Measurement of the inclusive triple differential dijet cross section, d3?/dE{sub T}d{sub {eta}1}d{sub {eta}2}, at a center of mass energy √s = 1.8 TeV with the D0 detector during the 1992--1993 run. The sensitivity of this measurement to different parton distribution functions is explored. A comparison of the data to NLO theory using different parton distributions functions indicates the need for a smaller gluon content in the x range accessible at the Tevatron than is predicted by current parton distribution sets.

We report on preliminary measurements of the central, [eta][le] 0.5, inclusive jet and dijet cross sections at[radical]s= 1.8 TeV. Two data sets with integrated luminosities of 91 pb[sup[minus]1] and 14 pb[sup[minus]1] were collected at the Fermilab Tevatron p[ovr p] Collider with the D0 detector. The inclusive jet cross section measured with both data sets and reported as a function of transverse jet energy (35 GeV[le] E[sub T][le] 470 GeV) and the dijet cross section measured with the 91 pb[sup[minus]1] data set and reported as a function of dijet mass (200 GeV[le] M[sub JJ][le] 1 TeV) are in excellent agreement with next-to-leading order QCD. 11 refs., 5 figs.

This thesis presents the analysis of the double differential dijet mass cross section, measured at the D0 detector in Batavia, IL, using p$ar{p}$ collisions at a center of mass energy of √s = 1.96 TeV. The dijet mass was calculated using the two highest pT jets in the event, with approximately 0.7 fb-1 of data collected between 2004 and 2005. The analysis was presented in bins of dijet mass (MJJ) and rapidity (y), and extends the measurement farther in MJJ and y than any previous measurement. Corrections due to detector effects were calculated using a Monte Carlo simulation and applied to data. The errors on the measurement consist of statistical and systematic errors, of which the Jet Energy Scale was the largest. The final result was compared to next-to-leading order theory and good agreement was found. These results may be used in the determination of the proton parton distribution functions and to set limits on new physics.

This thesis presents the analysis of the double differential dijet mass cross section, measured at the D0 detector in Batavia, IL, using p{bar p} collisions at a center of mass energy of (square root)s = 1.96 TeV. The dijet mass was calculated using the two highest p{sub T} jets in the event, with approximately 0.7 fb−1 of data collected between 2004 and 2005. The analysis was presented in bins of dijet mass (M{sub JJ}) and rapidity (y), and extends the measurement farther in M{sub JJ} and y than any previous measurement. Corrections due to detector effects were calculated using a Monte Carlo simulation and applied to data. The errors on the measurement consist of statistical and systematic errors, of which the Jet Energy Scale was the largest. The final result was compared to next-to-leading order theory and good agreement was found.

A preliminary measurement of the inclusive dijet differential cross section obtained from p[anti p] collisions at[radical]s= 1.8 TeV by the CDF collaboration is presented. Results are presented from CDF and D0 for the dijet mass distribution and compared to QCD calculations. The effect of changing the renormalization scale and the choice of the parton density function on the predicted cross section is shown. An estimate of[alpha][sub s] is obtained from the inclusive jet data.

A measurement of the double-differential inclusive dijet production cross section in proton-proton collisions at sqrt(s)=7 TeV is presented as a function of the dijet invariant mass and jet rapidity. The data correspond to an integrated luminosity of 36 inverse picobarns, recorded with the CMS detector at the LHC. The measurement covers the dijet mass range 0.2 TeV to 3.5 TeV and jet rapidities up to.

This paper presents a direct measurement of the differential[ital B][sup+] and[ital B][sup 0] cross sections, [ital d[sigma]/dp[sub T]] in[ital p][ital[anti p]] collisions at[radical]s= 1.8 TeV using a sample of 74[ital pb][sup -1] accumulated by the Collider Detector at Fermilab (CDF). The cross sections are measured in the central pseudorapidity region[vert-bar][eta][vert-bar][lt] 1 for[ital p[sub T]]([ital B])[gt] 6.0 GeV/c by fully reconstructing the[ital B] meson decays[ital B][sup+][r-arrow][ital J/[psi]K[sup+]] and[ital B][sup 0][r-arrow][ital J/[psi]K[sup*0]](892), where[ital J/[psi]][r-arrow][mu][sup+][mu][sup -] and[ital K][sup*0][r-arrow][ital K][sup+][pi][sup -]. The prediction of next-to- leading order QCD is consistent with the shape of the differential cross section but is low by a factor of 2.1[+-]0.2[+-]0.3. The integrated[ital B] meson cross section for[ital p[sub T]]([ital B])[gt] 6.0 GeV/c is determined to be[sigma]([ital B][sup -]= 3. 54[+-]0.22[+-]0.53[mu][ital b].

We present a measurement of the t{bar t} differential cross section with respect to the t{bar t} invariant mass, d[sigma]/dM{sub t{bar t}}, in p{bar p} collisions at √s = 1.96 TeV using an integrated luminosity of 2.7 fb−1 collected by the CDF II experiment. The t{bar t} invariant mass spectrum is sensitive to a variety of exotic particles decaying into t{bar t} pairs. The result is consistent with the standard model expectation, as modeled by PYTHIA with CTEQ5L parton distribution functions.
