Abstract:

A search for new physics in the exclusive γ∄T channel was performed. Departure from the expected standard model cross section was found. Limits on two specific models of new physics were defined. Furthermore, the limit in a "pseudomodel-independent" manner was detailed.

Abstract:

We have measured the cross sections d2σ/d P Tdη) for production of isolated direct photons in pp̄ collisions at two different center-of-mass energies, 1.8 TeV and 0.63 TeV, using the Collider Detector at Fermilab. The normalization of both data sets agrees with the predictions of quantum chromodynamics for a photon transverse momentum (PT) of 25 GeV/c, but the shapes versus photon PT do not. These shape differences lead to a significant disagreement in the ratio of cross sections in the scaling variable xT(≡ 2PT/√s). This disagreement in the xT ratio is difficult to explain with conventional theoretical uncertainties such as scale dependence and parton distribution parametrizations. © 2002 The American Physical Society.

Abstract:

We report on measurements of the branching ratios of the decays B+→Xcl0(1P)K+ and B+ →J/ψK+π+π-, where Xcl0(1P)→J/ψγ and J/ψ→μ+μ- in pp collisions at √s= 1.8 TeV. Using a data sample from an integrated luminosity of 110 pb-1 collected by the Collider Detector at Fermilab we measure the branching ratios to be BR(B+→Xcl0(1P) K+)=15.5±5.4(stat)±1.5(syst)±1.3(br)× 10-4 and BR(B+ →J/ψK+π+π-)=6.9 ±1.8(stat)±1.1(syst)±0.4(br)×10-4 where (br) is due to the finite precision on BR(B-→J/ψK+), BR(Xcl0(1P)→J/ψγ)is used to normalize the signal yield, and (syst) encompasses all other systematic uncertainties.

Abstract:

We report a measurement of the diffractive structure function F(D)(jj) of the antiproton obtained from a study of dijet events produced in association with a leading antiproton in pp collisions at sqrt[s] = 630 GeV at the Fermilab Tevatron. The ratio of F(D)(jj) at sqrt[s] = 630 GeV to F(D)(jj) obtained from a similar measurement at sqrt[s] = 1800 GeV is compared with expectations from QCD factorization and other theoretical predictions. We also report a measurement of the xi ( x-Pomeron) and beta ( x of parton in Pomeron) dependence of F(D)(jj) at sqrt[s] = 1800 GeV. In the region 0.035
