چکیده

We calculate the linear and circular polarization of gluons radiated off top quarks produced in e + e −-annihilations. For typical top pair production energies at the Next-Linear-Collider (NLC) the degree of linear polarization remains close to its soft gluon value of 100% over almost the whole energy spectrum of the gluon. The circular polarization is largest for maximal gluon energies where the linear polarization is smallest. The massive quark results are compared with the corresponding results for the massless quark case.

Gluon Polarization in ee → tt̄G: Polar Angle Dependence and Beam Polarization Effects

We calculate the linear and circular polarization of gluons produced in conjunction with massive quarks in the annihilation process e+e− → qq̄G. The linear polarization is calculated in the hadron event plane as well as in the gluon-beam plane. Beam polarization and polar orientation effects are included in our discussion. For typical top pair production energies at the Next-Linear-Collider (NLC...

Polarization effects in e+e− annihilation processes

We present analytic results for first order radiative QCD corrections to e+e− annihilation processes into quarks and gluons under the special aspect of polarized final state particles. This aspect involves single-spin polarization, gluon polarization, and the correlation between quark spins for massive final state quarks.

توزیع تکانه عرضی و تابش گلویون درفرآیندهای نابودی e‏+e - درانرژی مرکزجرم 60GeV

  We report on an experimental comparison of the characteristics of quark-induced jets based on an analysis of jet events selected from hadronic events at c.m. energy of 60 GeV in e+e- annihilations. The triangle plot shows that the majority are two-jet events. The three-jet events are also present but not as many as two-jet events. The mean transverse momentum is larger for three-jet events th...

The Shape of Polarized Gluon Distributions

The recent high precision SMC data on polarized μp scatterings have again confirmed that very little of the proton spin is carried by quarks. To unravel the mystery of the proton spin structure, it is quite important to know the behavior of the polarized gluon distribution. By using the positivity condition of distribution functions together with the unpolarized and polarized experimental data,...

MC simulation of vector boson production in polarized proton collisions

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 dis...
