Isospin odd πK scattering length
We make use of the chiral two–loop representation of the πK scattering amplitude [J. Bijnens, P. Dhonte and P. Talavera, JHEP 0405 (2004) 036] to investigate the isospin odd scattering length at next-to-next-to-leading order in the SU(3) expansion. This scattering length is protected against contributions of m s in the chiral expansion, in the sense that the corrections to the current algebra r...
متن کاملLattice QCD and Flavor Physics
Now that lattice QCD simulations are able to include effects of light sea quarks, the prospects are good for constraining quark flavor phenomenology. This review talk for particle physics experimentalists begins with an introduction intended to describe broadly the steps of lattice Monte Carlo simulations. The remainder of the talk is a brief survey of recent and ongoing calculations relevant f...
متن کاملThe ππ scattering length from maximally twisted mass lattice QCD
We calculate the s-wave pion-pion scattering length in the isospin I = 2 channel in lattice QCD for pion masses ranging from 270 MeV to 485 MeV using two flavors of maximally twisted mass fermions at a lattice spacing of 0.086 fm. Additionally, we check for lattice artifacts with one calculation at a finer lattice spacing of 0.067 fm. We use chiral perturbation theory at next-to-leading order t...
متن کاملFlavor singlet phenomena in lattice QCD
Flavor singlet combinations of quark operators OΓ S = ūΓu+ d̄Γd+ s̄Γs contribute to many important physical observables in the low energy region of QCD. Experimentally one finds the values of some of these observables to be in sharp contrast to the naive (perturbative) theoretical expectations. This indicates that non perturbative vacuum properties might play a major role in the comprehension of ...
متن کاملLarge - Flavor QCD on the Lattice ∗
We study the nature of the QCD vacuum at general number of flavors N F by numerical simulations on the lattice. Combining the results with those of the perturbation theory, we propose the following picture: 1) For N F ≥ 17, there exists only one IR fixed point at vanishing gauge coupling, i.e., the theory in the continuum limit is trivial. 2) For 16 ≥ N F ≥ 7, there is a non-trivial fixed point...
