Anti-proton - Helium Annihilation Around 44-{MeV}/$c$

Balestra, F. ; Bossolasco, S. ; Bussa, M.P. ; et al.
Phys.Lett.B 230 (1989) 36-40, 1989.
Inspire Record 276657 DOI 10.17182/hepdata.49625

The p¯4He annihilation cross section averaged over the interval 40–50 MeV/ c has been measured using a streamer chamber in a magnetic field. The measured value is 1342±250 mb. It agrees with a behaviour like 1/ p of the annihilation cross section. Our result has been obtained at the lowest momentum achieved till now in measurements of antiproton annihilation in flight.

Difference of nonannihilation anti-p p interactions at 22.4-GeV/c from p p interactions at close energy

Batyunya, B.V. ;
JINR-1-89-28, 1989.
Inspire Record 292242 DOI 10.17182/hepdata.54979

The longitudinal and transverse momentum distributions of protons and π±-mesons, produced and pp interactions at close energy (22-24 GeV), are compared. The existence of a difference between these (P<1.2 GeV/c in laboratory system) and for mesons accompaying them, is shown. The observed difference increases with increasing the multiplicity of charged particles. For π+ mesons it increases with decreasing the momentum of accompaying protons. These effects do not practically exist for π- mesons

Experimental Study of Muon Pairs Produced by 252-GeV Pions on Tungsten

The E615 collaboration Conway, J.S. ; Adolphsen, C.E. ; Alexander, J.P. ; et al.
Phys.Rev.D 39 (1989) 92-122, 1989.
Inspire Record 280845 DOI 10.17182/hepdata.23151

We present the results of a study of muon pairs with invariant masses greater than 4.05 GeV/c2 produced in high-energy pion-nucleon interactions. The production cross section together with the inferred pion and nucleon structure functions are reported and compared with other experiments and with QCD predictions. The transverse-momentum distributions are also presented. Finally, the full angular distribution in cosθ and φ is given as a function of mass, Feynman x, and transverse momentum. Longitudinal photon polarization is seen in the lower portion of the mass range at high xπ. This result is compared with a higher-twist model.
