Vacuum energy in effective field theory of general relativity
E. Epelbaum, J. Gegelia, Ulf-G. Meißner
It is shown to all orders of perturbation theory that in the effective field theory of general relativity the condition of vanishing of the vacuum energy leads to the same value of…
On the definition of the nucleon axial charge density
J. Yu. Panteleeva, E. Epelbaum, J. Gegelia +1
We work out the spatial density distributions corresponding to the axial-vector charge density operator for spin-1/2 systems using states described by sharply localized wave packet…
Vacuum energy in the effective field theory of general relativity with a scalar field
E. Epelbaum, J. Gegelia, Ulf-G. Meißner +1
A consistency condition of general relativity as an effective field theory in Minkowskian background uniquely fixes the value of the cosmological constant. In two-loop calculations…
Gravitational transition form factors in chiral perturbation theory
H. Alharazin, B. -D. Sun, E. Epelbaum +2
The gravitational form factors of the transition from the proton to the resonance are calculated to leading one-loop order using a manifestly Lorentz-invariant formulation of…
Properties of effective massive Yang-Mills theory in the limit of vanishing vector boson mass
J. Gegelia, U. -G. Meißner
Two-loop corrections to the pole mass of the vector boson and the pole masses and the magnetic moments of fermions are calculated in the framework of an effective field theory of m…
Nuclear Forces and Few-Nucleon Studies Based on Chiral Perturbation Theory
W. Gloeckle, E. Epelbaum, U. G. Meissner +3
After a brief review on the status of few--nucleon studies based on conventional nuclear forces, we sketch the concepts of the effective field theory approach constrained by chiral…
