Book Description
The CDF and D0 experiments have both collected large samples of W and Z bosons with the last Tevatron collider run (1995--1996) using p{anti p} collisions at (square root)s = 1.8 TeV. The author presents the results of QCD studies with vector bosons that cover a large range of transverse momentum space, pT, making this a testing ground for both perturbative and non-perturbative QCD. The measurement of the W and Z cross section, their width, the W and Z transverse momentum distribution and the angular distribution of electrons in W decays are described in this paper.

Book Description
The CDF and D0 collaborations have used recent data taken at the Tevatron to perform QCD tests with W and Z bosons decaying leptonically. D0 measures the production cross section times branching ratio for W and Z bosons. This also gives an indirect measurement of the total width of the W boson: [Lambda][sub W] = 2.126 [+-] 0.092 GeV. CDF reports on a direct measurement of [Lambda][sub W] = 2.19 [+-] 0.19 GeV, in good agreement with the indirect determination and Standard Model predictions. D0's measurement of the differential d[sigma]/dp[sub T] distribution for W and Z bosons decaying to electrons agrees with the combined QCD perturbative and resummation calculations. In addition, the d[sigma]/dp[sub T] distribution for the Z boson discriminates between different vector boson production models. Studies of W + Jet production at CDF find the NLO QCD prediction for the production rate of W + [ge] 1 Jet events to be in good agreement with the data.

Book Description
The 1992--1993 Tevatron collider run ended yesterday. [approx]21 (16)pb[sup [minus]1] of p[bar p] collisions at [radical]S = 1800 GeV were collected at CDF (D0). New measurements of the W and Z cross section x branching ratios indicate that [Gamma](W) is 2.033 [plus-minus] 0.069 [plus-minus] 0.057 GeV. The upper limit for the top quark mass, if it is produced in W decays, is 62 GeV/c[sup 3]. Gauge boson pair production studies are beginning to constrain electro-weak parameters. No neutral gauge bosons with mass> M[sub z] have appeared. Inclusive jet production and angular distribution studies are compared to NLO perturbative QCD predictions. A new topological jet analysis from CDF is sensitive to the low x gluon distribution. The direct photon cross section shows a steeper fall-off with E[sub t] than does the theory prediction. D0 has one candidate t[bar t] event in the dilepton mode. The lower limit on M[sub T[sub op]] has been raised to 99 GeV/c[sup 2].

Book Description
Based around recent lectures given at the prestigious Ritsumeikan conference, the tutorial and expository articles contained in this volume are an essential guide for practitioners and graduates alike who use stochastic calculus in finance.Among the eminent contributors are Paul Malliavin and Shinzo Watanabe, pioneers of Malliavin Calculus. The coverage also includes a valuable review of current research on credit risks in a mathematically sophisticated way contrasting with existing economics-oriented articles.

Book Description
Results in QCD physics at the Tevatron from the D0 and CDF collaborations are presented, including results in jet production, photon production, W/Z bosons plus jets, and heavy-flavor jets. The importance of these topics in tuning Monte-Carlo simulations, constraining the parton distribution functions, and measuring cross sections of QCD processes which contribute significant backgrounds to searches for new and important physics is discussed.
