The (3 $\pi$) - Nucleon Collision in Coherent Production on Nuclei at 40-{GeV}/$c$

Bellini, G. ; Chernenko, L.P. ; Datsko, V.S. ; et al.
Nucl.Phys.B 199 (1982) 1-26, 1982.
Inspire Record 165248 DOI 10.17182/hepdata.49659

Coherent 3 π production on nine different nuclear targets has been studied using a 40 GeV/ c π − beam at the Serpukhov accelerator (CERN-Serpukhov experiment no. 5). The absorption in nuclear matter of the produced system has been measured, analysing the data on the different nuclear targets. Identica results are obtained from the differential cross sections and from the coherent nuclear cross sections. The 1 + waves show a very weak absorption, definitely smaller than 0 − and 2 − waves. No influence on the absorption comes from the spin-flip amplitudes, which have been found to be negligible in the coherent region.

Study of gluon versus quark fragmentation in Upsilon --> g g gamma and e+ e- --> q anti-q gamma events at s**(1/2) = 10-GeV.

The CLEO collaboration Alam, M.S. ; Athar, S.B. ; Ling, Z. ; et al.

Inspire Record 439530 DOI 10.17182/hepdata.47233

Using data collected with the CLEO II detector at the Cornell Electron Storage Ring, we determine the ratio R(chrg) for the mean charged multiplicity observed in Upsilon(1S)->gggamma events, to the mean charged multiplicity observed in e+e- -> qqbar gamma events. We find R(chrg)=1.04+/-0.02+/-0.05 for jet-jet masses less than 7 GeV.

Measurement of the form-factor ratios for D/s+ --> Phi l+ nu/l.

The E791 collaboration Aitala, E.M. ; Amato, S. ; Anjos, J.C. ; et al.
Phys.Lett.B 450 (1999) 294-300, 1999.
Inspire Record 480733 DOI 10.17182/hepdata.42137

We have measured the form factor ratios r_V = V(0)/A_1(0) and r_2 = A_2(0)/A_1(0) for the decay D_s^+ -> phi ell^+ nu_ell, phi -> K^+ K^-, using data from charm hadroproduction experiment E791 at Fermilab. Results are based on 144 signal and 22 background events in the electron channel and 127 signal and 34 background events in the muon channel. We combine the measurements from both lepton channels to obtain r_V = 2.27 +- 0.35 +- 0.22 and r_2 = 1.57 +- 0.25 +- 0.19.

A MEASUREMENT OF pi+ p BACKWARD ELASTIC DIFFERENTIAL CROSS-SECTIONS FROM 1.282-GeV/c TO 2.472-GeV/c

Candlin, D.J. ; Lowe, D.C. ; Peach, K.J. ; et al.
Nucl.Phys.B 244 (1984) 23-56, 1984.
Inspire Record 201771 DOI 10.17182/hepdata.7101

New high-statistics measurements of π + p elastic scattering differential cross sections are presented at 30 momentum points between 1.282 and 2.472 GeV/ c , covering most of the angular distribution outside the forward diffractive peak. These data show significant disagreements at some momenta with previous high-statistics experiments and with current partial wave analyses.
