Structure Function Results from ZEUS  [PDF]
A. Kappes
Physics , 2002, DOI: 10.1016/S0920-5632(03)90536-6
Abstract: This contribution presents recent ZEUS results on proton structure functions at HERA. The inclusive phi(1020)-meson cross section was measured, and it was used to determine the s-quark content of the proton. The structure function F_2 was extracted using initial-state radiative events. Neutral and charged current cross sections were used to extract the structure function xF_3 and measure the mass of the W boson, respectively. A NLO QCD fit to ZEUS data and fixed target cross sections was employed to determine the parton density functions of the quarks and of the gluon inside the proton.
Recent Structure Function Results from CCFR  [PDF]
CCFR/NuTeV Collaboration,B. T. Fleming
Physics , 2000,
Abstract: A new structure function analysis of CCFR deep inelastic nu-N and nubar-N scattering data is presented for previously unexplored kinematic regions down to Bjorken x=0.0045 and Q^2=0.3 GeV^2. Comparisons to charged lepton scattering data from NMC and E665 experiments are made and the behavior of the structure function F2_nu is studied in the limit Q^2 -> 0
Two-loop anomalous dimensions for the structure function h1  [PDF]
S. Kumano,M. Miyama
Physics , 1997, DOI: 10.1103/PhysRevD.56.R2504
Abstract: Chiral-odd structure function h1 is expected to be measured in polarized Drell-Yan process. We calculate two-loop anomalous dimensions for h1 in the minimal subtraction scheme. Dimensional regularization and Feynman gauge are used for calculating the two-loop contributions. Our results are important in studying Q^2 dependence of h1.

Proton Structure Function Measurements from HERA  [PDF]
Joerg Gayler
Physics , 2002,
Abstract: Measurements of proton structure functions made in neutral and charged current interactions at HERA are discussed, covering four-momentum transfers Q^2 from about 0.5 GeV^2 to 30000 GeV^2. The results include the rise of the structure function F2 towards small x and electro-weak effects at high Q^2. QCD fits made by the H1 and ZEUS collaborations provide both, parton densities with uncertainties, and precise alpha_s determinations.
Determination of the longitudinal structure function $F_{L}$ at HERA  [PDF]
N. Gogitidze
Physics , 2002, DOI: 10.1088/0954-3899/28/5/303
Abstract: Recent results from the HERA experiment H1 on the longitudinal stucture function $F_{L}$ of the proton are presented. They include proton structure function analyses with particular emphasis on those kinematic regions which are sensitive to $F_{L}$. All results can be consistently described within the framework of perturbative QCD.
New Results from the H1 Collaboration  [PDF]
Andre Schoning
Physics , 2008,
Abstract: After more than 15 years, the operation of the world's unique electron-proton collider HERA ended in June 2007. The data collected by the H1 experiment correspond to a total integrated luminosity of about 0.5 fb$^{-1}$. In 2007 dedicated runs were taken at lower proton beam energies to measure the longitudinal proton structure function $F_L$. In this talk new results, many of them exploiting data taken after the HERA upgrade in the year 2000, and the first measurement of $F_L$ are presented.

Gregorio Bernardi
Physics , 1997, DOI: 10.1063/1.53607
Abstract: Recent deep inelastic results from the H1 collaboration are presented. The topics covered include inclusive diffractive physics, the determination of alpha_S using the event shapes, the study of the hadronic final state at low x with single particles and with jets, the structure function measurements in particular F_2 at low Q^2 and the high Q^2 physics both in neutral and charged current.
Recent structure function results from neutrino scattering at Fermilab  [PDF]
U. K. Yang,T. Adams,A. Alton,C. G. Arroyo,S. Avvakumov,L. de Barbaro,P. de Barbaro,A. O. Bazarko,R. H. Bernstein,A. Bodek et al
Physics , 2000,
Abstract: We report on the extraction of the structure functions F_2 and Delta xF_3 = xF_3(nu)-xF_3(nubar) from CCFR nu_mu-Fe and nubar_mu-Fe different ial cross sections. The extraction is performed in a physics model independent (PMI) way. This first measurement of Delta xF_3, which is useful in testing models of heavy charm production, is higher than current theoretical predictios. The ratio of the F_2 (PMI) values measured in nu_mu and mu scattering is in agreement (within 5%) with the NLO predictions using massive charm production schemes, thus resolving the long-standing discrepancy between the two sets of data. In addition, measurements of F_L (or, equivalently, R) and 2xF_1 are reported in the kinematic region where anomalous nuclear effects in R are observed at HERMES.
Calculation of the Longitudinal Structure Function from Regge-Like Behaviour of the Gluon Distribution Function in Leading Order Approximation at Low x
GR Boroun,B Rezaie,

中国物理快报 , 2007,
Abstract: We present the calculations of FL longitudinal structure functions from DGLAP evolution equation in leading order (LO) at low-x, assuming the Regge-like behaviour of gluon distribution at this limit. The calculated results are compared with the H1 data and QCD fit. It is shown that the obtained results are very close to the mentioned methods. The proposed simple analytical relation for FL provides a t-evolution equation for the determination of the longitudinal structure function at low-x. All the results can consistently bedescribed within the framework of perturbative QCD, which essentially shows increases as x decreases.
