Study of A2- --> eta pi- in the Reaction pi- p --> pi- pi- pi+ pi0 p at 11.2-GeV/c

The analysis of A2−→ηπ− at 11.2 GeV/c confirms that A2− is essentially produced by natural-parity exchange. In the differential cross-section as a function oft′ there is evidence of the dip at smallt′ values. The branching ratio (A2→ηπ)/(A2→ϱπ) is 0.18±0.05.

A Study of the Reactions K0(L) p --> Lambda pi+, Lambda pi+ pi0 and Sigma0 pi+ in the Center-Of-Mass Energy Range 1490-MeV-1700-MeV

The Bologna-Edinburgh-Glasgow-Pisa-Rutherford collaboration Bertanza, L. ; Cameron, W. ; Capiluppi, P. ; et al.
Nucl.Phys.B 110 (1976) 1-24, 1976.

K L 0 p interactions were studied in the CERN 2m H 2 bubble chamber in the c.m. energy range 1490–1700 MeV. The experimental details are described. Results are presented on the final states Λπ + , Σ 0 π + and Λπ + π 0 . The effect of these data on a recent partial-wave analysis of the two-body states is examined.

Azimuthal Asymmetry in Inclusive Hadron Production by e+ e- Annihilation

Schwitters, R. ; Boyarski, A. ; Breidenbach, Martin ; et al.
Phys.Rev.Lett. 35 (1975) 1320, 1975.
Inspire Record 100683 DOI 10.17182/hepdata.21192

We have observed an azimuthal asymmetry in inclusive hadron production by e+e− annihilation at the center-of-mass energy s=7.4 GeV. The asymmetry is caused by the polarization of the circulating beams in the storage ring and allows separate determination of the transverse and longitudinal structure functions. We find that transverse production dominates for x>0.2 where x is the scaling variable 2ps.

A Study of the Hadronic Angular Distribution in (e+ e-) Processes from 1.2-GeV to 3.0-GeV

Bernardini, M. ; Bollini, D. ; Brunini, P.L. ; et al.
Nuovo Cim.A 26 (1975) 163, 1975.
Inspire Record 91111 DOI 10.17182/hepdata.37720

The angular distribution of 2720 tracks of 1085 hadronic final states produced from (e+e-) annihilation has been studied in the 1.2 to 3.0 GeV total centre-of-mass energy range. If we parametrize the angular distribution in terms off(θ) =1 + A cos2 θ, where 6 is the angle between the hadronic track produced and the colliding-beam direction, the results show thatA is less than 0.21, with 90% confidence.
