Testing Fermion Actions: Scaling in the Schwinger Model
Nils Christian, Karl Jansen, Kei-ichi Nagai +1
We test the scaling behaviour of Wilson, hypercube, maximally twisted mass and overlap fermion actions in dynamical simulations of the 2-dimensional massive Schwinger model. We als…
Scaling test of quenched Wilson twisted mass QCD at maximal twist
K. Jansen, M. Papinutto, A. Shindler +2
We present the results of an extended scaling test of quenched Wilson twisted mass QCD. We fix the twist angle by using two definitions of the critical mass, the first obtained by…
Finite size effects of a pion matrix element
M. Guagnelli, K. Jansen, F. Palombi +3
We investigate finite size effects of the pion matrix element of the non-singlet, twist-2 operator corresponding to the average momentum of non-singlet quark densities. Using the q…
A numerical treatment of Neuberger's lattice Dirac operator
P. Hernandez, K. Jansen, L. Lellouch
We describe in some detail our numerical treatment of Neuberger's lattice Dirac operator as implemented in a practical application. We discuss the improvements we have found to acc…
Some aspects of simulation algorithms for dynamical fermions
Karl Jansen, Beat Jegerlehner, Chuan Liu
Three topics concerning fermion simulation algorithms are discussed: 1.) A performance comparison of the multiboson technique to simulate dynamical fermions and the Kramers equatio…
Strongly Interacting Higgs Sector in the Minimal Standard Model?
Karl Jansen, Julius Kuti, Chuan Liu
The triviality Higgs mass bound is studied {\it without} lattice regulator in the spontaneously broken phase of the four dimensional O(4) symmetric scalar field theory with quartic…
