Interpretation of the neutron quantum gravitational states in terms of isospectral potentials
S. Kondratyuk, P. G. Blunden
The recently observed quantum states of neutrons bound in a gravitational field are analyzed in the framework of one-parameter isospectral hamiltonians. Potentials isospectral to t…
Connection between the high energy-scale evolution of the P- and T-odd coupling constant and the strong interaction
P. G. Blunden, S. Kondratyuk
The large energy-scale behaviour of the parity and time-reversal violating (PTV) pion-nucleon coupling constant is analyzed in a model combining renormalization-group techniques an…
Contribution of spin 1/2 and 3/2 resonances to two-photon exchange effects in elastic electron-proton scattering
S. Kondratyuk, P. G. Blunden
We calculate contributions of hadron resonances to two-photon exchange effects in electron-proton scattering. In addition to the nucleon and P33 resonance, the following heavier re…
P- and T-violating form factor
S. Kondratyuk, P. G. Blunden
The form factor of the parity and time-reversal violating (PTV) pion-nucleon interaction is calculated from one-loop vertex diagrams. The degrees of freedom included in the effecti…
Calculation of two-photon exchange effects for production in electron-proton collisions
S. Kondratyuk, P. G. Blunden
We present an evaluation of a two-photon exchange correction to the cross section for unpolarized isobar production in electron-proton collisions, using a relativistic, crossin…
The Adler-Weisberger and Goldberger-Miyazawa-Oehme sum rules as probes of constraints from analyticity and chiral symmetry in dynamical models for pion-nucleon scattering
S. Kondratyuk, K. Kubodera, F. Myhrer +1
The Adler-Weisberger and Goldberger-Miyazawa-Oehme sum rules are calculated within a relativistic, unitary and crossing symmetric dynamical model for pion-nucleon scattering using…
