# Sum rule for the polarized structure function g{sub 2} corresponding to the moment at n=0

## Abstract

In the small Q{sup 2} region, the sum rule for the polarized structure function g{sub 2} corresponding to the moment at n=0 is derived. This sum rule shows that there is a tight connection among the resonances, the elastic and the continuum in the g{sub 2}. Further, the Born term contribution in this sum rule is proportional to Q{sup 2} and very small compared with that in the corresponding sum rule for the polarized structure function g{sub 1}. However, the Born term contribution divided by Q{sup 2}/2 which also appears in the Schwinger sum rule for the g{sub 2} corresponding to the moment at n=1 has a very similar behavior with that in the sum rule for the g{sub 1} corresponding to the moment at n=0.
