Symplectic Effective Field Theory for Nuclear Structure Studies

Autor: D. Kekejian, J. P. Draayer, V. I. Mokeev, C. D. Roberts

A Symplectic Effective Field Theory that unveils the observed emergence of symplectic symmetry in atomic nuclei is advanced. Specifically, starting from a simple extension of the harmonic-oscillator Lagrangian, an effective field theory applied again

Autor: A. N. Hiller Blin, V. I. Mokeev, W. Melnitchouk

Publikováno v: Physical Review

Nucleon resonance contributions to the polarized proton $g_1$ and $g_2$ structure functions are computed from resonance electroexcitation amplitudes extracted from CLAS exclusive meson electroproduction data. Including resonances in the mass range up
