Quark fragmentation functions are studied with ≈3500 charged current events induced in the bubble chamber Gargamelle by neutrinos of the SPS wide band beam, with 〈Eν〉 ≈ 25 GeV. The Q2 and W2 regions covered by this experiment are Q2 ≈ 0–40 GeV2 and W2 ≈ 1–100 GeV2, the mean values being 〈Q2〉 = 6.5 GeV2, 〈W2〉 = 22GeV2. A correlation between the variables and is found in the data in the region Q2 = 1–10 GeV2, which can be explained in terms of higher twist effects. These effects reproduce the Q2 evolution of the non-singlet moments of the fragmentation function without any need for logarithmic terms. 相似文献

New results are presented of an analysis of pictures taken during an exposure of Gargamelle to the CERN ν beam in 1975. In addition to three νμ+N→μ?+e++V0+ hadrons events previously reported, an excess is found of events of the type νμ+N→μ?+e++ hadrons without V0. An analysis of strange particle production in charged current events suggests a possible violation of the ΔS=ΔQ rule. Interpreted in terms of charm production, the data permit an estimate of branching ratios and production rate of charmed particles. A limit is also placed on charmed particle production by neutral currents. 相似文献

A sample of 357 events fitting the reaction ν + p → μ? + p + π+ on free proton is obtained from the Gargamelle neutrino propane experiment at the CERN-PS. The average value of the cross section above 1 GeV is found to be (0.60 ± 0.07) 10?38 cm2. The reaction is dominated by the production of the Δ++(1232) resonance. Results on the Δ++ spin density matrix are given. 相似文献

Summary PFS is a two-channel Fourier spectrometer operating in the infra-red wavelengths between 1.25 and 45 μm. The instrument will
be used mainly in the study of the Martian atmosphere. The principal goals are the measurements of the atmospheric temperature
and pressure, atmospheric constituents, aerosol and clouds, ground pressure for surface topography, optical and thermophysics
properties of the Martian soil. PFS will fly on the Mars 94 spacecraft which should be launched in 1994 and reach the planet
in 1995. It is essentially constituted by two different interferometers located in the same box which is divided into two
parts. A dichroic placed on the PFS entrance is used to separate the spectral range into two parts, a division needed by the
different optical materials which have to be used in each spectral range. The optical layout of the experiment is very compact.
Each channel uses two cubic mirrors mounted on an L-structure pivoted on a motor. The motor moves the mechanics and permits
the optical-path difference between the arms to be varied. Each interformeter operates in a different spectral range, respectively,
between (1.25÷4.8) μm (8000÷2083cm−1) and (6÷45)μm (1666÷220)cm−1). The spectral resolution is 2 cm−1. The entrance aperture area is 30 cm2 per channel and the field of view is 2 and 4 degrees. Every measurement lasts about 4 s. The time and, therefore, the relative
optical-path difference for the measurement of every point of the interferogram is given by the zero crossings of the interferogram
of a reference monochromatic channel at 1.2 μm which uses a laser diode as source. The two interferograms are double-sided
and will have 16384 and 4096 points, respectively, corresponding to spectra of 6250 and 1823 useful points.
