Shallow states from an EFT analysis of scattering on the lattice
Michael Abolnikov, Lu Meng, Vadim Baru +3
We present an effective field theory (EFT) framework for coupled-channel scattering, applying it to recent lattice QCD results by Alexandrou et al. [Phys. Rev…
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.
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…
Internal structure of the from its light-quark mass dependence
Michael Abolnikov, Vadim Baru, Evgeny Epelbaum +3
We employ a chiral effective field theory-based approach to connect scattering observables at the physical and variable pion masses accessible in lattice QCD simulations. We…
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…
Electromagnetic and gravitational local spatial densities for spin-1 systems
J. Yu. Panteleeva, E. Epelbaum, J. Gegelia +1
The matrix elements of the electromagnetic current and the energy-momentum tensor for sharply localized states of spin-1 systems are considered. Their interpretation as local spati…
