Abstract

Multiplicities in semi-inclusive deep-inelastic scattering are presented for each charge state of ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ and ${\mathrm{K}}^{\ifmmode\pm\else\textpm\fi{}}$ mesons. The data were collected by the HERMES experiment at the HERA storage ring using 27.6 GeV electron and positron beams incident on a hydrogen or deuterium gas target. The results are presented as a function of the kinematic quantities ${x}_{\mathrm{B}}$, ${Q}^{2}$, $z$, and ${P}_{h\ensuremath{\perp}}$. They represent a unique data set for identified hadrons that will significantly enhance our understanding of the fragmentation of quarks into final-state hadrons in deep-inelastic scattering.

Abstract

23 pp. (1995)., Charged particle production has been measured in Deep Inelastic Scattering (DIS) events using the ZEUS detector over a large range of $Q~2$ from 10 to $1280 {\rm\ GeV}~2$. The evolution with $Q$ of the charged multiplicity and scaled momentum has been investigated in the current fragmentation region of the Breit frame. The data are used to study QCD \linebreak coherence effects in DIS and are compared with corresponding \eedata in order to test the universality of quark fragmentation.

Abstract

11 pp. (1995)., We demonstrate that the global properties of the “rapidity gap” events, observed at HERA, can be understood based on electron-gluon scattering as the underlying partonic process. Using the measured inclusive structure function F 2 to determine the parameters of the parton model, the diffractive structure function F 2 d is predicted. The ratio of diffractive and inclusive cross sections, R d = Σ d Σ incl ⋍ 1 9 , is determined by the probability of the produced quark-antiquark pair to evolve into a colour singlet state. This colour singlet cluster may fragment into hadrons independently of the proton remnant, yielding the observed gap in rapidity.

Abstract

(1983). doi:10.1103/PhysRevLett.51.443, The results of a high-statistics study of inclusive muon spectra at PETRA are reported. Improved mass limits have been obtained for heavy quarks, heavy leptons, and charged Higgs particles. It is shown that the fragmentation properties of b quarks and c quarks are different, with the mean fragmentation variables 〈zb〉=0.75±0.03±0.06, 〈zc〉=0.46±0.02±0.05 and the average semileptonic branching ratio for the B and C hadrons R(B)=(10.5±1.5±1.3)%, R(C)=(11.5±1.0±1.7)%.

Abstract

61 pp. (1988)., The measurements on properties of jets produced in $e^+e^−$ collisions are reviewed. Special emphasis is given to the experimental information obtained on the space time development of jets and the evidence on coherent gluon emission. The recently published data on jets originating from a special kind of parton are summarized. The extraction of the properties of the original parton from jets is discussed.

Abstract

(1983). doi:10.1103/PhysRevD.27.2063, We show that in a model where fragmentation functions are created from jet calculus followed by recombination, the fragmentation function of charmed quarks into D mesons will fail to peak at low x at currently accessible values of Q2. Likewise, the fragmentation of a c quark into a Λc is much less peaked toward small x than the production of protons by u quarks. The model predicts a magnitude for the fragmentation function much smaller than is experimentally observed.

Abstract

(1978). doi:10.1016/0550-3213(78)90128-1, We have measured the inclusive electroproduction of positive and negative hadrons in the quark fragmentation region using the streamer chamber at DESY. Data are presented in terms of the variable z p = p / v in the kinematic region 1.8 < W < 2.8 GeV and 0.3 < Q 2 < 1.4 GeV 2 . The positive hadron distributions contain a strong proton component. After subtraction of the proton component and elastic rho events, the distribution (1/ σ tot ) d σ /d z p for positive and negative hadrons agrees well with the corresponding distribution from e + e − annihilation (DORIS data). This behaviour supports the validity of the quark-parton model at surprisingly low Q 2 and W .

Abstract

Cross sections for inclusive electroproduction of Ks0's and Λ's have been measured. The Ks0 results are combined with data from electron-positron annihilation and charged K electroproduction to give information on quark fragmentation into strange particles. The longitudinal- and transverse-momentum distributions for Λ's are compared with those of electroproduced protons.

Abstract

Physics reports 276(5-6), 224 - 405 (1996). doi:10.1016/S0370-1573(96)00008-7, The impact of the ARGUS experiment to elementary particle physics is reviewed. More than ten years of data taking has allowed ARGUS to contribute significantly to our understanding of beauty and charmed hadrons, τ Leptons, ϒ mesons, ϒϒ interactions and fragmentation processes. In particular the ARGUS measurements of CKM matrix elements opened up a new window on the Standard Model., Published by Elsevier Science, North-Holland, Amsterdam [u.a.]
