SQRT(S)=540 GEV. 2-JET CROSS SECTION MEASURED BY THE UA1 COLLABORATION AT THE CERN SPS COLLIDER IS USED TO EXTRACT PRODUCT OF STRUCTURE FUNCTIONS S(X1,X2)=F(X1)*F(X2) WHERE F(X)=G(X)+(4/9)(Q(X)+QBAR(X)). THE APPROPRIATE MOMENTUM TRANSFER T(HAT)=-2000GEV**2. OVER THE RANGE X=0.1 TO 0.8 THE STRUCTURE FUNCTION IS PARAMETRISED BY F(X)=6.2*EXP(-9.5X).

$sqrt{S}=540 mathrm{GeV}$。由欧洲核子研究中心（CERN）超质子同步加速器（SPS）对撞机上的UA1合作组测得的双喷注截面，被用于提取结构函数（structure function）的乘积$S(x_1,x_2)=F(x_1)cdot F(x_2)$，其中$F(x)=G(x)+frac{4}{9}left[q(x)+ar{q}(x)
ight]$。对应的动量转移$hat{T}=-2000 mathrm{GeV}^2$。当$xin[0.1,0.8]$时，该结构函数的参数化形式为$F(x)=6.2cdotexp(-9.5x)$。
