Abstract

Calorimeters have been used extensively for the study of neutrino interactions in the last decade. This paper describes the need for calibration of such calorimeters and how this was realized for the case of the CHARM fine-grained calorimeter. The energy and spatial response of the calorimeter to both hadronic and electromagnetic showers was measured in π and electron beams from 5 to 140 GeV. The results and resolutions are presented.

On the use of neural networks in high-energy physics experiments
1990, Computer Physics Communications
We investigate the possibilities for applying neural networks in high-energy physics experiments. After a survey of the main “intelligent behavior paradigms”, we discuss a number of possibilities where this new technology finds its application in particle detectors and particle accelerators. Finally, we comment on commercially available NN-tools, point to their limitations and extrapolate into the future.
Evidence for neutral neutrino current coupling to right-handed quarks
1989, Physics Letters B
Differential cross sections dσ/dy have been measured in semileptonic neutral- and charged-current reactions induced by neutrinos and antineutrinos. The comparison of the neutral- and the charged-current differential cross sections allows the direct determination of the chiral coupling of the neutral ( $v v$ ) current to left- and right-handed quarks. The result, with a value of g_R² = 0.042±0.010, is the first direct determination, with a significance of more than four standard deviations, of a non-zero value of g_R.
A detector for the study of neutrino-electron scattering
1989, Nuclear Inst. and Methods in Physics Research, A
The CHARM II Collaboration has built a massive, fine-grained and low-density detector for the study of muon-neutrino and muon-antineutrino scattering on electrons. The detector consists of a target calorimeter of 692 t of glass followed by a magnetic spectrometer. The calorimeter is used to detect the different types of neutrino interactions, and to measure the energy and direction of the produced particle showers; the spectrometer permits the determination of the momentum of muons produced in charged-current reactions on nuclei. The calorimeter is composed of 441 detector planes having a total of 154 560 plastic streamer tubes with digital readout of the wires and of 73920 cathode pickup strips grouped in 9240 channels with analog readout. It is further instrumented with 1540 scintillators. A complete description of the detector and some results of its performance with cosmic-ray muons are presented.
Experimental study of x-distributions in semileptonic neutral-current neutrino and antineutrino reactions
1988, Physics Letters B
Using the CHARM detector 36 000 deep inelastic neutral-current reactions of neutrinos (and 2000 of antineutrinos) from the 160 GeV narrow-band beam were recorded. The differential cross section $d σ d x$ in the Bjorken scaling variable x was computed by unfolding the effects of limited acceptance and of resolution of the detector as well as the ambiguity of the energy of the incoming neutrinos (produced by π- or K-decay). Combining the results from the neutrino and antineutrino data, the structure functions F₂ and xF₃ and the antiquark momentum distribution measured via the NC coupling were determined. The distributions are in agreement with the corresponding CC distibutions. Comparisons with deep inelastic muon scattering confirm the universality of nuclear structure functions as probed by the weak and the electromagnetic currents.
