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…
