“…For the proton a very extensive data base is available [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. These cross sections usually have been split into the contributions of the charge-and magnetic-form factors G ep (q) and G mp (q) using a Fig.…”

We summarize various analyses of the world data on elastic electron scattering for the determination of the most precise charge rms-radius of the proton. We also present the Zemach moments needed for the interpretation of atomic HFS structure and µ-X-ray experiments.Résumé : Nous passons en revue différentes analyses faites à travers le monde des données de diffusion élastique d'électrons afin de déterminer de la façon la plus précise possible le rayon RMS du proton. Nous présentons également les moments de Zeemach requis dans l'interprétation de la structure atomique HFS et des expériences rayons X.[Traduit par la Rédaction]

“…Higher order terms such as the Schwinger term [33] and additional corrections for vacuum polarization contributions from muon and quark loops were added to the radiative corrections applied to the work of Janssens [17], Bartel [40,58,14], Albercht [59], Litt [35], Goitein [37], Berger [16], and Price [18]. Finally, the small-angle (< 20 o ) data from Walker [13] were excluded since an error was identified in that data.…”

Precision Rosenbluth Measurement of the Proton Elastic Electromagnetic Form Factors and Their Ratio at Q 2 = 2.64, 3.20, and 4.10 GeV 2 Issam A. Qattan Due to the inconsistency in the results of the µpG Ep G M p ratio of the proton, as extracted from the Rosenbluth and recoil polarization techniques, high precision measurements of the e-p elastic scattering cross sections were made at Q 2 = 2.64, 3.20, and 4.10 GeV 2. Protons were detected, in contrast to previous measurements where the scattered electrons were detected, which dramatically decreased ε dependent systematic uncertainties and corrections. A single spectrometer measured the scattered protons of interest while simultaneous measurements at Q 2 = 0.5 GeV 2 were carried out using another spectrometer which served as a luminosity monitor in order to remove any uncertainties due to beam charge and target density fluctuations. The absolute uncertainty in the measured cross sections is ≈ 3% for both spectrometers and with relative uncertainties, random and slope, below 1% for the higher Q 2 protons, and below 1% random and 6% slope for the monitor spectrometer. The extracted electric and magnetic form factors were determined to 4%-7% for G Ep and 1.5% for G M p. The ratio µpG Ep G M p was determined to 4%-7% and showed µpG Ep G M p ≈ 1.0. The results of this work are in agreement with the previous Rosenbluth data and inconsistent with high-Q 2 recoil polarization results, implying a systematic difference between the two techniques. iii My most important acknowledgment is to my caring and loving family and in particular my mother and my father, for without their love and support none of this would have been possible. Their tremendous support all the time motivated, inspired, and kept me alive and helped keep my sane. No words can express my thanks and gratitude to my parents for all that they have gone through and done for me. So, father and mother: this work is dedicated to you with great love and admiration. This thesis is a direct result of the dedication of a great number of people. In particular, I am greatly indebted to my Ph.D. and research advisors Professor Ralph E. Segel from Northwestern University and Dr. John R. Arrington from Argonne National Laboratory, for without their help, steady support, and encouragement this work would not have been possible as well. Their dedication to this work, patience, and "way" too many heated and rousing discussions guided me through too many dark days and tough times. Ralph and John to you I say: I am extremely grateful for all you have done for me and in particular giving me the opportunity to work on a such high-profile experiment. Also I like to thank Professors Heidi Schellman and David Buchholz for their enthusiasm for this work and being a committee members. I gratefully acknowledge the staff of the Accelerator Division, the Hall A technical staff, the members of the survey and cryotarget groups at the Thomas Jefferson National Laboratory for their efforts in making this experiment possible. I like to ackno...

“…The gravitational form factor used in these works is approximated by the dipole form factor A(t) = (1 − t/M 2 d ) −2 , where the dipole mass M d is the one of the four model parameters. The dipole form factor was originally proposed to fit the elastic electron-proton scattering data at large angles [60]. Many studies on the electromagnetic form factors have been done so far, but on the other hand, the gravitational form factors (are also called stress tensor or energy-momentum tensor form factors) are less studied.…”

The cross sections of the high energy proton-proton scattering are studied in a holographic QCD model, focusing on the Regge regime. In our model setup, the involved nonperturbative partonic dynamics is described by the Pomeron exchange, which is realized by applying the Reggeized spin-2 particle propagator together with the proton gravitational form factor obtained from the bottom-up AdS/QCD model. Our model includes three adjustable parameters which are to be fitted by experimental data. We show that both the resulting differential and total cross sections are consistent with data, including the ones recently measured at √ s = 13 TeV by the TOTEM collaboration at the LHC. Our results imply that the present framework works well in the considered TeV scale, and further applications to other high energy scattering processes, in which the involved strong interaction can be approximated by the Pomeron exchange, are possible.
