Results onK0 and Λ production ine+e− annihilation at c.m. energies of 14, 22 and 34 GeV are presented. The shape of theK0 and Λ differential cross sections are very similar to each other and to those of π±,K± and\(p(\bar p)\). Scaling violations are observed forK0 production. We obtain a value for the probability to produce strange quark-antiquark pairs relative to that to produce up or down quark-antiquark pairs of 0.35±0.02±0.05. The value ofRh=σ(e+e-→hX)/σµµ is shown to rise steadily with c.m. energy for all particle species. At 34 GeV we find 1.48±0.05K0 and 0.31±0.03 Λ per event. We have searched for possible Λ polarization. The production ofK0's and Λ's in jets is examined as a function ofpT2 and rapidity and compared to that of all charged particles; the yields in two and three jets are also investigated. Results are presented from events with two baryons\((\Lambda ,\bar \Lambda ,por\bar p)\) observed.

10 pp. (1979)., Results on the hadronic final state in e/sup +/e/sup -/ annihilation at 13, 17 and 27.4 GeV are presented. There is no compelling evidence for the existence of the t quark in these data, which are in general agreement with a simple quark parton model. Some tentative indications of QCD effects are observed in the p/sub T//sup 2/ distributions.

(1977). doi:10.1016/0370-2693(77)90684-0, The semileptonic and leptonic decay modes of charmed hadrons produced in e + e − collisions above 4 GeV in the cm have been investigated by selecting events with a single electron plus at least two charged tracks. The electron momentum spectrum peaks near 0.5 GeV/ c with few events above 0.7 GeV/ c . The spectrum excludes large rates for the decays D → e v e and D → e v e π , but is compatible with D → e v e K ∗ (892) , D → e v e K or a mixture of both. The semileptonic branching ratio is obtained both by comparing the inclusive electron cross section with the total cross section attributable to charm, and by studying the fraction of events containing a second electron. The semileptonic charm branching ratios obtained are 0.11 ± 0.03 and 0.16 ± 0.06 respectively. A single event with three electrons and hadrons is found, consistent with the estimated background. The 90% confidence upper limit for σ (e + e − → 3e + hadrons) is 0.1 nb.

(1978). doi:10.1016/0370-2693(78)90183-1, The cross sections for e + e − → e + ( μ + + non showering track + any photons have been measured for cm energies between 3.1 GeV and 5.2 GeV. We observe τ -pair production below the thresholdfor charm production and determine the τ mass to be 1.807 ± 0.020 GeV from a fit to the energy dependence of the cross section. The ration of the leptonic branching ratios B μ / B e = 0.92 ± 0.32 is consistent with eμ-universality. The following branching ratios are determined for a V-A coupling: B(τ → ν τ e ν ) = B(τ → ν τ μ ν ) = 0.182 + 0.028 . B ( τ → ν τ + charged hadron + any photons) = 0.29 ± 0.11, B ( τ → ν τ + three or more charged hadrons + any photons) = 0.35 ± 0.11.

(1983). doi:10.1007/BF01577813, The inclusive production of π± andK± mesons and of protons and antiprotons ine+e− annihilation has been measured at c.m. energies ofW=14, 22 and 34GeV. Using time of flight measurements and Cerenkov counters the full momentum range has been covered. Differential cross sections and total particle yields are given. At particle momenta of 0.4 GeV/c more than 90% of the charged hadrons are pions. With increasing momentum the fraction of pions among the charged hadrons decreases. AtW=34 GeV and a momentum of 5 GeV/c the particle fractions are approximately π±:K±:p,\(\bar p = 0.55:0.3:0.15\). On average an event atW=34 GeV contains 10.3±0.4π±, 2.0±0.2K± and 0.8±0.1p,\(\bar p\). In addition, we present results on baryon correlations using a sample of events where two or more protons and/or antiprotons are observed in the final state.

(1977). doi:10.1016/0370-2693(77)90360-4, The multiplicity distribution of inclusive electron events above 4 GeV cm energy shows two distinct classes of events: two prong no photon and high multiplicity events. If the high multiplicity events are attributed to the semi-leptonic decay of charmed particles the two prong no photon events must come from the weak decay of a different type of particle. The charged K to π ratio was measured for these events. The average number of charged kaons is 0.07 ± 0.06 per two prong event and 0.90 ± 0.18 per multiprong event. Thus the weak current responsible for the low multiplicity events has a small coupling to strange particles.

- Abstract
We present evidence for the production of Ξ·-, Ξ- in e+e- annihilation into hadrons. Our measurements yields: 0.026 ± 0.008 (stat.) ± 0.009 (syst.) Ξ-,Ξ- per hadronic event at W ∼ 34 GeV. Using our previous measurements of Λ, Λ and p,p production we obtain the relative yields (Ξ-, Ξ-/(Λ, Λ = 0.087 ± 0.03 (stat.) ± 0.03 (syst.) and (Ξ-, Ξ-/(p, p = 0.033 ± 0.011 (stat.) ± 0.011 (syst.). © 1983.

- Abstract
The reaction e+e-→e+e-η′(9 58) has been observed by detecting the final state π+π-γ. The two-photon width of the η′ has been measured to be Γ(η′→γγ) = 5.1±0.4±0.7 keV. A search for the ι(1440) has been made in the ρ{variant}0γ final state. An upper limit has been obtained for the product Γ(ι(1440) → γ)gg), B (ι→ρ{variant}0γ) < 1.5 keV (95%CL). © 1984.

