Contribution
It demonstrates the factorization property of double parton distribution functions in the small momentum fraction region within leading logarithm approximation.
Findings
Double parton distribution functions exhibit factorization at small momentum fractions.
The analysis is performed within the leading logarithm approximation of perturbative QCD.
The study clarifies the asymptotic behavior of these functions in specific kinematic regions.
Abstract
The double parton distribution functions are investigated in the region of small longitudinal momentum fractions in the leading logarithm approximation of perturbative QCD. It is shown that these functions have the factorization property in the case of one slow and one fast parton.
