Radiative corrections to elastic muon-proton scattering at low momentum transfers
Norbert Kaiser, Yong-Hui Lin, Ulf-G. Meißner
We systematically calculate the radiative corrections of order to elastic muon-proton scattering at low momentum transfers. These include vacuum polarization, photon-loop for…
Effects of order on the determination of the Pauli form factor of the -lepton
Norbert Kaiser, Fabian Krinner
We introduce optimal observables to measure the Pauli form factor of the -lepton in the pair-production process from the intensity distribution of the…
Shear Viscosities from Kubo Formalism in a large- Nambu--Jona-Lasinio Model
Robert Lang, Norbert Kaiser, Wolfram Weise
In this work the shear viscosity of strongly interacting matter is calculated within a two-flavor Nambu--Jona-Lasinio model as a function of temperature and chemical potential. The…
Radiative corrections to the charged pion-pair production process {\boldmath} at low energies
N. Kaiser, S. Petschauer
We calculate the one-photon loop radiative corrections to the charged pion-pair production process . In the low-energy region this reaction is governed by the chi…
Shear Viscosity of a Hot Pion Gas
Robert Lang, Norbert Kaiser, Wolfram Weise
The shear viscosity of an interacting pion gas is studied using the Kubo formalism as a microscopic description of thermal systems close to global equilibrium. We implement the ske…
Charmonium potentials: Matching perturbative and lattice QCD
Alexander Laschka, Norbert Kaiser, Wolfram Weise
Central and spin-spin potentials for charmonium, constructed from Nambu-Bethe-Salpeter amplitudes in lattice simulations of full QCD, are matched with results from perturbative QCD…
