Drell-Hearn-Gerasimov Sum-Rule for the Deuteron in Nuclear Effective Field Theory
Jiunn-Wei Chen, Xiangdong Ji, Yingchuan Li
Abstract
The Drell-Hearn-Gerasimov sum rule for the deuteron is studied in nuclear effective field theory. The low-energy theorem for the spin-dependent Compton amplitude f1(ω) is derived to the next-to-leading order in low-energy expansion. The spin-dependent photodisintegration cross section σP-σA is calculated to the same order, and its contribution to the dispersive integral is evaluated.
