title: "Table 4" of "The Q**2-dependence of the generalised Gerasimov-Drell-Hearn integral for the deuteron, proton and neutron."

description: The value of the GDH integral for the deuteron, as a function of Q**2, for the full W**2 region for the three generalisations A, B and C.
description: DESY HERA. Measurement of the Gerasimov-Drell-Hearn (GDH) integral for the deuteron, proton and neutron from collisions of 27.57 GeV longitudinally polarised positrons with a longitudinally polarised atomic Deuterium gas target internal to the HERA storage ring in 1998 and 2000, and with an internal polarised atomic Hydrogen target in 1997.. The GDH integral is defined as:. INT[sig_1/2 - sig_3/2]d(nu)/nu , nu_0 & lt; nu & lt; infinity, where sig_1/2 and sig_3/2 are photoabsorption cross sections for total helicity of the photon-nucleon system equal to 1/2 and 3/2, respectively, nu is the photon energy in the target rest frame, nu_0 is the pion production threshold. In the last three tables the generalisation used are:. Generalisation A: INT = CONST*INT(A1(~)*F1)*D(X). Generalisation B: INT = CONST*INT(A1(~)*F1/SQRT(1+Q**2/NU**2))*D(X). Generalisation B: INT = CONST*INT(A1(~)*F1/(1-X))D(X). where CONST = 8*ALPHA*PI**2/Q**2.. The range of the integrals in the tables is from X=0 to X=Q**2/(2*M*NU_0).

Note that the K*0 cross sections are the average of the K*0 and K*BAR0 cross sections.
