GLUON CONTRIBUTION TO THE TRANSVERSE SPIN STRUCTURE FUNCTION g2
نویسندگان
چکیده
We consider the twist-3 gluon contribution to the transverse spin structure function g2.We find that the Burkhardt-Cottingham sum rule is satisfied. The additional nonlocal operators appear in the moments of g2 which were absent in previous analysis of Bukhvostov, Kuraev and Lipatov.

Gluon polarization in transversely polarized nucleons and jet spin asymmetries at RHIC
We derive the analog of the Wandzura-Wilczek relation for the light-cone distributions of polarized gluons in a transversely polarized nucleon. The short distance cross-section is entirely due to the intrinsic transverse momenta of gluon in the nucleon, in complete analogy to the quark case. Numerical estimate for the double spin transverse asymmetries at RHIC are presented. PACS. 12.38.Bx, 13....
متن کاملTwist-3 effects in polarized Drell-Yan and semi-inclusive DIS
Spin dependent processes in high energy scatterings provide us with a possibility to extract twist-3 distribution and fragmentation functions which represent quark-gluon correlations inside the hadrons. A well known example is the nucleon’s transverse spin-structure function g2(x,Q ). In this report, we discuss two other processes in which twist-3 distribution functions reveal themselves as a l...

Studying the production or decay processes of heavy quarkonia (the bound state of heavy quark-antiquark) is a powerful tool to test our understanding of strong interaction dynamics and QCD theory. Fragmentation is the dominant production mechanism for heavy quarkonia with large transverse momentum. The fragmentation refers to the production process of a parton with high transverse momentum whic...
متن کاملDiffraction driven steep rise of spin structure function g LT = g 1 + g 2 at small x and DIS sum rules
We derive a unitarity relationship between the spin structure function gLT (x,Q ) = g1(x,Q )+ g2(x,Q ), the LT interference diffractive structure function and the spin-flip coupling of the pomeron to nucleons. Our diffractive mechanism gives rise to a dramatic small-x rise gLT (x,Q ) ∼ g2(x,Q) ∼ ( 1 x )2(1+δg) , where δg is an exponent of small-x rise of the unpolarized gluon density in the pro...
متن کاملThe Gluon Sivers Distribution in D Production at Rhic
The single transverse spin asymmetry in D meson production at RHIC can provide a clean measure of the gluon Sivers distribution function. At intermediate rapidity, D production is largely dominated by the elementary gg → cc̄ channel, where there cannot be any transverse spin transfer. Therefore, any transverse single spin asymmetry observed for D’s produced in pp interactions can only originate ...
