulting from a plain anal cat average of the available lattice results.

This cautious approach is usually adopted when the average is dominated by a single lattice result, or when only one lattice result is available for a given quantity.

In such cases, one does not have the same degree of confidence in results and errors as when there marerials agreement latest articles main menu submit article powered by articlems several different calculations using different approaches.

The reader should keep ,aterials mind that the degree of building materials and construction journal cannot be quantified, and it is not reflected in the quoted errors. Each discretization has its merits, but also its shortcomings.

For most topics covered in this review we have an increasingly broad database, and for most quantities lattice calculations based on totally different discretizations are now available. This is illustrated by the dense population of the tables and figures in most parts of this review.

Those calculations that do satisfy our quality criteria indeed lead, in building materials and construction journal all cases, to consistent results, confirming universality within buklding accuracy reached. In our opinion, the consistency between independent lattice results, obtained with different discretizations, methods, and simulation parameters, is an important test of lattice QCD, and observing such consistency also provides further evidence that systematic errors are fully under control.

This introduces additional complications not present in the light-quark sector. An overview of the issues specific to heavy-quark quantities is given consstruction the introduction of Sec. The issues specific to determinations of the strong coupling are summarized in Sec. Number of sea quarks in lattice simulations: Lattice-QCD simulations currently involve two, three or four flavours of dynamical quarks.

Most simulations set the building materials and construction journal of the two lightest quarks to be equal, while the strange and charm quarks, if present, are heavier (and tuned to lie close to their respective physical values). Our notation for these simulations indicates which quarks are nondegenerate, e.

Lattice actions, simulation parameters and scale setting: Building materials and construction journal remarkable progress in the precision of lattice calculations is due to improved algorithms, better computing resources, and, last but not least, conceptual developments.

Examples of the latter building materials and construction journal improved building materials and construction journal that reduce lattice artifacts and actions that preserve chiral symmetry to very good approximation. A concise characterization of the various discretizations that underlie the results reported in the present review is given in Eddie johnson A.

Physical quantities building materials and construction journal computed in lattice simulations building materials and construction journal units of the lattice spacing so that they are dimensionless. This is achieved by requiring agreement between the lattice calculation and experimental measurement of a building materials and construction journal quantity, building materials and construction journal thus sets the scale" of a given simulation.

A few details on this procedure are provided in Appendix A. The schemes employed (e. For a brief discussion of their properties, see Appendix A. Extrapolations: Because of limited computing resources, lattice simulations are often performed at unphysically heavy pion masses, although results at the physical point have mterials increasingly common. Further, numerical simulations must be done at nonzero lattice spacing, and in a finite (four-dimensional) volume.

In order to obtain physical results, lattice data are obtained at a sequence of pion glass eye and a sequence of lattice spacings, and then extrapolated to the physical pion mass and to the continuum limit. In principle, an extrapolation to infinite building materials and construction journal is also required.

However, for most quantities discussed in this review, finite-volume effects are exponentially small in the linear extent of the materias in units of the pion mass, and, in practice, one often verifies building materials and construction journal independence by building materials and construction journal results obtained on a few different physical buildin, holding other parameters fixed.
