MEASUREMENT OF THE muon-neutrino CHARGED CURRENT CROSS-SECTION

Baker, N.J. ; Connolly, P.L. ; Kahn, S.A. ; et al.

The Fermilab 15-ft bubble chamber, filled with a heavy neon-hydrogen mix, was exposed to a narrow-band νμ beam. Based on the observation of 830 charged-current νμ interactions, the cross section was found consistent with a linear rise with the neutrino energy in the interval 10 GeV<~Eν≲240 GeV. The average slope was determined to be σνEν=(0.62±0.05)×10−38 cm2 GeV−1.

STRUCTURE OBSERVED IN THE SPIN SPIN CORRELATION PARAMETER C(LL) = (L, L, 0, 0) IN P P ELASTIC SCATTERING AROUND THETA (C.M.) = 90-DEGREES IN THE REGION P(LAB) = 2.5-GEV/C - 5.0-GEV/C

Inspire Record 180637 DOI 10.17182/hepdata.20626

The spin-spin correlation parameter CLL=(L, L; 0, 0) has been measured for p−p elastic scattering around θc.m.=90° up to plab=5 GeV/c. An interesting energy dependence is observed in CLL and the results are interpreted by comparison with other available data.

DIRECT MEASUREMENT OF THE GAMMA AND CHARGE MULTIPLICITIES IN ANTI-P P ANNIHILATIONS AT REST

Kalogeropoulos, T.E. ; Onengut, G. ; Petridou, C. ; et al.
Phys.Rev.D 26 (1982) 543-549, 1982.
Inspire Record 182184 DOI 10.17182/hepdata.49298

The γ-to-charge multiplicity ratio 〈Mγ〉〈Mch〉 in N¯N annihilations is restricted by I-spin conservation. In deuterium, the ratio is constrained by I-spin conservation to be equal to 1, while an experiment reported a value of 1.24±0.03; this measurement was based on missing and γ energies. The experiment reported in this paper measures the rate of conversion of γ's as a function of converter thickness and obtains 〈Mγ〉〈Mch〉=1.26±0.03 for p¯p annihilations, which is in agreement with the large γ excess observed in deuterium. Statistical models which ignore I-spin conservation predict such a γ excess, while those taking into account I-spin conservation predict values near 1.

RADIATIVE WIDTH OF THE K*+ (1430).

The FERMILAB-MINNESOTA-ROCHESTER collaboration Cihangir, S. ; Berg, D. ; Biel, J. ; et al.
Phys.Lett.B 117 (1982) 123-125, 1982.
Inspire Record 184277 DOI 10.17182/hepdata.30878

Using the Primakoff formalism, we have extracted the radiative decay width of the K ∗+ (1430) produced in coherent interactions of 200 GeV/ c K + mesons in nuclear targets. The width obtained is 240 ± 45 keV, a value reasonably consistent with quark-model predictions.

Experimental Study of Single Particle Inclusive Hadron Scattering and Associated Multiplicities

Brenner, A.E. ; Carey, David C. ; Elias, J.E. ; et al.
Phys.Rev.D 26 (1982) 1497, 1982.
Inspire Record 169446 DOI 10.17182/hepdata.4112

An experiment using the Fermilab Single Arm Spectrometer (SAS) facility and an associated nonmagnetic vertex detector studied the reactions a+p→c+X, where a and c were π±, K±, p, or p¯. Extensive measurements were made at 100 and 175 GeV/c beam momenta with the outgoing hadrons detected in the SAS covering a kinematic range 0.12<x<1.0 and pT<1.25 GeV/c. Additional data covering a more restricted range in x were also gathered at 70 GeV/c incident momentum. In this high-statistics experiment, the identification of both the incoming and outgoing charged hadrons were made with a total of eight Čerenkov counters. New and extensive single-particle inclusive data for charged-particle production in low-pT hadronic fragmentation are presented. The average associated charged-particle multiplicity and pseudorapidity distributions are also given.

Total Cross-sections for $\nu_\mu$ and $\bar{\nu}_\mu$ Charged Current Interactions Between 20-{GeV} and 200-{GeV}

The Aachen-Bonn-CERN-Democritos-London-Oxford-Saclay collaboration Bosetti, P. ; Deden, H. ; Fritze, P. ; et al.
Phys.Lett.B 110 (1982) 167-172, 1982.
Inspire Record 169123 DOI 10.17182/hepdata.30976

Exposures of the Ne/H 2 filled Big European Bubble Chamber (BEBC) to a dichromatic neutrino (antineutrino) beam produced by 400 GeV protons of the CERN SPS yielded ∼ 3100 events with a negative, and ∼ 1100 with a positive, muon. The neutrino flux is determined from the muon flux in the shielding. Assuming a linear energy dependence of the cross section, the values σ E between 20 and 200 GeV are found to be 0.657 ± 0.012 (stat.) ± 0.027 (syst.) and 0.309 ± 0.009 (stat.) ± 0.013 (syst.) cm 2 (GeV nucleon) −1 , for neutrinos and antineutrinos, respectively. The scaling variable q 2 E decreases significantly with increasing energy both for neutrinos and antineutrinos.

Search for $D^*$- Production With a 16-{GeV}/$c \pi^-$ Beam

Phys.Rev.Lett. 48 (1982) 785, 1982.
Inspire Record 170568 DOI 10.17182/hepdata.20594

A search for production of D*−'s using the decay chain D0π−, D0→K+π−, was carried out at the Brookhaven National Laboratory multiparticle spectrometer with a 16-GeV/c π− beam and a hydrogen target. At 95% confidence level the upper limits for the product of peripheral production cross section by branching ratio are 2.4 nb for inclusive D*− production and 1.3 nb for the exclusive channel π−p→D*−Λc.

Low Mass Electron Pair Anomaly in 17-{GeV}/c $\pi^- P$ Collisions

Stekas, J. ; Abshire, G. ; Adams, M.R. ; et al.
Phys.Rev.Lett. 47 (1981) 1686-1689, 1981.
Inspire Record 172147 DOI 10.17182/hepdata.20624

Inclusive e+e− production in 17-GeV/c π−p collisions has been measured. An excess of e+e− pairs over those from known sources for 0.1<~mee<~0.6 GeV and x<0.5 was found. No evidence is found for enhancements in specific final states involving electrons and photons or charged particles. The photon multiplicity associated with these pairs is measured.

Phys.Rev.D 26 (1982) 991, 1982.
Inspire Record 170499 DOI 10.17182/hepdata.38162

We present results on the jet structure observed in multihadronic events produced by e+e− annihilation in the Mark I magnetic detector at SPEAR. The evidence for jet structure and the jet-axis angular distribution are reported. We give inclusive distributions of the hadrons in Feynman x, rapidity, and transverse momentum relative to the jet axis.
