The dijet invariant mass distribution has been measured in the region between 140 and 1000 GeV/c2, in 1.8 TeV p p¯ collisions. Data collected with the Collider Detector at Fermilab show agreement with QCD calculations. A limit on quark compositeness of Λc>1.3 TeV is obtained. Axigluons with masses between 240 and 640 GeV/c2 are excluded at 95% C.L. if we assume ten open decay channels. Model-independent limits on the production of heavy particles decaying into two jets are also presented.

Preliminary results are presented using the Wide Band photon beam at Fermilab to measure the cross-section of $D^{*\pm}$ and $D^{\pm}$ photoproduction on a Be target over the photon energy range from 100 GeV to 350 GeV....
