Unintegrated gluon distributions from the color dipole cross section in the BGK saturation model
نویسندگان
چکیده
We evaluate the unintegrated gluon distribution of proton starting from a parametrization color dipole cross section including Dokshitzer–Gribov–Lipatov–Altarelli–Parisi (DGLAP) evolution and saturation effects. To this end, we perform Fourier-Bessel transform σ(x,r)/α(r). At large transverse momentum gluons match so-obtained to logarithmic derivative collinear distribution. check our approach by calculating structure function FL(x,Q2) finding good agreement with HERA data.

Gluon Saturation in the Colour Dipole Model?
We use data on the deep inelastic structure function F2 in order to constrain the cross-section for scattering a colour dipole off a proton. The data seem to prefer parameterisations which include saturation effects. That is they indicate that the strong rise with energy of the dipole cross-section, which holds for small dipoles, pertains only for r < rs(x) where rs(x) decreases monotonically a...
متن کاملGluon Distributions and Fits using Dipole Cross-Sections
I investigate the relationship between the gluon distribution obtained using a dipole model fit to low-x data on F2(x,Q 2) and standard gluons obtained from global fits with the collinear factorization theorem at fixed order. I stress the necessity to do fits of this type carefully, and in particular to include the contribution from heavy flavours to the inclusive structure function. I find tha...
متن کاملUnintegrated gluon distributions in a photon from the CCFM equation in the single loop approximation
The system of CCFM equations for unintegrated parton distributions in a photon is considered in the single loop approximation. We include quarks and non-singular parts of the splitting functions in the corresponding evolution equations. We solve the system of CCFM equations utilising the transverse coordinate representation which diagonalises these equations in the single loop approximation. Th...
متن کاملHeavy Quark Photoproduction in k ⊥ - Factorization Approach
We investigate the heavy quark photoproduction based on the k ⊥-factorization approach, focusing on the results from the saturation model. The deviations in the results using the unintegrated gluon distribution considering the saturation model and the derivative of the collinear gluon distribution are analysed. Total cross sections and p T distributions are analysed in detail, setting the devia...
متن کاملUncertainties on Central Exclusive Scalar Luminosities from the unintegrated gluon distributions
In a previous report we used the Linked Dipole Chain model unintegrated gluon densities to investigate the uncertainties in the predictions for central exclusive production of scalars at hadron colliders. Here we expand this investigation by also looking at other parameterizations of the unintegrated gluon density, and look in more detail on the behavior of these at small k⊥. We confirm our con...
