The cross section of the process e+ e- ---> eta gamma has been measured in the 600-1380 MeV c.m. energy range with the CMD-2 detector. The following branching ratios have been determined: B(rho ---> eta gamma) = (3.28 +- 0.37 +- 0.23) 10^{-4}, B(omega ---> eta gamma) = (5.10 +- 0.72 +- 0.34) 10^{-4}, B(phi --> eta gamma) = (1.287 +- 0.013 +- 0.063) 10^{-2}. Evidence for the rho'(1450) ---> eta gamma decay has been obtained for the first time.

Study of the radiative decay $\phi \to \eta \gamma$ with CMD-2 detector

The CMD-2 collaboration Akhmetshin, R.R. ; Anashkin, E.V. ; Banzarov, V.S. ; et al.
Phys.Lett.B 460 (1999) 242-247, 1999.
Inspire Record 503154 DOI 10.17182/hepdata.27081

Using the $1.9 pb^{-1}$ of data collected with the CMD-2 detector at VEPP-2M the decay mode $\phi \to \eta \gamma$, $\eta \to \pi^+\pi^-\pi^0$ has been studied. The obtained branching ratio is B($\phi \to \eta \gamma) = (1.18 \pm 0.03 \pm 0.06) %$.

Inclusive Negative Hadron Production from High Energy $\bar{\nu}$ Nucleus Charged Current Interactions

Berge, J.P. ; Bogert, D. ; Endorf, R. ; et al.
Phys.Rev.D 18 (1978) 3905, 1978.
Inspire Record 130082 DOI 10.17182/hepdata.24370

We present data on inclusive negative-hadron production from charged-current antineutrino interactions in a 21% Ne-H mixture. Inclusive single-particle distributions are presented and are shown to be insensitive to the momentum transferred to the hadron vertex. Comparisons made to inclusive data from π−p and π−n interactions indicate a close similarity between the hadrons resulting from π-nucleon and ν¯-nucleus interactions. The general features of the ν¯-nucleus data are found to be similar to those seen in ν¯p interactions. This last observation implies that ν¯p and ν¯n interactions are similar and that nuclear effects are small.

Measurement of the Interference Structure Function Xg(3) (X) in Muon - Nucleon Scattering

Argento, A. ; Benvenuti, A.C. ; Bollini, D. ; et al.
Phys.Lett.B 140 (1984) 142-144, 1984.
Inspire Record 195945 DOI 10.17182/hepdata.13025

The interference structure function xG 3 ( x ) has been measured for the first time scattering positive and negative muons of opposite helicity off a carbon target. The x dependence observed for Q 2 between 40 and 180 (GeV/c 2 ) is in good agreement with predictions of the quark-parton model. The measured ratio 2( a u Q u + a d Q d )/( Q u 2 + Q d 2 = 1.87 ± 0.25 (stat.) ± 0.24 (syst.) is consistent with the hypothesis of fractional quark charges and determines the sign of Q u − Q d to be positive.

Total cross-section of two photon production of hadrons

Baru, S.E. ; Beilin, M.V. ; Blinov, A.E. ; et al.
Z.Phys.C 53 (1992) 219-224, 1992.
Inspire Record 33675 DOI 10.17182/hepdata.14767

The total cross section for γγ→hadrons was measured as a function of the invariant massW of the system (1.25 to 4.25 GeV) at thee+e−-collider VEPP-4 with the detector MD-1. For the first time the data were obtained by detecting both scattered leptons with almost zero emission angles. The mean squared four momentum transfer 〈q2〉 is −0.005 GeV2, the rmsW resolution is 100–250 MeV. The data on the mean charged multiplicity 〈nC〉 are well described by the function 〈nC〉=(1.62 ±0.37)+(1.83±0.45)·ln(W(GeV)). TheW dependence of the total cross section is consistent with the theoretical prediction σ(nb)=240+270/W(GeV).
