Electroproduction of Neutral Pions at Energies Above the Resonance Region

Brasse, F.W. ; Fehrenbach, W. ; Flauger, W. ; et al.
Phys.Lett.B 58 (1975) 467, 1975.
Inspire Record 99604 DOI 10.17182/hepdata.27793

The reaction e p→e'p π 0 has been measured at W =2.55 GeV a fixed electron scattering angle of 10.3°. Two magnetic spectrometers and a lead glass hodoscope were used to detect all four final state particles. Electroproduction cross sections in the t range −0.15 to −1.4 (GeV/ c ) 2 at q 2 = −0.22, −0.55 and −0.85 (GeV/ c ) 2 are presented. Above | t |=0.6 (GeV/ c ) 2 the cross sections are considerably smaller than those for photoproduction.

Production and decay of sigma(1660)

Apsell, S.P. ; Ford, P. ; Gourevitch, S. ; et al.
Phys.Rev.D 10 (1974) 1419-1429, 1974.
Inspire Record 95499 DOI 10.17182/hepdata.25064

An investigation has been performed of some properties of Σ(1660) produced in the reaction K−p→Σ+(1660)π− at 2.87 GeV/c incident K− momentum. The decay modes observed for this state include Λ(1405)π and Σπ. The spin and parity are measured to be JP=32−. The differential cross section of the Λ(1405)π decay mode is sharply peaked in the forward direction, falling exponentially with a slope of 5.6 ± 0.7 (GeV/c)−2, while the slope for the Σ0π+ decay mode is 2.1 ± 0.4 (GeV/c)−2. The difference in the ratio of backward to total events for the two decay modes also suggests that two Σ(1660)'s exist.

On helicity conservation in the reaction pi- p ---> a1 p at 4.45 gev/c

Beketov, G.V. ; Zombkovsky, S.M. ; Kaidalov, A.B. ; et al.
Nucl.Phys.B 59 (1973) 265-272, 1973.
Inspire Record 83967 DOI 10.17182/hepdata.32538

Helicity conservation in the reaction π − p → pA 1 at 4.45 GeV/ c has been studied using 50 cm and 55 cm liquid hydrogen bubble chambers. In the Jackson and the helicity frames the dependence of the ϱ matrix elements on the four-momentum transfer squared to the proton ( t ) for A 1 maximum decay has been calculated. The obtained data are in a good agreement with t -channel helicity conservation. The t -channel dependence of the ϱ matrix elements in the mentioned frames is in good agreement with that calculated using the Regge π-pole exchange model (it is suggested that the A 1 maximum nature is explained by a kinematical effect of the Deck type).

Total cross sections for π − , K − and p on protons and deutrons have been measured in the momentum range 15 to 60 GeV/ c . Total cross sections for particle interactions with neutrons have been determined with an energy dependent Glauber correction. Using the positive particle data obtained earlier with the same experimental apparatus, the differences of total cross sections for particles and antiparticles as well as for particles belonging to the same isospin multiplet have been calculated.
