Can Baryon Chiral Perturbation Theory be used to extrapolate lattice data for the moment of the nucleon?
Peter C. Bruns, Ludwig Greil, Rudolf Rödl +1
We discuss the question in the title employing manifestly covariant Baryon Chiral Perturbation Theory and recent high-statistics lattice results published in [1].
Finite Volume corrections to
Ludwig Greil, Philipp Wein, Peter C. Bruns +1
In this paper we calculate the full one-loop finite volume corrections to the quantities within the framework of two-flavor baryon chiral perturbation theory and s…
Chiral behavior of vector meson self energies
Peter C. Bruns, Ludwig Greil, Andreas Schäfer
We employ a chiral Lagrangian framework with three dynamical flavors to calculate the masses of the lowest-lying vector mesons to one loop accuracy, and use the resulting formulae…
Chiral extrapolation of baryon mass ratios
P. C. Bruns, L. Greil, A. Schäfer
We analyze lattice data for octet baryon masses from the QCDSF collaboration employing manifestly covariant Baryon Chiral Perturbation Theory. It is shown that certain combinations…
Nucleon mass and sigma term from lattice QCD with two light fermion flavors
G. S. Bali, P. C. Bruns, S. Collins +16
We analyze Nf=2 nucleon mass data with respect to their dependence on the pion mass down to mpi = 157 MeV and compare it with predictions from covariant baryon chiral perturbation…
Finite volume corrections to the electromagnetic current of the nucleon
Ludwig Greil, Thomas R. Hemmert, Andreas Schäfer
We compute corrections to both the isovector anomalous magnetic moment and the isovector electromagnetic current of the nucleon to in the framework of covariant two-flavor…
The first PDF moments for three dynamical flavors in Baryon Chiral Perturbation Theory
Peter C. Bruns, Ludwig Greil, Andreas Schäfer
We present a calculation of generalized baryon form factors in the framework of three-flavor covariant baryon chiral perturbation theory at leading one-loop order. This is needed f…
