Hamiltonian effective field theory study of the ${\mathbf{N}}^{\ast }(1440)$ resonance in lattice QCD

Zhan-Wei Liu, Waseem Kamleh, Derek B. Leinweber +3

We examine the phase shifts and inelasticities associated with the $N^{\ast }(1440)$ Roper resonance and connect these infinite-volume observables to the finite-volume spectrum of lattic…
