Journal articleAcciarri M, Adriani O, Aguilar-Benitez M, et al., 1998,
Single and multi-photon events with missing energy in e<sup>+</sup>e<sup>-</sup> collisions at √s = 183 GeV
, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, Vol: 444, Pages: 503-515, ISSN: 0370-2693An analysis of single and multi-photon events with missing energy is performed using data collected with the L3 detector at LEP at centre-of-mass energies around 183 GeV, for a total of 55.3 pb-1 of integrated luminosity. The results obtained are in good agreement with the Standard Model prediction and are used to derive the value for the e+ e- →ννγ(γ) cross section as well as upper limits on cross sections of new physics processes. Several interpretations in supersymmetric models providing new limits on the masses of the lightest neutralino and of the gravitino are presented. © 1998 Elsevier Science B.V. All rights reserved.

Journal articleHori M, Torii HA, Hayano RS, et al., 1998,
Laser spectroscopic studies of state-dependent collisional quenching of the lifetimes of metastable antiprotonic helium atoms
, Physical Review A - Atomic, Molecular, and Optical Physics, Vol: 58, Pages: 1613-1627, ISSN: 1050-2947A laser spectroscopic method was developed to directly observe the lifetimes of individual states in metastable antiprotonic helium atoms (p̄ 4He+). Collisional effects with surrounding helium atoms were studied in cryogenic gas targets at pressures between 0.1 and 9.0 bars and at temperatures between 5.5 and 7.0 K. The metastable state (n, l) = (39,35) showed a lifetime of 1.5 μs, regardless of density, whereas the lifetime of the energetically lower-lying state (37,34) was found to shorten from 1.3 to 0.1 μs with increasing density. The lifetimes of the states (38,34) and (36,33) were determined to be 10 ns and 5 ns, respectively, showing the effects of the internal Auger process. When extrapolated to zero density, the measured lifetimes agreed with the results of calculations for the radiative and Auger widths. Using the fact that the state (37,34) becomes short lived at high density, the resonance (38,35)→(37,34) at a wavelength of 529.62 nm was detected.

Values for |Vcs| were extracted both from the measured hadronic branching ratio of W± decays and by tagging the flavour of hadronic jets produced in W± decays. Applying the two methods to the data collected during 1996 at energies of 161 and 172 GeV, DELPHI obtains |Vcs| = 0.091+0.15-0.14(stat) ± 0.05(syst). © 1998 Elsevier Science B.V. All rights reserved.
