Proton Structure Measurements and the HERAPDF fit
نویسنده
چکیده
Abstract. New and previously published measurements on the deep inelastic ep scattering cross section by the H1 and ZEUS collaborations are presented. The uncertainties can be significantly reduced by a model independent combination procedure, which treats the systematic error correlations in a coherent way. The combined H1 and ZEUS measurements of the inclusive neutral and charged current cross sections are used to perform a common NLOQCD fit, called HERAPDF 0.1. The resulting set of parton density functions (PDFs) have a much improved experimental uncertainty compared to previous extractions using the uncombined H1 or ZEUS data.

The Structure of the Proton as Measured at HERA
Abstract. Recent measurements that help constrain the structure of the proton from the HERA ep collider experiments H1 and ZEUS are described. Measurements of the proton structure functions F2(x,Q), xF3(x,Q) and FL(x,Q) along with the e+p and e−p charged current cross sections are presented. The precision of the data is further improved by combining the measurements from the two experiments. Th...
متن کاملDesigning an approprate solenoid and magnetic field for the HZDR laser-driven beamline
Nowadays, due to the high costs and large dimensions of the conventional proton accelerators, other optimal methods for producing the proton beam have been studied. Using of Laser-driven proton accelerators is one of the important and new methods. In laser-driven ion acceleration, a highly ultra-intense laser pulse interacts with solid density targets and will create a plasma media that will ac...
متن کاملHERA Inclusive Neutral and Charged Current Cross Sections and a New PDF Fit, HERAPDF2.0∗
In this talk, I present the brand new results from the H1 and ZEUS Collaborations on the combination of all previously published inclusive deep inelastic cross sections at HERA for neutral and charged current e±p scattering for zero beam polarisation and the corresponding parton distributions functions, HERAPDF 2.0, at up to next-to-next-to-leading order (NNLO). The results also include a new p...
متن کاملDose estimation with the calibration of dose-response curve of micronucleus in human peripheral lymphocytes induced by 50MeV proton beams
Background: The purpose of this paper is to establish an easy and reliable biodosimeter protocol to evaluate the biological effects of proton beams. Materials and Methods: Human peripheral blood lymphocytes were irradiated using proton beams (LET: 34.6 keV μm−1), and the chromosome aberrations induced were analyzed using cytokinesis-blocked (CB) micronucleus (MN) assay. To determine th...
متن کاملروش خودسازگار در محاسبه نسبت با استفاده از تابع ساختار و نسبت EMC هستههای He3 و H3
By using the convolution formalism which consists of Fermi motion and binding effect, we investigate the deep inelastic electron scattering from A=3 mirror in the deep-valence region. The initial valence quark input is taken from the GRVs (Gluck, Reya and Vogt) fitting procedure and the next-to-leading order QCD evolution on FP2 (x,Q2) which gives very good fit to the available data in the (x,Q...
