DOWNLOAD EBOOKWe summarize here the results of the ''counting experiments'' by the CDF Collaboration in the search of t{bar t} production in p{bar p} collisions at (square root)s = 1800 TeV at the Tevatron. We analyze their statistical significance by calculating the probability that the observed excess is a fluctuation of the expected backgrounds, and assuming the excess is from top events, extract a measurement of the t{bar t} production cross-section.

DOWNLOAD EBOOKWe report on the measurement of the t[anti t] production cross section obtained by CDF and D0 experiments with p[anti p] collisions at[radical]s=1. 8 TeV. The analyses presented here refer to[integral] Ldt[approx]11O pb[sup -1] collected at the Fermilab Tevatron collider during the run 1992-96. About 85% of the possible t[anti t] decays have been studied in different channels classified according to the number of high P[sub T] leptons found in the final state. The production cross section has been measured in each individual channel and then combined into a single value for each experiment, which is[sigma][sub tt]= 7.5[sup 1.9][sub 1.6] pb for CDF and[sigma][sub tt]= 5.77[+-] 1.76 pb for D0.

DOWNLOAD EBOOKParticle physics is a science about the symmetries of our world. The Standard Model is the fundamental theory of microworld. Particle dynamics in the Standard Model obeys strict symmetry laws with explicit experimental consequences. Priority problems of particle physics based on the Standard Model are more accurate theoretical predictions, experimental measurements and data analysis, proof of existence or non-existence of supersymmetry, top quark properties, Higgs boson, exotic quark states, and physics of neutrinos. In this collection of articles, many of these problems are discussed. We recommend this book for students, graduate students, and scientists working in the field of high energy physics.

DOWNLOAD EBOOKWe report on the results from the analyses of[ital t][ital[anti t]] decays in[ital dilepton] and[ital lepton+jets] modes with[approx]100 pb[sup -1] of[ital p][ital[anti p]] Collider data at[radical]s= 1.8 TeV collected by the D[null] experiment at the Fermilab Tevatron. We have observed 37[ital t][ital[anti t]] candidate events while the estimated background is 13.4[+-] 3.0 events. The[ital t][ital[anti t]] production cross section has been measured to be 5.2[+-] 1.8 pb at a top quark mass of 170 GeV/c[sup 2].
