DECAY DISTRIBUTION OF HIGH TRANSVERSE MOMENTUM RHO MESONS

Heppelmann, S. ; Blazey, G.C. ; Baller, B. ; et al.
Phys.Rev.Lett. 55 (1985) 1824-1827, 1985.
Inspire Record 221964 DOI 10.17182/hepdata.20301

The exclusive process π−p→ρ−p has been measured at 90° c.m. with an incident pion momentum of 9.9 GeV/c. We present data on the angular dependence of the decay ρ−→π−π0. We observe a strong azimuthal dependence in the decay in the c.m. helicity frame of the ρ. Such an azimuthal dependence is not compatible with SU(6) valence-quark perturbation calculations.

Measurement of $\alpha \alpha$ and $\alpha p$ Elastic Scattering at the {CERN} {ISR}

Bell, W. ; Braune, K. ; Claesson, G. ; et al.
Phys.Lett.B 117 (1982) 131-134, 1982.
Inspire Record 177982 DOI 10.17182/hepdata.30868

Differential cross sections for αα and αp scattering have been measured at √ s =125 and 88 GeV, respectively, in the t range from −0.2 to −0.8 (GeV/ c ) 2 using the Split-Field Magnet detector at the CERN Intersecting Storage Rings. Comparison with theoretical calculations using the Glauber model confirms the importance of including inelastic shadowing effects in very high energy nucleus-nucleus elastic scattering.

The FERMILAB-MINNESOTA-ROCHESTER collaboration Cihangir, S. ; Berg, D. ; Biel, J. ; et al.
Phys.Lett.B 117 (1982) 119-122, 1982.
Inspire Record 182836 DOI 10.17182/hepdata.30869

Using the Primakoff formalism, we have extracted the radiative decay width of the A + 2 (1310) produced in coherent interactions of 200 GeV/ c π + mesons in nuclear targets. The width obtained is 295 ± 60 keV, a value consistent with quark-model predictions.

Inspire Record 184277 DOI 10.17182/hepdata.30878

Using the Primakoff formalism, we have extracted the radiative decay width of the K ∗+ (1430) produced in coherent interactions of 200 GeV/ c K + mesons in nuclear targets. The width obtained is 240 ± 45 keV, a value reasonably consistent with quark-model predictions.

Evidence for a New Pseudoscalar Meson

Bonesini, M. ; Donald, R.A. ; Edwards, D.N. ; et al.
Phys.Lett.B 103 (1981) 75-78, 1981.
Inspire Record 170357 DOI 10.17182/hepdata.31149

Performing a PWA of the π − π − π + system over the −t p/p range 0.2 to 0.4 GeV 2 we find evidence for a J P = 0 − , J G =1 − meson of mass 1342 ± 20 MeV and width 220 ±70 MeV decaying into ϵπ. This state is produced by natural parity exchange with a slope similar to that of elastic scattering. It can be interpreted as a radial excitation of the π meson (π′).

Exclusive Reactions in $\bar{p} p$ Interactions at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Jabiol, M.A. ; Denegri, D. ; Louedec, C. ; et al.
Nucl.Phys.B 183 (1981) 330-348, 1981.
Inspire Record 155103 DOI 10.17182/hepdata.34313

The cross sections of several exclusive reactions in p p interactions are given. In the channels p p → p p π + π − and p p → p p 2π + 2π − which dominate the interactions, the single and double diffractive dissociations are analysed and compared to the results obtained with K ± p interactions at the same energy, pp and p p interactions at other energies. The test of factorization at the p → p π + π − vertex is well verified. The process p p → Δ ++ Δ ++ is studied and the cross sections of Δ ++ , Δ ++ , ϱ 0 and f 0 production are also given.

Z.Phys.C 8 (1981) 283, 1981.
Inspire Record 155144 DOI 10.17182/hepdata.41428

New data on the inclusive production of the non-strange resonances ϱ0(770), ω(783), ϕ(1020) andf(1270) inK− p interactions at 32 GeV/c are presented. The inclusive production cross sections are equal to (4.32±0.72) mb, (3.7±1.4) mb, (0.65±0.10) mb and (0.91±0.35) mb respectively. Estimates of the topological cross sections are also obtained. The invariant and non-invariantx-distributions for the vector mesons ϱ0 and ϕ indicate the prevalence of forward resonance production in the c.m. system. For the tensorf-meson the rapidity andx-distributions are presented. Thet′-distributions for ϱ0, ϕ, andf have exponential slopes of 0.6±0.1 GeV−2, 1.2±0.2 GeV−2, and 0.8±0.5 GeV−2 respectively. The exponential slope ofpT2-distribution of thef-meson is equal to (2.3±0.5) GeV−2.

A Study of Charged Pseudoscalar Meson Photoproduction From Hydrogen and Deuterium With 16-{GeV} Linearly Polarized Photons

Quinn, D.J. ; Rutherfoord, J.P. ; Shupe, M.A. ; et al.
Phys.Rev.D 20 (1979) 1553, 1979.
Inspire Record 140543 DOI 10.17182/hepdata.24208

The asymmetries in forward π−N, π−Δ, and K+−(Λ+Σ) photoproduction have been measured with a 16-GeV linearly polarized beam. The experimental method and the procedures for extracting cross sections and asymmetries from the data are discussed in detail. Information on the energy and momentum-transfer dependence of cross sections for natural- and unnatural-parity exchange, interference between exchanges of opposite G parity, and vector-meson dominance is obtained and discussed.
