An Analysis of the Proton Structure Function and the Gluon Distributions at Small x

Communications in Theoretical Physics 2019年第1期71卷 56-66页

Recently, we reported an analysis of Proton structure function at small x based on Taylor approximated DGLAP equations assuming a plausible relationship between the singlet and the gluon distributions. In this paper, we report a generalised version of the previous work. A corresponding study of the suggested gluon distribution is also *** present generalised version of the model for the structure function results in a wider x range of phenomenological validity than the earlier one. A comparison of both the models of the proton structure function and the gluon distribution is made with exact result as well as with the Froissart saturated models of Block, Durand and Mckay.

Design: Retrospective analysis. Setting: East London Hospital. Subjects: 724 women who had maternal serum alphafetoprotein levels measured between 15 to 19 weeks gestation. Main outcome measure: The main outcome measures were defined as any case of preeclampsia, small-for-gestational age (SGA) birth- weight th centile, placental abruption, stillbirth or early neonatal death. Methods: Women with MSAFP > 2.0 Multiples of Median (MoM) were classified as screen positive. Results: 41 (5.7%) women developed preeclampsia. Women with MSAFP > 2.0 Multiples of the Median (MoM) were significantly more likely to develop preeclampsia (p th centile
