We have studied the reactions K+p→K0Δ++(1236) at 15.7 GeVc, K−p→K¯0n at 10.7 and 15.7 GeVc, and K−p→K¯0Δ0(1236) at 15.7 GeVc in the BNL Double Vee Magnetic Spectrometer. The π+ and π− from the decays of forward K0's were detected and the above reactions were identified by a missing-mass technique. Total and differential cross sections are presented for the first two reactions and a total cross section for the third.

Neutral associated production by 8, 10.7 and 15.7 gev/c pi- incident on protons

Foley, K.J. ; Love, W.A. ; Ozaki, S. ; et al.

Phys.Rev.D 8 (1973) 27-38, 1973.

Inspire Record 81979 DOI 10.17182/hepdata.22059

We present differential and total cross sections for two reactions: π−p→K0Λ and π−p→K0Σ0. The incident pion momenta were 8, 10.7, and 15.7 GeVc. The results are based on an analysis of approximately 22 600 events of the two reactions where the π+ and π− from the decay of the KS0 were detected in the forward leg of the Double Vee Magnetic Spectrometer. The separation of Λ recoils from Σ0 recoils was accomplished by the missing-mass technique.

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.

Increased Statistics and Observation of the $g(T$), $g(T$)-prime, and $g(T$)-prime-prime 2++ Resonances in the Glueball Enhanced Channel $\pi^- p \to \phi \phi n$

In a new experiment we have obtained 3006 new events in the reaction π − p → φφ n, approximately doubling the statistics which now total 6658. A refined partial wave analysis of the φφ system again reveals three resonances (g T , g T′ , g T′' ) with I G J PC =0 + 2 ++ . The absence of the OZI suppression, and the observation of only three J PC =2 ++ states (g T , g T′ , g T′' ) which comprise virtually all the cross section are unusual characteristics of the data. The large φφn signal occurs over a mostly structureless and incoherent φK + K − n background. All these unusual characteristics are well explained if these states are produced by 1–3 glueballs (multigluon resonances).

We present differential and total cross sections for the reactions π−p→K0[Σ(1385)Λ(1405)] and π−p→K0Λ(1520) at incident pion momenta of 8.0, 10.7, and 15.7 GeV/c. Pions from the decay of the forward K0s's were detected in the forward leg of the BNL double-vee spectrometer and the recoil Y* 's were identified by the missing-mass technique.

High Statistics Investigation of K0 K- Decay of a2- Produced by 23-GeV/c pi- on Hydrogen

We present the results of an experiment to study the reaction π−p→A2−p, A2−→KS0K− at 22.4 and 23.9 GeV/c. We have 3346 KS0K− events in the effective mass region 1.1 to 1.5 GeV, and covering the |t′| interval 0.0 to 1.0 (GeV/c)2. Because of the low background in this channel, we are able to study various |t′| regions, including the region 0.2 to 0.29 (GeV/c)2 in which the original split A2 peak was observed. We find no substructure in any region. We have also derived differential and total cross sections. The differential cross sections are well fitted by the form dσdt′=At′ebt′ with b≈7.0 (GeV/c)−2. The total cross section is in good agreement with the value derived from other experiments that measure the A2−→ρ0π− decay mode.

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

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.

Total Cross-Sections for Charged Current Neutrino and anti-neutrino Interactions in BEBC in the Energy Range 20-GeV to 200-GeV

Inspire Record 121301 DOI 10.17182/hepdata.27526

The charged-current cross sections for neutrinos and antineutrinos on nucleons in the energy range 20–200 GeV are given. Taken in conjunction with the previous Gargamelle results, they show that σ E is almost constant with energy for antineutrinos, and falls with energy for neutrinos. The value of 〈q 2 〉 E decreases with energy for both neutrinos and antineutrinos, and these deviations from exact Bjorken scaling are consistent with those observed in electron and muon inelastic scattering. We find no evidence for new heavy quark states with right-handed coupling.
