On the definitions of the gamma*N -> N* helicity amplitudes
I. G. Aznauryan, V. D. Burkert, T. -S. H. Lee
We present definitions and formulas that may be useful for a consistent computation of helicity amplitudes for the process gamma* N -> N* in theoretical approaches. Of particular i…

Determination of the effective strong coupling constant alpha_{s,g_1}(Q^2) from CLAS spin structure function data
A. Deur, V. Burkert, J. P. Chen +1
We present a new extraction of the effective strong coupling constant α_{s,g_1}(Q^2). The result agrees with a previous determination and extends the measurement of the low and hig…

Experimental study of isovector spin sum rules
A. Deur, P. Bosted, V. Burkert +8
We present the Bjorken integral extracted from Jefferson Lab experiment EG1b for GeV. The integral is fit to extract the twist-4 element which a…
