p+p→(l++l−)+ anythinganything in a modified Kuti-Weisskopf model

We present here the results of calculations on $\frac{d^2\sigma }{d{Q}^{2}dy}$ and $\frac{d\sigma }{dm}$ for the process $p+p\to (l^{+}+l^{-})+ \mathrm{anything}$ anything using the modified Kuti-Weisskopf model quark-parton distributions. Here $Q^2$ is the mass squared of the dilepton system, $m={\left(Q^2\right)}^{\frac{1}{2}}$ and $y=\frac{2Q_L}{\sqrt{s}}$, with $Q_L$ denoting the longitudinal momentum of the lepton pair in the proton-proton center-of-mass system. The calculations are performed at Brookhaven, NAL, and CERN ISR energies to illustrate the general trend. We also present the single-lepton distributions for this process at NAL and ISR energies.
