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.

COMPTON EFFECT ON pi- MESON

Antipov, Yu.M. ; Batarin, V.A. ; Bessubov, V.A. ; et al.
Z.Phys.C 24 (1984) 39, 1984.
Inspire Record 193860 DOI 10.17182/hepdata.41183

The reaction π−A→Aπ− γ at 40 GeV/c was studied on “Sigma” spectrometer on six different nuclear targets in the region of four-momentum transfer |t|<0.05 (GeV/c)2. A phenomenon of elastic scattering of pions on the nuclear Coulomb field photons was observed, its total and differential cross sections were measured. The cross section of Compton effect on π−-meson was measured.

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.
