The reaction e+e- → γγ(γ) at Z0 energies
, Physics Letters B, Vol: 268, Pages: 296-304, ISSN: 0370-2693The total and differential cross-sections for the reaction e<sup>+</sup>e<sup>-</sup> → γγ(γ) are measured at centre of mass energies around 91 GeV using an integrated luminosity of 4.7 pb<sup>-1</sup>. The aggreement with QED prediction is good. Consequently there is no evidence for non-standard channels which would have the same experimental signature. The lower limits on the QED cuttoff parameters are Λ<inf>+</inf> > 113 GeV and Λ<inf>-</inf> > 95 GeV. An upper limit on the effective coupling between a possible excited electron and the gamma is derived. At 95% confidence level the branching ratios for Z<sup>0</sup> decay into π<sup>0</sup>γ, ηψ and γγγ are below 1.5 × 10<sup>-4</sup>, 2.8 × 10<sup>-4</sup> and 1.4 × 10<sup>-4</sup> respectively. © 1991.

Performance of a uranium/tetramethylpentane calorimeter backed by an iron/scintillator calorimeter
, Nuclear Inst and Methods in Physics Research A, Vol: 305, Pages: 331-343, ISSN: 0168-9002We present results from the barrel depleted uranium/TMP calorimeter modules constructed by the UA1 Collaboration. Electromagnetic and hadronic energy resolutions have been measured using electron and pion beams with momenta in the range 7 to 70 GeV/c. Results on the energy linearity and the spatial uniformity of response are reported. The electromagnetic shower position resolution has been measured as a function of energy using a fine grained position detector placed at a depth of - 3.5χ<inf>0</inf>. The noise arising both from the electronics chain and from the uranium radioactivity is compared with 70 GeV/c muon signals. The ratio of the electron to pion response has been measured both as a function of the energy and of the electric field. The high lateral and longitudinal granularity of the calorimeter and the presence of a position detector have been used to determine the electron pion separation as a function of energy. © 1991.

Separation of minimum and higher twist in photoproduction of high-PT mesons
, Zeitschrift Fur Physik C Particles and Fields, Vol: 50, Pages: 179-184, ISSN: 0170-9739Photo- and hadroproduction data in the beam energy range 65-175 GeV have been studied with a view to isolating higher-twist processes in photoproduction from other point-like and hadron-like contributions. With selection of charged tracks having p<inf>T</inf>>2 GeV/c and 0.28<x<inf>F</inf><0.84 indications of a higher twist contribution have been found at a level that is consistent with QCD expectations. © 1991 Springer-Verlag.

, Zeitschrift Fur Physik C Particles and Fields, Vol: 50, Pages: 11-20, ISSN: 0170-9739Properties of D mesons produced in the photo-production experiment NA 14/2 at CERN are reported.

The angular distributions of D<sup>0</sup>→ {Mathematical expression}<sup>*0</sup> showed parity violation and destructive interference between S- and D-waves.
