Web{ The dependence 1+(1 y)2 implies a relationship between W 1 and W 2 called the Callan-Gross relation ( W 2 = 2xm pW 1), and provided evidence in favour of the partons being fermions 3 Assuming partons = quarks, conservation of momentum and electric charge dictate for the proton: Z dxx X i f i(x) = 1(14) Z dx[f u(x) f u(x)] = 2(15) Z dx[f d (x ... WebDerive the Callan-Gross relation 2xF 1(x) = F 2(x) What value of the target mass should be used? The ratio 2xF 1/F 2 is shown in Fig. 2 as a function of x. It can be seen that the ratio is, within experimental error, consistent with unity. Figure 2: Ratio of the structure functions 2xF 1(x) and F 2(x). The data are from experiments at SLAC.
