Dispersion relations in application to chiral two-nucleon dynamics by Gasparyan, A.M., Lutz, M.F.M., Epelbaum, E.

“…A novel scheme based on the chiral Lagrangian is applied to the nucleon-nucleon interaction close to threshold. Subthreshold partial-wave amplitudes are…”

Compton scattering from chiral dynamics with unitarity and causality by Gasparyan, A.M., Lutz, M.F.M., Pasquini, B.

“…Proton Compton scattering is analyzed with the chiral Lagrangian. Partial-wave amplitudes are obtained by an analytic extrapolation of subthreshold reaction…”

On causality, unitarity and perturbative expansions by Danilkin, I.V., Gasparyan, A.M., Lutz, M.F.M.

“…We present a pedagogical case study how to combine micro-causality and unitarity based on a perturbative approach. The method we advocate constructs an…”

Production of η mesons in nucleon-nucleon collisions by Baru, V., Gasparyan, A.M., Haidenbauer, J., Hanhart, C., Kudryavtsev, A.E., Speth, J.

“…A model calculation for the reaction NN → NNη near-threshold is presented. The η meson production is described by elementary rescattering processes via MN →…”