- Abstract
We have observed exclusive production of K+K- and KSOKSO pairs and the excitation of the f′(1515) tensor meson in photon-photon collisions. Assuming the f′ to be production in a helicity 2 state, we determine Λ(f′ → γγ) B(f′ → KK) = 0.11 ± 0.02 ± 0.04 keV. The non-strange quark of the f′ is found to be less than 3% (95% CL). For the θ(1640) we derive an upper limit for the product Λ(θ rarr; γγ KK) < 0.03 keV (95% CL). © 1983.

- Abstract
Samples of ∼1,900 identified protons and ∼500 Λ have been used to search for decuplet baryon production in e+e- annihilation at a c.m. energy of 34.4 GeV. The p π+ and Λ π± invariant mass spectra contain no Δ or Σ* signals. Upper limits, at 95% confidence level, are that less than 12% of all p and less than 26% of all Λ come from the decay of doubly charged Δ and singly charged Σ* states respectively. These limits correspond to production rates of

Exclusive production of proton-antiproton pairs by two photon scattering at CM energies between 2.0 GeV and 3.1 GeV has been measured with the TASSO detector at the e+e- storage ring PETRA. The angular distribution is flat within the accepted CM angular range |cos Θ*|≤0.7. The integrated cross section (|cos Θ*|≤0.6) drops from about 4 nb at 2 GeV to less than 0.5 nb above 3 GeV. For the two-photon production of the ηc(2984) and its subsequent decay into proton-antiproton the upper limit Γ(ηc→γγ)·B(η c→pp)

Physics letters / B 338(4), 483-496 (1994). doi:10.1016/0370-2693(94)90804-4, Energy flows in deep inelastic electron-proton scattering are investigated at a centre-of-mass energy of 269 GeV for the range $Q^2 ≥ 10 \text{ GeV}^2$ using the ZEUS detector. A comparison is made between events with and without a large rapidity gap between the hadronic system and the proton direction. The energy flows, corrected for detector acceptance and resolution, are shown for these two classes of events in both the HERA laboratory frame and the Breit frame. From the differences in the shapes of these energy flows we conclude that QCD radiation is suppressed in the large-rapidity-gap eents compared to the events without a large rapidity gap., Published by North-Holland Publ., Amsterdam

The e(+)p neutral-current deep inelastic scattering differential cross-sections d sigma/dQ(2), for Q(2) > 400 GeV2, d sigma/dx and d sigma/dy, for Q(2) > 400, 2500 and 10000 GeV2, have been measured with the ZEUS detector at HERA. The data sample of 47.7 pb(-1) was collected at a center-of-mass energy of 300 GeV. The cross-section, d sigma/dQ(2), falls by six orders of magnitude between Q(2) = 400 and 40000 GeV2. The predictions of the Standard Model are in very good agreement with the data. Complementing the observations of time-like Z(0) contributions to fermion-antifermion annihilation! the data provide direct evidence for the presence of Z(0) exchange in the space-like region explored by deep inelastic scattering.

Beauty production in events containing two muons in the final state has been measured with the ZEUS detector at HERA using an integrated luminosity of 114 pb-1. A low transverse-momentum threshold for muon identification, in combination with the large rapidity coverage of the ZEUS muon system, gives access to almost the full phase space for beauty production. The total cross section for beauty production in ep collisions at sqrt(s)= 318 GeV has been measured to be sigma_tot(ep -> bbbar X) = 13.9 +- 1.5(stat.) +4.0 -4.3(syst.) nb. Differential cross sections and a measurement of bbbar correlations are also obtained, and compared to other beauty cross-section measurements, Monte Carlo models and next-to-leading-order QCD predictions., 33 pages, 11 figures

In a search for signatures of physics processes beyond the Standard Model, various eeqq vector contact–interaction hypotheses have been tested using the high– $Q^2$ deep inelastic neutral–current $e^+p$ scattering data collected with the ZEUS detector at HERA. The data correspond to an integrated luminosity of $47.7\,{\rm pb}^{-1}$ of $e^+p$ interactions at 300 GeV center–of–mass energy. No significant evidence of a contact–interaction signal has been found. Limits at the 95% confidence level are set on the contact–interaction amplitudes. The effective mass scales $\Lambda$ corresponding to these limits range from 1.7 TeV to 5 TeV for the contact–interaction scenarios considered.

Physical review / D 78(7), 072001 (2008). doi:10.1103/PhysRevD.78.072001, Photoproduction of beauty quarks in events with two jets and an electron associated with one of the jets has been studied with the ZEUS detector at HERA using an integrated luminosity of 120pb^-1. The fractions of events containing b quarks, and also of events containing c quarks, were extracted from a likelihood fit using variables sensitive to electron identification as well as to semileptonic decays. Total and differential cross sections for beauty and charm production were measured and compared with next-to-leading-order QCD calculations and Monte Carlo models., Published by Soc., [S.l.]

The $e^+$ -jet invariant mass spectrum produced in the reaction $e^+ p \rightarrow e^+ X$ has been studied at a center-of-mass energy of 300 GeV. The data were collected using the ZEUS detector operating at the HERA collider, and correspond to an integrated luminosity of $47.7$ pb $^{-1}$ . The observed mass spectrum is in good agreement with Standard Model expectations up to an $e^+$ -jet mass of $210$ GeV. Above this mass, some excess is seen. The angular distribution of these events is typical of high- $Q^2$ neutral current events and does not give convincing evidence for the presence of a narrow scalar or vector state. Limits are presented on the product of cross section and branching ratio for such a state and are interpreted as limits on leptoquark or R-parity-violating squark production. Specific leptoquark types are ruled out at 95% confidence level for coupling strength $\lambda=0.3$ for masses between 150 and 280 GeV.
