DETERMINATION OF αs AND mc IN DEEP-INELASTIC SCATTERING
نویسندگان
چکیده
We describe the determination of the strong coupling constant αs(M Z) and of the charm-quark mass mc(mc) in the MS-scheme, based on the QCD analysis of the unpolarized World deep-inelastic scattering data. At NNLO the values of αs(M Z) = 0.1134± 0.0011(exp) and mc(mc) = 1.24± 0.03(exp) +0.03 −0.02(scale) +0.00 −0.07(th) are obtained and are compared with other determinations, and also clarifying discrepancies.

Charm Production in Deep Inelastic Scattering from Threshold to High Q
Charm final states in deep inelastic scattering constitute ∼ 25% of the inclusive cross-section at small x as measured at HERA. These data can reveal important information on the charm and gluon structure of the nucleon if they are interpreted in a consistent perturbative QCD framework which is valid over the entire energy range from threshold to the high energy limit. We describe in detail how...
متن کاملThe 3-, 4-, and 5-flavor NNLO Parton Distributions Functions from Deep-Inelastic-Scattering Data and at Hadron Colliders
We determine the parton distribution functions (PDFs) in a next-to-next-to-leading order (NNLO) QCDanalysis of the inclusive neutral-current deep-inelastic-scattering (DIS) world data combined with the neutrino-nucleon DIS di-muon data and the fixed-target Drell-Yan data. The PDF-evolution is performed in the N f = 3 fixed-flavor scheme and supplementary sets of PDFs in the 4and 5-flavor scheme...
متن کاملProduction of heavy quarks and heavy quarkonia
Uncertainties in the next-to-leading-order calculations of heavyquark (Q) production are investigated. Predictions for total cross sections, single-inclusive distributions of heavy quarks and heavy flavoured hadrons, as well as for QQ̄ correlations, are compared with charm and bottom data. The description of heavy-quarkonium production requires a separation of the short-distance scale of QQ̄ prod...
متن کاملCoefficient functions and open charm production in deep inelastic scattering
It is shown that the problem of double counting in open charm production in DIS can be solved by using the expression for DIS coefficient functions in terms of 2PI diagrams. PACS number(s): 13.60.Hb, 13.85.Ni, 14.65.Dw, 12.38.-t Email address: [email protected] Permanent address 1 Open charm production in deep inelastic scattering (DIS) is a subject of interest from both experimental and theo...
متن کاملFirst Measurement of the Photon Structure Function
The first measurement of F γ 2,c is presented. At low x the measurement indicates a non-zero hadron-like component to F γ 2,c. At large x the measurement constitutes a test of perturbative QCD at next-to-leading order, with only mc and αs as free parameters, with a precision of O(40%). INTRODUCTION For about 20 years measurements of photon structure functions give deep insight into the rich str...
