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 کاملGluon distribution at moderately low-x from NMC deuteron structure function data
We present some simple methods to find gluon distribution from analysis of deuteron F2 structure function data at moderately lowx. Here we use the leading order(LO) Altarelli -Parisi(AP) evolution equation and New Muon Collaboration (NMC) deuteron F2 structure function data to extract gluon distribution. We also compare our results with those of other authors. PACS:12.38.-t; 12.38.Aw; 13.60.Hb
متن کاملComparison of Nnlo Dis Scheme Splitting Functions with Results from Exact Gluon Kinematics at Small X
We consider the effect of exact gluon kinematics in the virtual photon-gluon impact factor at small x. By comparing with fixed order DIS scheme splitting and coefficient functions, we show that the exact kinematics results match the fixed order results well at each order, which suggests that they allow for an accurate NLL analysis of proton structure functions. We also present, available for th...
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...
