MC simulation of vector boson production in polarized proton collisions
نویسنده
چکیده
We present a Monte Carlo (MC) study of W and Z0 production of longitudinally polarized proton collisions at a center of mass (CMS) energy of 500GeV. All results were obtained with the SPHINX MC code. We consider two different types of polarized parton distributions with large and small gluon polarization. Various spin asymmetries are found to be sensitive to the shape of the polarized gluon distribution between 0.1 < ∼ x < ∼ 0.5. The asymmetries are approximately constant with respect to the transverse momentum carried by the W and Z0, except if the first moment of the gluon polarization is large. In this case some W asymmetries show a significant variation with transverse momentum. PACS numbers: 13.60Hb, 13.88.+e, 14.20.Dh Submitted to Phys.Rev.D Typeset using REVTEX 1

The MC @ NLO Event Generator ∗
This is the user’s manual of [email protected]. This package is a practical implementation, based upon the HERWIG event generator, of the recently proposed MC@NLO formalism for matching the next-to-leading order calculation of a QCD process with a parton-shower Monte Carlo simulation. The processes of standard-model vector boson pair production in hadronic collisions are available.
متن کاملQCD Corrections to Double and Single Spin Asymmetries in Vector Boson Production at Polarized Hadron Colliders
The production of W and Z0 bosons in collisions of longitudinally polarized protons allows to access various combinations of the polarized quark distributions from the study of double and single spin asymmetries. We compute the O(αs) corrections to these asymmetries as function of the vector boson rapidity y in the hadron–hadron centre-of-mass frame. Detailed studies of the numerical impact of ...
متن کاملSearch for dark matter and supersymmetry in the vector boson fusion topology in proton- proton collisions at CMS
A search for pair production of dark matter candidates and supersymmetry (SUSY) production with two jets in vector-boson fusion (VBF) topology is presented using data collected by the Compact Muon Solenoid (CMS) detector in proton-proton collisions at the Large Hadron Collider (LHC). Final states with no leptons are expected in pair production of dark matter particles or scalar quarks in SUSY c...
متن کاملMeasurements of Diboson Production in pp collisions at 7 TeV with the ATLAS detector
The cross sections of all heavy vector boson pair production processes, namely WW , W Z and ZZ, have been determined with proton-proton collisions at a centre-of-mass energy of 7 TeV with an integrated luminosity of 1.02fb −1. The measured production cross sections are in agreement with prediction from the SM. Limits on anomalous triple gauge boson couplings parameters have been set with ZZ and...
متن کاملCharged Higgs Contribution into tb̄-pair Production in Hadronic Collisions
We investigate the charged Higgs boson contribution into tb̄-pair production in pp-collisions at LHC. It is shown that due to the H-boson exchange the total yield of tb̄ is modified significantly for small and large values of tanβ. However, for the small values of tan β one should expect also the production of right-polarized top quark contrary to pure left-polarized t-quark production through W-...
