M. Arneodo et al., THE Q(2) DEPENDENCE OF THE STRUCTURE-FUNCTION RATIO F-2(SN) F-2(C) AND THE DIFFERENCE R(SN)-R(C) IN DEEP-INELASTIC MUON SCATTERING/, Nuclear physics. B, 481(1-2), 1996, pp. 23-39
The Q(2) dependence of the structure function ratio F-2(Sn)/F-2(C) for
0.01 < x < 0.75 and 1 < Q(2) < 140 GeV2 is reported. For x < 0.1 the
size of shadowing decreases linearly with In Q(2) and the maximum rate
is about 0.04 at x = 0.01. The rate decreases with x and is compatibl
e with zero for x greater than or equal to 0.1. The difference R(Sn) -
R(C), where R is the ratio of longitudinally to transversely polarise
d virtual photon absorption cross sections, is also given. No dependen
ce on x is seen and the average value is 0.040 +/- 0.021 (stat.) +/- 0
.026 (syst.) at a mean Q(2) of 10 GeV2.
