Two loop expansion of the Schrödinger functional coupling αSF in SU(3) lattice gauge theory

چکیده
The two loop coefficient of the expansion of the Schrödinger functional coupling in terms of the lattice coupling is calculated for the SU(3) Yang-Mills theory. This coefficient is required to relate lattice data to the MS-coupling. As a byproduct of the calculation, the Schrödinger functional is improved to two loop order and the three loop coefficient of the beta function in the SF-scheme is derived.

Two loop lattice expansion of the Schrödinger functional coupling in improved QCD
The contributions of the improved fermion action of Sheikholeslami and Wohlert to the two loop coefficient of the expansion of the Schrödinger functional coupling in terms of the lattice coupling are calculated for the gauge group SU(3). These coefficients are required for the second order relation of lattice data to the MS-coupling. By taking into account all improvement coefficients we are ab...
متن کاملA perturbative determination of O(a) boundary improvement coefficients for the Schrödinger Functional coupling at 1-loop with improved gauge actions
We perturbatively determine O(a) boundary improvement coefficients at 1-loop for the Schrödinger Functional coupling with improved gauge actions. These coefficients are required to implement the 1-loop O(a) improvement in full QCD simulations for the coupling with the improved gauge actions. To this order, lattice artifacts of the step scaling function (SSF) for each improved gauge action are a...
متن کاملTwo - Loop Computation of the Schrödinger Functional in Pure SU ( 3 ) Lattice Gauge Theory
We compute the Schrödinger functional (SF) for the case of pure SU(3) gauge theory at two-loop order in lattice perturbation theory. This allows us to extract the three-loop β-function in the SF-scheme. These results are required to compute the running coupling, the Λ-parameter and quark masses by finite size techniques with negligible systematic errors. In addition, we can now implement two-lo...
متن کاملComputation of the Relation between the Bare Lattice Coupling and the Ms Coupling in Su(n) Gauge Theories to Two Loops
The perturbation expansion of the MS coupling in the SU(N) gauge theory in powers of the bare lattice coupling is extended to two-loop order. A discussion of our results has already been published elsewhere. We here describe the calculation in some detail. It relies on the background eld technique and a recently introduced coordinate space method to evaluate lattice Feynman integrals.
متن کاملSchrödinger functional at negative flavour number
The scaling of the Schrödinger functional coupling is studied numerically and perturbatively for an SU(3) lattice gauge field coupled to an O(a) improved bosonic spinor field. This corresponds to QCD with minus two light flavours and is used as a numerically less costly test case for real QCD. A suitable algorithm is developed, and the influence of the matter fields on the continuum limit and t...
