| 英文摘要 | In this paper, we report on results for the s-wave scattering length of the pi-K system in the I = 3/2 channel from N-f = 2 + 1 + 1 lattice QCD. The calculation is based on gauge configurations generated by the European Twisted Mass Collaboration with pion masses ranging from about 230 to 450 MeV at three values of the lattice spacing. Our main result reads M(pi)a(0)(3/2,phys) = -0.059(2). Using chiral perturbation theory we are also able to estimate M(pi)a(0)(1/2,phys) = 0.163(3). The error includes statistical and systematic uncertainties, and for the latter in particular errors from the extrapolation to the physical point. |
