Journal articleAskebjer P, Barwick SW, Bergström L, et al., 1997,
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.

A signal is observed in the invariant mass distribution M(γD<sup>-</sup> <inf>s</inf>) corresponding to the decay sequence D<sup>*-</sup> <inf>s</inf> → γD<sup>-</sup> <inf>s</inf>, D<sup>-</sup> <inf>s</inf> → τ<sup>-</sup>v̄<inf>τ</inf>, τ<sup>-</sup> → l<sup>-</sup>v̄<inf>l</inf>v<inf>τ</inf>.

No signal of B<sup>-</sup> → τ<sup>-</sup>v̄<inf>τ</inf> decays is observed in the data, corresponding to an upper limit on the branching fraction B (B<sup>-</sup> → τ<sup>-</sup>v̄<inf>τ</inf>) < 5.7 × 10<sup>-4</sup> at 90% CL. © 1997 Elsevier Science B.V.
