چکیده
We report on the first measurement of the angular distributions of final state electrons in pp¯ → γ*/Z → e(+)e(-) + X events produced in the Z boson mass region at √s1.96 TeV. The data sample collected by the CDF II detector for this result corresponds to 2.1 fb(-1) of integrated luminosity. The angular distributions are studied as a function of the transverse momentum of the electron-positron pair and show good agreement with the Lam-Tung relation, consistent with a spin-1 description of the gluon, and demonstrate that, at high values of the transverse momentum, Z bosons are produced via quark-antiquark annihilation and quark-gluon Compton processes.

Dirac Magnetic Monopole Production from Photon Fusion in Proton Collisions
We calculate the lowest order cross–section for Dirac magnetic monopole production from photon fusion (γγ) in pp̄ collisions at √ s = 1.96 TeV, pp collisions at √ s = 14 TeV, and we compare γγ with Drell–Yan (DY) production. We find the total γγ cross–section is comparable with DY at √ s = 1.96 TeV and dominates DY by a factor > ∼ 50 at √ s = 14 TeV. We conclude that both the γγ and DY processes...

Top Quark and Electroweak Results from Dzero
Reported are new top quark and electroweak results from the DØ experiment, which is accumulating luminosity from p¯ p collisions at center-of-mass energy 1.96 TeV (Run II). We study W and Z boson production at the Tevatron to extract a variety of physics. For instance, comparison of the branching fractions B(W → ℓν), where ℓ =e, µ, or τ , tests the universality of the leptonic couplings to the ...

متن کاملATLAS measurement of Electroweak Vector Boson production
The measurements of the Drell-Yan production of W and Z/γ∗ bosons at the LHC provide a benchmark of our understanding of the perturbative QCD and probe the proton structure in a unique way. The ATLAS collaboration has performed new high precision measurements of the double differential cross-sections as a function of the dilepton mass and rapidity. The measurements are compared to state of calc...
متن کاملStudying the underlying event in Drell-Yan and high transverse momentum jet production at the Tevatron
We study the underlying event in proton-antiproton collisions by examining the behavior of charged particles produced in association with a large transverse momentum jet ($ 2:2 fb À1) or with a Drell-Yan lepton pair ($ 2:7 fb À1) in the Z-boson mass region [70 < MðpairÞ < 110 GeV=c 2 ] as measured by CDF at 1.96 TeV center-of-mass energy. We use the direction of the lepton pair or the leading j...
