The Structure of the Nucleon
These lectures give an introduction to the structure of the nucleon as seen with the electromagnetic probe. Particular emphasis is put on the form factors, the strangeness content, Compton scattering and polarizabilities, pion photoand electroproduction, the spin structure and sum rules. The existing data are compared to predictions obtained from chiral perturbation theory, dispersion theory an...
متن کاملthe Structure of the Nucleon
In February 2007, the fourth stage of the Mainz Microtron, MAMI-C, started operations with a first experiment. The new Harmonic Double-Sided Microtron delivers an electron beam with energies up to 1.5GeV while preserving the excellent beam quality of the previous stages. The experimental program at MAMI is focused on studies of the hadron structure in the domain of non-perturbative QCD. In this...
متن کاملAxial structure of the nucleon
We review the current status of experimental and theoretical understanding of the axial nucleon structure at low and moderate energies. Topics considered include (quasi)elastic (anti)neutrino–nucleon scattering, charged pion electroproduction off nucleons and ordinary as well as radiative muon capture on the proton. PACS numbers: 11.40.-q, 25.30.Rw, 23.40.-s, 25.30.Pt, 12.39.Fe Submitted to: J....

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولNucleon Structure Functions
New structure function measurements from fixed target experiments and especially HERA are reviewed. The extraction of parton distributions from these measurements is discussed with special emphasis on systematic problems. New information from Drell-Yan and direct photon production experiments are also presented . Finally the present uncertainties of our knowledge on parton distributions and on ...
