QCD studies and determination of αs in e+e- collisions at √s = 161 GeV and 172 GeV L3 Collaboration
, Physics Letters Section B Nuclear Elementary Particle and High Energy Physics, Vol: 404, Pages: 390-402, ISSN: 0370-2693We present a study of the structure of hadronic events recorded by the L3 detector at LEP at the center of mass energies of 161 and 172 GeV. The data sample corresponds to an integrated luminosity of 21.25 pb<sup>-1</sup> collected during the high energy runs of 1996. The distributions of event shape variables and the energy dependence of their mean values are well reproduced by QCD models. From a comparison of the data with resummed script O sign (α<sup>2</sup> <inf>s</inf>) QCD calculations, we determine the strong coupling constant at the two energies. Combining this with our earlier measurements we find that the strong coupling constant decreases with increasing energy as expected in QCD. © 1997 Published by Elsevier Science B.V.

Absorption spectra of fiber light pipes made from pure quartz and irradiated by 60Co gamma quanta
, Pribory I Tekhnika Eksperimenta, Pages: 23-32, ISSN: 0032-8162The aim of the paper is to study the radiation resistance of quartz fiber light pipes as an active medium of a front calorimeter in future collider experiments. The absorption spectra of different types of quartz fiber light pipes in the wave length range from 200 to 700 nm, irradiated by gamma quanta at the integral dose from 10 to 1000 Mrad, are measured. It is established that there is the spectral range with minimum growth of optical losses when increasing the absorbed dose. It is found also that increasing the dose above 57 Mrad is accompanied by not only increase optical losses but and destruction of the polymer shell of a fiber light pipe.

Optical properties of deep ice at the South Pole: Absorption
, Applied Optics, Vol: 36, Pages: 4168-4180, ISSN: 1559-128XWe discuss recent measurements of the wavelength-dependent absorption coefficients in deep South Pole ice. The method uses transit-time distributions of pulses from a variable-frequency laser sent between emitters and receivers embedded in the ice. At depths of 800-1000 m scattering is dominated by residual air bubbles, whereas absorption occurs both in ice itself and in insoluble impurities. The absorption coefficient increases approximately exponentially with wavelength in the measured interval 410-610 nm. At the shortest wavelength our value is approximately a factor 20 below previous values obtained for laboratory ice and lake ice; with increasing wavelength the discrepancy with previous measurements decreases. At ˜415 to ˜500 nm the experimental uncertainties are small enough for us to resolve an extrinsic contribution to absorption in ice: Submicrometer dust particles contribute by an amount that increases with depth and corresponds well with the expected increase seen near the Last Glacial Maximum in Vostok and Dome C ice cores. The laser pulse method allows remote mapping of gross structure in dust concentration as a function of depth in glacial ice. © 1997 Optical Society of America.

Search for excited leptons in e+e- annihilation at √s = 161 GeV
, Physics Letters Section B Nuclear Elementary Particle and High Energy Physics, Vol: 401, Pages: 139-149, ISSN: 0370-2693A search for excited leptons e*, μ*, τ* and ν*<inf>e</inf> in e<sup>+</sup>e<sup>-</sup> collisions at √s = 161 GeV is performed using the 10.8 pb<sup>-1</sup> of data collected by the L3 detector at LEP. No evidence has been found for their existence. From an analysis of the expected ℓ*ℓ* pair production in the channels eeγγ, μμγγ, ττγγ, eeWW, and ννγγ, the lower mass limits at 95% C.L. are 79.7 GeV for e*, 79.9 GeV for μ*, 79.3 GeV for τ* and 71.2 GeV for ν*<inf>e</inf> assuming the same couplings as for standard leptons. From an analysis of the expected ℓℓ* single production in channels eeγ, μμγγ, τγγ, ν<inf>e</inf>eW and ννγ, the upper limits on the couplings λ/m<inf>ℓ*</inf> up to m<inf>ℓ*</inf> = 161 GeV are determined. © 1997 Published by Elsevier Science B.V.
