Polarized Gluon Distribution Function from η′ Production
Using the recently proposed ggη effective vertex, we investigate the production of η from gluon fusion in polarized pp collisions. We show that by measuring ALL in η ′ production, one can extract the polarized gluon distribution ∆G(x,Q) at Q ∼ 1GeV and in a wide range of x.
متن کاملUncertainty of polarized gluon distribution from prompt photon production
Constraint of prompt photon data on the polarized gluon distribution is discussed in terms of uncertainty estimation for polarized parton distribution functions (PDFs). By comparing between uncertainty of the double spin asymmetry AγLL and expected statistical errors at RHIC, we found that the gluon distribution is effectively constrained in the region 0.04 < x T < 0.2 with the data at transver...
متن کاملProduction of η′ from Thermal Gluon Fusion
We study the production of η′ from hadronizing thermal gluons using recently proposed η′ − g − g effective vertex. The η′ yield is found to be sensitive to the initial condition. At RHIC and LHC, the enhancement is large enough to be easily detected.
متن کاملProduction in Polarized pp Scattering and Polarized Gluon Distribution
To extract information about the polarized gluon distribution, ∆G(x,Q), in the nucleons, we propose Λc productions in polarized pp scattering, p+~ p → ~ Λc +X, which will be observed at RHIC experiment starting soon. For this process, we have calculated the spin correlation differential cross section, d∆σ/dp T , and the spin correlation asymmetry defined by ALL ≡ [d∆σ/dpT ]/[dσ/dpT ]. We have f...
متن کاملReactions and Polarized Gluon Distribution
To test the model of the polarized gluon distribution ∆G(x,Q) in the proton, we propose a new process, diffractive Λc productions in polarized pp reactions, which will be observed in the forthcoming RHIC and also the proposed HERA-~ N experiments. The spin correlation between the target proton and the Λc produced in the target fragmentation region largely depends on ∆G(x,Q) and thus, the proces...
