“…Also, there is a very good consistency between the results at the same value of x and almost the same value of Q 2 , but different values of ε, as can be seen from the numerical values given in Table II. Both figures also show the results of previous measurements at SLAC [4], by the EMC [13], NMC [14,27,28], and BCDMS [8,9] collaborations at CERN, the E665 [5] collaboration at Fermilab, and the H1 [15][16][17] and ZEUS [18,19] collaborations at DESY. In the region of Q 2 where these overlap with the present results there is good agreement.…”

“…Otherwise, measurements have to be performed for at least two different values of ε (beam energies) at fixed values of x and Q 2 (Rosenbluth separation), or a value for R has to be assumed. Although results for the F 2 structure function have been widely reported [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], in many cases assumptions on the value of R were made. A more limited set of experiments actually performed Rosenbluth separations [4,8,[10][11][12][13][14].…”

“…Recent measurements of the SF have become available, from H1 [24] and ZEUS [25] collaborations ; they complete or correct the previous data near the HERA collider [26]- [29] and [30]- [32] and from fixed target experiments [33]- [37]. They have motivated us to test and compare above mentioned Pomeron models of the proton structure function F 2 (x, Q 2 ) for the widest region of Q 2 and x.…”

A comparative phenomenological analysis of Regge models with and without a hard Pomeron component is performed using a common set of recently updated data. It is shown that the data at small x do not indicate explicitly the presence of the hard Pomeron. Moreover, the models with two soft-Pomeron components (simple and double poles in the angular momentum plane) with trajectories having intercept equal one lead to the best description of the data not only at W > 3 GeV and at small x but also at all x ≤ 0.75 and Q 2 ≤ 30000 GeV 2 .

“…The presence of processes of the type ep → eXp (figure 1) in deep-inelastic scattering (DIS) at low Bjorken-x at the HERA collider [2] offers a uniquely well controlled environment in which to study the QCD properties and structure of diffraction. Several measurements of the semiinclusive cross section for this 'diffractive DIS' process have been made by the H1 [3][4][5][6] and ZEUS [7][8][9][10][11] collaborations. The detailed explanation of hard diffraction has become a major challenge in the development of our understanding of the strong interaction at high energies and low x values [12].…”

A detailed analysis is presented of the diffractive deep-inelastic scattering process ep → eXY , where Y is a proton or a low mass proton excitation carrying a fraction 1−x I P > 0.95 of the incident proton longitudinal momentum and the squared four-momentum transfer at the proton vertex satisfies |t| < 1 GeV 2 . Using data taken by the H1 experiment, the cross section is measured for photon virtualities in the range 3.5 ≤ Q 2 ≤ 1600 GeV 2 , triple differentially in x I P , Q 2 and β = x/x I P , where x is the Bjorken scaling variable. At low x I P , the data are consistent with a factorisable x I P dependence, which can be described by the exchange of an effective pomeron trajectory with intercept α IP (0) = 1.118 ± 0.008 (exp.) +0.029 −0.010 (model). Diffractive parton distribution functions and their uncertainties are determined from a next-to-leading order DGLAP QCD analysis of the Q 2 and β dependences of the cross section. The resulting gluon distribution carries an integrated fraction of around 70% of the exchanged momentum in the Q 2 range studied. Total and differential cross sections are also measured for the diffractive charged current process e + p →ν e XY and are found to be well described by predictions based on the diffractive parton distributions. The ratio of the diffractive to the inclusive neutral current ep cross sections is studied. Over most of the kinematic range, this ratio shows no significant dependence on Q 2 at fixed x I P and x or on x at fixed Q 2 and β.
