to measure the BFKL intercept\[39-43\]. These processes are illustrated in Figs.8 and 9 respectively where $k_1$ and $k_2$ represent measured jets. In proton-antiproton collisions one chooses $k_{1\perp}, k_{k_2\perp} > M, $ a fixed hard scale, while in deep inelastic scattering $k_{1\perp}$ is chosen to be on the order of Q, the photon virtuality. For the hadron-hadron case

$$\sigma_{2-jet}= f(x_1, x_2, M^2) {e^{(\alpha_P-1)\Delta Y}\over \sqrt{\Delta
Y}}\eqno(5.1)$$

while for deep inelastic scattering

$$\sigma_{jet} = f(x_1,Q^2) {e^{(\alpha_P-1)\ell n x_1/x}\over \sqrt{\ell n
\ x_1/x}}\eqno(5.2)$$

with $x_1$ and $x_2$ being the longitudinal momentum fractions of the measured jets. $\alpha_P-1= {4\alpha N_c\over \pi} \ell n 2$ and the $f$’s in (5.1) and (5.2) are known in terms of the quark and gluon distributions of the proton and antiproton. In (5.1) $\Delta Y$ is the rapidity difference between the two measured jets. One can get a measurement of $\alpha_P-1$ in (5.1) by varying $\Delta Y$ with $x_1, x_2$ and $M^2$ fixed, and this can be done at Fermilab by comparing the inclusive two-jet cross section at different incident energies. In (5.2) one can measure $\alpha_P-1$ by varying $x$ for fixed  $x_1$ and $Q^2.$

Sometime ago H1\[11,12\] presented an analysis showing $\sigma_{jet}$ increasing by about a factor of
