The gluon splitting function at moderately small x
It is widely believed that at small x, the BFKL resummed gluon splitting function should grow as a power of 1/x. But in several recent calculations it has been found to decrease for moderately small-x before eventually rising. We show that this 'dip' structure is a rigorous feature of the P gg splitting function for sufficiently small α s , the minimum occurring formally at log 1/x ∼ 1/ √ α s. ...
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 ...
متن کاملQuark and Gluon Sivers Functions *
The physics of hadron single transverse spin asymmetries is discussed. Possible measurements of both the quark and gluon Sivers functions are proposed.
متن کاملHow Resummation Depresses the Gluon at Small x
We summarize recent progress in the resummation of perturbative evolution at small x. We show that the problem of incorporating BFKL small x logs in GLAP evolution is now completely solved, and that the main effect of small x resummation is to reduce the growth of the gluon at small x in the HERA and LHC regions. Talk at DIS 2006 Tsukuba, Japan, April 2006 to be published in the proceedings Jun...
متن کاملQuantum corrections to the Weizsäcker-Williams gluon distribution function at small x.
We compute the quantum corrections to the gluon distribution function in the background of a non–Abelian Weizsäcker–Williams field. These corrections are valid to all orders in the effective coupling αsμ, where μ 2 denotes the average valence quark color charge squared per unit area. We find ln(1/x) logarithmic corrections to the classical gluon distribution function. The one loop corrections t...
