First Measurement of Compton Scattering on at HIS
J. Zhou, E. Mancil, M. W. Ahmed +27
The world's first Compton scattering measurements on a He target were performed to probe neutron electromagnetic polarizabilities. Differential cross sections were measured at…
The Unitarity-Limit Expansion for Two Nucleons with Perturbative Pions: Digest and Ideas
Harald W. Griesshammer
In the Unitarity Limit, the NN S-wave binding energies are zero, the scattering lengths infinite, Physics is universal, i.e. insensitive to details of the interactions, and observa…
Scattering Observables from Few-Body Densities and Compton Scattering on 6Li
Alexander Long, Harald W. Griesshammer
The dynamics of scattering on light nuclei is numerically expensive using standard methods. Fortunately, recent developments allow one to factor the relevant quantities for a given…
On Two Nucleons Near Unitarity with Perturbative Pions
Yu Ping Teng, Harald W. Griesshammer
We explore the impact of perturbative pions on the Unitarity Expansion in the two-nucleon S-waves of Chiral Effective Field Theory at next-to-next-to leading order. Pion exchange e…
Using the Transition-Density Formalism in the First Computation of 4He Compton Scattering
Harald W. Griesshammer, Junjie Liao, Judith A. McGovern +2
The method and results of the first theory description of 4He Compton scattering at nuclear energies is presented, with a focus on figures. An upcoming publication [1] contains det…
Compton Scattering on 4He with Nuclear One- and Two-Body Densities
Harald W. Griesshammer, Junjie Liao, Judith A. McGovern +2
We present the first \emph{ab initio} calculation of elastic Compton scattering from 4He. It is carried out to [N3LO] in the expansion of EFT. At this…
