A partial-wave analysis of the low-mass ( π + π − p) system produced in the reaction K − p → K − ( π + π − p) at 4.2 GeV/ c incident momentum is performed in order to study the two ( π + π − p) enhancements around 1500 and 1700 MeV. It is found that the low-mass ( π + π − p) system can be described using the spin-parity states J P = 1 2 + , 3 2 − and 5 2 + only. In the 1500 MeV region contributions are observed from the 1 2 + wave decaying into pϵ and the 3 2 − wave decaying into Δ ++ π − ; in the 1700 MeV region contributions are found from the 1 2 + wave decaying into Δ ++ π − , the 3 2 − wave decaying into pϵ, and the 5 2 + wave decaying into pϵ.

Photoproduction of rho0 and rho- Mesons at 3-GeV

Phys.Rev.D 15 (1977) 26, 1977.
Inspire Record 123802 DOI 10.17182/hepdata.24621

The photoproduction of ρ0 and ρ− mesons has been studied at 3 GeV in the reactions γd→dπ±π−, γd→psnπ+π−, and γd→pspπ−π0. For ρ0 and ρ− production in these reactions we present the total and differential cross sections, the decay angular distributions, and the spin density matrix elements. The photoproduction of the ρ0 is found to be consistent with s-channel helicity conservation and is dominated by natural-parity exchange. The ρ− meson production has approximately equal natural- and unnatural-parity-exchange contributions. The unnatural-parity-exchange contribution is consistent with one-pion exchange and is used to estimate the value of Γρπγ.

Charged current data of a spark chamber neutrino experiment at the 70 GeV Serpukhov accelerator (10 200 events in the v beam and 3600 events in the v beam with energies up to 30 GeV) have been analyzed. Total neutrino and antineutrino cross sections and v -distributions are obtained.

Inclusive Muon Production in $e^+ e^-$ Annihilation with $\sqrt{s}$ = 7.3-GeV

Badtke, D.H. ; Barnett, B.A. ; Jones, L.H. ; et al.
Phys.Rev.Lett. 40 (1978) 827, 1978.
Inspire Record 134548 DOI 10.17182/hepdata.20890

We present results on charged multiplicity nch=2 and nch>2 muon events produced in e+e− collisions with 〈s12〉=7.3 GeV at 90° to the beams. The background-subtracted inclusive cross section for the nch=2 events is 10.2±5.4 pb/sr, in agreement with the expected contribution from the heavy lepton τ. The cross section for the nch>2 events is 19.0±6.5 pb/sr whereas we expect only 2.9 pb/sr from the τ, indicating that we may be seeing the weak decays of charmed mesons.
