Abstract:

The double-Pomeron exchange (DPE) process p̄ + p → p̄′ + X + Y is investigated, where Y is a proton. The ratio of the number of DPE events in the region to the total number of events in the sample was 0.194±0.001±0.012. It was found that the value was lower than the prediction based on Regge factorization by a factor of 1.9 ± 0.2. It was indicated that the formation of a second rapidity gap in a single diffractive (SD) event is relatively unsuppressed. It was observed that the results favor those in which the Regge based shapes of the SD and DPE distributions remain unchanged and only the overall normalization is suppressed.

Abstract:

We report a measurement of the tt production cross section using dilepton events with jets and missing transverse energy in pp collisions at a center-of-mass energy of 1.96 TeV. Using a 197+/-12 pb(-1) data sample recorded by the upgraded Collider Detector at Fermilab, we use two complementary techniques to select candidate events. We compare the number of observed events and selected kinematical distributions with the predictions of the standard model and find good agreement. The combined result of the two techniques yields a tt production cross section of 7.0(+2.4)(-2.1)(stat)+1.6-1.1(syst)+/-0.4(lum) pb.

Abstract:

The resonant substructure of the decay D0→K 0sηπ0 was discussed using Dalitz technique. The study also find dominant contributions from a 0(980)K0s and K*(829)η intermediate states. Using an isobar model averaging of four model was made for additional components and find the amplitude, phase and fit fractions. It was shown that the amplitudes and phases were extracted from the fit, derived from fit fraction which integrates its matrix elements amplitude square and allow phase space division.
