The dynamic of diffractive structure functions    [PDF]

S. Taheri Monfared, Ali N. Khorramian, S. Atashbar Tehrani
We extract diffractive parton distribution functions (DPDFs) and diffractive
structure functions from the most recent H1 and ZEUS diffractive DIS data
obtained by various methods. We consider Pomeron as an object with parton
distribution function, evolving according to the next-to-leading order (NLO)
DGLAP equations within the framework of the `Fixed Flavour Number Scheme'
(FFNS). Having performed a global fit analysis, we achieve a very good
description of all available measurements by introducing a new set of quark
distribution form for the Pomeron. We predict longitudinal and charm proton
diffractive structure function as well. Our results are compared with other
analysis from the literature.
