A Study of the Proton Momentum Spectrum From Deuteron Fragmentation at 8.9 GeV/$c$ and an Estimate of Admixture Parameters for the Six Quark State in Deuteron

The momentum spectrum of protons emitted at small angles in the stripping reaction d + 12 C → p + X has been measured at a deuteron momentum of 8.9 GeV/ c . The data are described in the framework of the Glauber-Sitenko theory using the hybrid model of the deuteron wave function which includes a six-quark state. The parameters of this state are determined. A shoulder in the spectrum has been observed in the proton momenta region which kinematically corresponds to the production of a dibaryon resonance with a mass from 2.0 to 2.2 GeV.

Measurement of Production Properties of Positively Charged Kaons in Proton-Carbon Interactions at 31 GeV/c

The NA61/SHINE collaboration Abgrall, N. ; Aduszkiewicz, A. ; Anticic, T. ; et al.
Phys.Rev.C 85 (2012) 035210, 2012.
Inspire Record 1079585 DOI 10.17182/hepdata.59717

Spectra of positively charged kaons in p+C interactions at 31 GeV/c were measured with the NA61/SHINE spectrometer at the CERN SPS. The analysis is based on the full set of data collected in 2007 with a graphite target with a thickness of 4% of a nuclear interaction length. Interaction cross sections and charged pion spectra were already measured using the same set of data. These new measurements in combination with the published ones are required to improve predictions of the neutrino flux for the T2K long baseline neutrino oscillation experiment in Japan. In particular, the knowledge of kaon production is crucial for precisely predicting the intrinsic electron neutrino component and the high energy tail of the T2K beam. The results are presented as a function of laboratory momentum in 2 intervals of the laboratory polar angle covering the range from 20 up to 240 mrad. The kaon spectra are compared with predictions of several hadron production models. Using the published pion results and the new kaon data, the K+/\pi+ ratios are computed.

Search for the dark photon in $\pi^0$ decays

The NA48/2 collaboration Batley, J.R. ; Kalmus, G. ; Lazzeroni, C. ; et al.
Phys.Lett.B 746 (2015) 178-185, 2015.
Inspire Record 1357601 DOI 10.17182/hepdata.67658

A sample of $1.69\times 10^7$ fully reconstructed $\pi^0\to\gamma e^+e^-$ decay candidates collected by the NA48/2 experiment at CERN in 2003--2004 is analysed to search for the dark photon ($A'$) production in the $\pi^0\to\gamma A'$ decay followed by the prompt $A'\to e^+e^-$ decay. No signal is observed, and an exclusion region in the plane of the dark photon mass $m_{A'}$ and mixing parameter $\varepsilon^2$ is established. The obtained upper limits on $\varepsilon^2$ are more stringent than the previous limits in the mass range $9~{\rm MeV}/c^2<m_{A'}<70~{\rm MeV}/c^2$. The NA48/2 sensitivity to the dark photon production in the $K^\pm\to\pi^\pm A'$ decay is also evaluated.
