Low energy constants from the chirally improved Dirac operator D_CI
Christof Gattringer, Philipp Huber, C. B. Lang
The leading order low energy parameters like the pion decay constant or the quark condensate are well-known from "classical" low energy theorems and experiments. It is a challenge,…
Excited meson spectroscopy with chirally improved fermions
T. Burch, C. Gattringer, L. Glozman +4
We present excited meson masses from quenched calculations using chirally improved (CI) quarks at pion masses down to 350 MeV. The salient features of our analysis are the use of a…
Baryon spectroscopy with spatially improved quark sources
Tommy Burch, Christof Gattringer, Leonid Ya. Glozman +4
We study baryons on the lattice with a special focus on excited states. For that purpose we construct several interpolators which differ in their Dirac structure. These interpolato…
Pion form factor with chirally improved fermions
Stefano Capitani, Christof Gattringer, C. B. Lang
We present results for Monte Carlo calculations of the electromagnetic vector and scalar form factors of the pion in a quenched simulation. We work at a lattice spacing of 0.15 fm…
First results from dynamical chirally improved fermions
C. B. Lang, Pushan Majumdar, Wolfgang Ortner
We simulate Quantum Chromodynamics in four Euclidean dimensions with two (degenerate mass) flavors of dynamical quarks. The Dirac operator is the so-called chirally improved operat…
Implementing Hybrid Monte Carlo with stout-smeared chirally improved Dirac operators
C. B. Lang, Pushan Majumdar, Wolfgang Ortner
We discuss our implementation of dynamical Ginsparg-Wilson type fermions using a stout-smeared chirally improved Dirac operator. Such operators have been studied extensively in que…
