Neutral-current four-fermion production in e+e- interactions at 130 GeV ≤ √s ≤ 172 GeV: L3 Collaboration
, Physics Letters Section B Nuclear Elementary Particle and High Energy Physics, Vol: 413, Pages: 191-200, ISSN: 0370-2693A study of neutral-current four-fermion processes is performed, using data collected by the L3 detector at LEP during high-energy runs at centre-of-mass energies 130-136, 161 and 170-172 GeV, with integrated luminosities of 4.9, 10.7 and 10.1 pb<sup>-1</sup>, respectively. The total cross sections for the final states ℓℓℓ'ℓ' and ℓℓqq (ℓ, ℓ' = e, μ or τ) are measured and found to be in agreement with the Standard Model prediction. © 1997 Elsevier Science B.V.

Upsilon production in Z decays: L3 collaboration
, Physics Letters Section B Nuclear Elementary Particle and High Energy Physics, Vol: 413, Pages: 167-175, ISSN: 0370-2693We have searched for evidence of T production in 3.5 million hadronic Z decays collected by the L3 detector at LEP in 1991-1995. No signals are observed for the decay chain Z → ΥX; T → ℓ<sup>+</sup>ℓ<sup>-</sup> (ℓ= e,μ), therefore upper limits at the 95% confidence level are set on the following Z branching fractions: Br(Z → Υ(1S)X) < 5.5 × 10<sup>-5</sup>; Br(Z → Υ(2S)X) < 13.9 × 10<sup>-5</sup>; Br(Z → Υ(3S)X) < 9.4 × 10<sup>-5</sup>.

Hard-photon production at √s = 161 and 172 GeV at LEP L3 collaboration
, Physics Letters Section B Nuclear Elementary Particle and High Energy Physics, Vol: 413, Pages: 159-166, ISSN: 0370-2693We have studied the process e<sup>+</sup>e<sup>-</sup> → nγ (n ≥ 2) at centre-of-mass energies of 161.3 GeV and 172.1 GeV. The analysis is based on a sample of events collected by the L3 detector in 1996 corresponding to total integrated luminosities of 10.7 pb<sup>-1</sup> and 10.1 pb<sup>-1</sup> respectively. The observed rates of events with two and more photons and the characteristic distributions are in good agreement with the Standard Model expectations. This is used to set lower limits on contact interaction energy scale parameters, on the QED cut-off parameters and on the mass of excited electrons. © 1997 Elsevier Science B.V.

Search for heavy neutral and charged leptons in e+e- annihilation at √s = 161 and √s = 172 GeV
, Physics Letters Section B Nuclear Elementary Particle and High Energy Physics, Vol: 412, Pages: 189-200, ISSN: 0370-2693A search for unstable neutral and charged heavy leptons as well as for stable charged heavy leptons has been made at center-of-mass energies √s = 161 GeV and √s = 172 GeV with the L3 detector at LEP. No evidence for their existence was found. We exclude unstable neutral leptons of Dirac (Majorana) type for masses below 78.0 (66.7), 78.0 (66.7) and 72.2 (58.2) GeV, if the heavy neutrino couples to the electron, muon or tau family, respectively. We exclude unstable charged heavy leptons for masses below 81.0 GeV for a wide mass range of the associated neutral heavy lepton. The production of stable charged heavy leptons with a mass less than 84.2 GeV is also excluded. If the unstable charged heavy lepton decays via mixing into a massless neutrino, we exclude masses below 78.7 GeV. © 1997 Elsevier Science B.V.

Study of photon dissociation in diffractive photoproduction at HERA
, Zeitschrift für Physik C Particles and Fields, Vol: 75, Pages: 421-435, ISSN: 0170-9739Diffractive dissociation of quasi–real photons at a photon–proton centre of mass energy ofW ≈ 200 GeV is studied with the ZEUS detector at HERA. The process under considerationis γp → XN, where X is the diffractively dissociated photon system of mass MX and N iseither a proton or a nucleonic system with mass MN < 2 GeV. The cross section for this processin the interval 3 < MX < 24 GeV relative to the total photoproduction cross section wasmeasured to be σpartialD /σtot = 6.2 ± 0.2(stat) ± 1.4(syst)%. After extrapolating this result tothe mass interval of m2φ < M2X < 0.05W2 and correcting it for proton dissociation, the fractionof the total cross section attributed to single diffractive photon dissociation, γp → Xp, is foundto be σSD/σtot = 13.3 ± 0.5(stat) ± 3.6(syst)%. The mass spectrum of the dissociated photonsystem in the interval 8 < MX < 24 GeV can be described by the triple pomeron (IP IP IP)diagram with an effective pomeron intercept of αIP (0) = 1.12 ± 0.04(stat) ± 0.08(syst). Thecross section for photon dissociation in the range 3 < MX < 8 GeV is significantly higher thanthat expected from the triple pomeron amplitude describing the region 8 < MX < 24 GeV.Assuming that this discrepancy is due to a pomeron–pomeron–reggeon (IP IP IR) term, its contributionto the diffractive cross section in the interval 3 < MX < 24 GeV is estimated to befIP IP IR = 26 ± 3(stat) ± 12(syst)%.
