Hadron Physics Opportunities at FAIR
J. G. Messchendorp, F. Nerling, P. Achenbach +103
This White Paper outlines a coordinated, decade-spanning programme of hadron and QCD studies anchored at the GSI/FAIR accelerator complex. Profiting from intense deuteron, proton a…
Nucleon-nucleon scattering up to next-to-leading order in manifestly Lorentz-invariant chiral effective field theory: low phases and the deuteron
Xiu-Lei Ren, E. Epelbaum, J. Gegelia
Recently the nucleon-nucleon interaction derived using time-ordered perturbation theory in manifestly Lorentz-invariant chiral effective field theory was shown to yield promising r…
Renormalizability and nonrenormalizability of nonlocal potentials
N. Jacobi, A. M. Gasparyan, E. Epelbaum
We consider separable toy models of the nucleon-nucleon interaction inspired by chiral effective field theory. We show that nonlocality of the long-range forces causes the need for…
Zemach radii and nuclear structure effects in hyperfine splitting of Lithium
Yilong Yang, Evgeny Epelbaum, Chen Ji +1
Nuclear structure effects are essential for describing hyperfine splittings from high-precision atomic spectroscopy measurements. These effects are often parametrized by the effect…
Gravitational form factors of the Higgs boson
P. Beißner, B. -D. Sun, E. Epelbaum +1
We calculate the one-loop electroweak corrections to the gravitational form factors of the Higgs boson and discuss the interpretation of the obtained results.
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…
