Scattering of two and three physical pions at maximal isospin from lattice QCD
Matthias Fischer, Bartosz Kostrzewa, Liuming Liu +3
We present the first direct lattice QCD computation of two- and three- scattering quantities that includes an ensemble at the physical point. We study the quark mass d…
The -resonance with physical pion mass from lattice QCD
Matthias Fischer, Bartosz Kostrzewa, Maxim Mai +5
We present the first-ever lattice computation of pi pi-scattering in the I=1 channel with Nf=2 dynamical quark flavours obtained including an ensemble with physical value of the pi…
On the generalised eigenvalue method and its relation to Prony and generalised pencil of function methods
Matthias Fischer, Bartosz Kostrzewa, Johann Ostmeyer +3
We discuss the relation of three methods to determine energy levels in lattice QCD simulations: the generalised eigenvalue, the Prony and the generalised pencil of function methods…
