Introduction to Chiral Perturbation Theory
B. Borasoy
A brief introduction to chiral perturbation theory, the effective field theory of quantum chromodynamics at low energies, is given.
Lattice Simulations for Light Nuclei: Chiral Effective Field Theory at Leading Order
Bugra Borasoy, Evgeny Epelbaum, Hermann Krebs +2
We discuss lattice simulations of light nuclei at leading order in chiral effective field theory. Using lattice pion fields and auxiliary fields, we include the physics of instanta…
Chiral corrections to the Roper mass
B. Borasoy, P. C. Bruns, U. -G. Meißner +1
We analyze the quark mass dependence of the Roper mass to one-loop order in relativistic baryon chiral perturbation theory. The loop integrals are evaluated using infrared regulari…
Eta-eta' mixing in U(3) chiral perturbation theory
Niklas Beisert, Bugra Borasoy
We investigate eta-eta' mixing in infrared regularized U(3) chiral perturbation theory by calculating the eta and eta' masses up to one-loop order. From this analysis it becomes ob…
The electric dipole moment of the neutron in chiral perturbation theory
B. Borasoy
We calculate the electric dipole moments of the neutron and the Lambda within the framework of heavy baryon chiral perturbation theory. They are induced by strong CP-violating term…
Resonances in radiative hyperon decays
B. Borasoy, B. R. Holstein
The importance of resonances for the radiative hyperon decays is examined in the framework of chiral perturbation theory. Low lying baryon resonances are included into the effectiv…
The role of resonances in non-leptonic hyperon decays
B. Borasoy, B. R. Holstein
We examine the importance of resonances for the non-leptonic hyperon decays in the framework of chiral perturbation theory. Lower lying resonances are included into the effective t…
Spherical gauge fields
Bugra Borasoy, Dean Lee
We introduce the spherical field formalism for free gauge fields. We discuss the structure of the spherical Hamiltonian for both general covariant gauge and radial gauge and point…
