Fracture Functions: Factorization and Evolution
نویسنده
چکیده
Fracture functions 1 have been introduced to extend the usual QCD improved parton picture of semi-inclusive deep inelastic processes to the low transverse momentum region of phase space, where the target fragmentation contribution becomes important. Trentadue and Veneziano 1 proposed to describe such contribution as a convolution of a new phenomenological distribution, the fracture function, with a hard cross section

B?J/?(?,K) Decays within QCD Factorization Approach
We used QCD factorization for the hadronic matrix elements to show that the existing data, in particular the branching ratios BR ( ?J/?K) and BR ( ?J/??), can be accounted for this approach. We analyzed the decay within the framework of QCD factorization. We have complete calculation of the relevant hard-scattering kernels for twist-2 and twist-3. We calculated this decays in a special scale ...
متن کاملTHE USE OF SEMI INHERITED LU FACTORIZATION OF MATRICES IN INTERPOLATION OF DATA
The polynomial interpolation in one dimensional space R is an important method to approximate the functions. The Lagrange and Newton methods are two well known types of interpolations. In this work, we describe the semi inherited interpolation for approximating the values of a function. In this case, the interpolation matrix has the semi inherited LU factorization.
متن کاملDiffractive Photoproduction in the Framework of Fracture Functions
Recent data on diffractive photoproduction of dijets are analyzed within the framework of fracture functions and paying special attention to the consequences of the use of different rapidity gap definitions in order to identify diffractive events. Although these effects are found to be significant, it is shown that once they are properly taken into account, a very precise agreement between diff...

We calculate next to leading order QCD corrections to semi-inclusive polarized deep inelastic scattering and e + e − annihilation cross sections for processes where the polarization of the identified final-state hadron can also be determined. Using dimensional regularization and the HVBM prescription for the γ 5 matrix, we compute corrections for different spin-dependent observables, both in th...
متن کاملTransverse momentum dependent parton distribution and fragmentation functions with QCD evolution
We assess the current phenomenological status of transverse momentum dependent (TMD) parton distribution functions (PDFs) and fragmentation functions (FFs) and study the effect of consistently including perturbative QCD (pQCD) evolution. Our goal is to initiate the process of establishing reliable, QCD-evolved parametrizations for the TMD PDFs and TMD FFs that can be used both to test TMD facto...
