Presented here are the recent Run II results on the inclusive cross section for W plus \geq n jet(s) (JetClu R=0.4). These cross sections are compared with Run I data and their ratios are measured for inclusive jet multiplicity for n = 0 to 4. The leading order QCD predictions using ALPGEN + HERWIG are compared with the data. Also shown are the comparisons of Diphoton QCD production with next-to-leading order QCD predictions\colon DIPHOX and ResBos. Finally, the \gamma +b and \gamma +c cross sections are presented as a function of photon E_T.
