Applications of the leading-order Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution equations to the combined HERA data on deep inelastic scattering

Journal Article Block, Martin M ; Durand, Loyal ; Ha, Phuoc ; ... - Physical Review. D, Particles Fields

We recently derived explicit solutions of the leading-order Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) equations for the Q{sup 2} evolution of the singlet structure function F{sub s}(x,Q{sup 2}) and the gluon distribution G(x,Q{sup 2}) using very efficient Laplace transform techniques. We apply our results here to a study of the HERA data on deep inelastic ep scattering as recently combined by the H1 and ZEUS groups. We use initial distributions F{sub 2}{sup {gamma}p}(x,Q{sub 0}{sup 2}) and G(x,Q{sub 0}{sup 2}) determined for x<0.1 by a global fit to the HERA data, and extended to x=1 using the shapes of those distributions determined in the CTEQ6Lmore »« less

Multiple parton scattering in nuclei: Modified Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP) evolution for fragmentation functions

Journal Article Weitian, Deng ; Nuclear Science Division, MS 70R0319, Lawrence Berkeley National Laboratory, Berkeley, California 94720 ; Xinnian, Wang - Physical Review. C, Nuclear Physics

Within the framework of generalized factorization of higher-twist contributions to semi-inclusive cross sections of deeply inelastic scattering (DIS) off a large nucleus, multiple parton scattering leads to an effective medium-modified fragmentation function and the corresponding medium-modified DGLAP evolution equations. We extend the study to include gluon multiple scattering and induced quark-antiquark production via gluon fusion. We numerically solve these medium-modified DGLAP (mDGLAP) evolution equations and study the scale (Q{sup 2}), energy (E), length (L), and jet transport parameter (q) dependence of the modified fragmentation functions for a jet propagating in a uniform medium with finite length (a 'brick' problem).

Generalizing the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi Evolution of Fragmentation Functions to the Smallest x Values

Journal Article Albino, S ; Kniehl, B A ; Kramer, G ; ... - Physical Review Letters

An approach valid to any order which unifies the fixed order Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution of fragmentation functions at large x with soft gluon logarithmic resummation at small x is proposed. At lowest order, this approach, implemented with the double logarithmic approximation, reproduces exactly the modified leading logarithm approximation but is more complete due to the degrees of freedom given to the quark sector and the inclusion of the fixed order terms. We find that data from the largest x values to the peak region can be better fitted than with other approaches.

Geometric Scaling from Dokshitzer-Gribov-Lipatov-Altarelli-Parisi Evolution

Journal Article Caola, Fabrizio ; Forte, Stefano - Physical Review Letters

We show that the geometric scaling of the total virtual photon-proton cross section data can be explained using standard linear Dokshitzer-Gribov-Altarelli-Parisi perturbative evolution with generic boundary conditions in a wide kinematic region. This allows us to single out the region where geometric scaling may provide evidence for parton saturation.

Unified BFKL and Gribov-Lipatov-Altarelli-Parisi description of F{sub 2} data

Journal Article Kwiecinski, J ; H. Niewodniczanski Institute of Nuclear Physics, Department of Theoretical Physics, ul. Radzikowskiego 152, 31-342 Krakow ; Martin, A D ; ... - Physical Review, D

We argue that the use of the universal {ital unintegrated} gluon distribution and the k{sub T} (or high energy) factorization theorem provides the natural framework for describing observables at small x. We introduce a coupled pair of evolution equations for the unintegrated gluon distribution and the sea quark distribution which incorporate both the resummed leading ln(1/x) BFKL contributions and the resummed leading ln(Q{sup 2}) GLAP contributions. We solve these unified equations in the perturbative QCD domain using simple parametric forms of the nonperturbative part of the {ital integrated} distributions. With only two (physically motivated) input parameters we find that thismore »« less
