Measurement and QCD Analysis of the e+p Cross Section at HERA
نویسنده
چکیده
New measurements of the neutral current deep inelastic scattering (DIS) e + p cross section performed by the H1 collaboration are discussed. The analysis of the structure function F2 at low 2 < Q 2 < 100 GeV 2 leads to a determination of the gluon density based on data taken in 1995-1996. An extension of this analysis towards large y < 0:86 allowed a new determination of the longitudinal proton structure function FL. Recently DIS cross section measurement was extended towards large Q 2 5000 GeV 2 and high x < 0:7 based on about 37 pb ?1 of luminosity collected in the years 1994-1997 .

A measurement is presented of the inclusive ep neutral current cross section, measured single and double differentially, as a function of Q and Bjorken-x. The data used for this measurement were taken by the HERA detector H1 in the 1999-2000 data-taking period, at a centre of mass energy of √ s = 319 GeV and corresponding to an integrated luminosity of L = 65.2 pb−1. An overview of the phenomen...
متن کاملMEASUREMENT AND QCD-ANALYSIS OF THE PROTON STRUCTURE FUNCTION F2(x;Q2) AT HERA
New results on measurements of the proton structure function F 2 (x;Q 2) from H1 and ZEUS at HERA are presented. The data were collected in 1995 and 1996 covering the range 0:16 Q 2 90 GeV 2 and reaching values of x down to 210 ?6. Contrary to observations at values of Q 2 10 GeV 2 , the rise in F 2 with decreasing x is found to be weaker at low Q 2. Conventional NLO QCD evolution equations pro...

A preliminary cross section measurement for neutral and charged current processes in deep inelastic e + p scattering is reported for a range in Q 2 from 200 to 30000 GeV 2. The data were collected by the HERA H1 experiment during the years 1994 { 1997, corresponding to an integrated luminosity of 37 pb ?1. The data are used to compare with electroweak predictions and to test QCD evolutions at h...

The ZEUS inclusive differential cross-section data from HERA-I, for charged and neutral current processes taken with e and e− beams, have been used in a new a NLO QCD analysis to extract the parton distribution functions (PDFs) of the proton within a single experiment. The precision of the high-x gluon determination is improved by using ZEUS differential cross-section data on inclusive jet prod...
متن کاملExclusive Photoproduction at HERA
The exclusive Υ photoproduction, γ p → Υp, has been studied with the ZEUS experiment in ep collisions at HERA using an integrated luminosity of 468 pb−1. The measurement covers the kinematic range 60 < W < 220 GeV and Q2 < 1 GeV2, where W is the photon-proton centre-ofmass energy and Q2 is the photon virtuality. These results, which represent the analysis of the full ZEUS data sample for this c...
