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…
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…
Computer Stochastics in Scalar Quantum Field Theory
C. B. Lang
This is a series of lectures on Monte Carlo results on the non-perturbative, lattice formulation approach to quantum field theory. Emphasis is put on 4D scalar quantum field theory…
