The role of the Roper in chiral perturbation theory
(Elsevier B.V., 2011-11-01)
We include the Roper excitation of the nucleon in a version of heavy-baryon chiral perturbation theory recently developed for energies around the delta resonance. We find significant improvement in the P(11) channel. (C) ...

Completing the picture of the Roper resonance
(2015-10-21)
We employ a continuum approach to the three valence-quark bound-state problem in relativistic quantum field theory to predict a range of properties of the proton's radial excitation and thereby unify them with those of ...

Nucleon-to-Roper electromagnetic transition form factors at large Q2
(2019-02-01)
High-precision nucleon-resonance electroproduction data on a large kinematic domain of energy and momentum transfer have proven crucial in revealing novel features of strong interactions within the Standard Model and ...

Records of migration in the exoplanet configurations
(American Astronomical SocietyParaty, 2013)
When compared to our Solar System, many exoplanet systems exhibit quite unusual planet configurations; some of these are hot Jupiters, which orbit their central stars with periods of a few days, others are resonant systems ...
Transition form factors: gamma* plus p -> Delta(1232), Delta(1600)
(Amer Physical Soc, 2019-08-05)
Electroproduction form factors describing the gamma* p -> Delta(+)(1232), Delta(+)(1600) transitions are computed using a fully dynamical diquark-quark approximation to the Poincare-covariant three-body bound-state problem ...
