MEASUREMENT OF THE INCLUSIVE BRANCHING FRACTION tau- ---> tau-neutrino pi- pi0 NEUTRAL MESON(S)

The TPC/Two Gamma collaboration Aihara, H. ; Alston-Garnjost, M. ; Avery, R.E. ; et al.
Phys.Rev.Lett. 57 (1986) 1836, 1986.
Inspire Record 233422 DOI 10.17182/hepdata.38106

We measure an inclusive branching fraction of (13.9 ± 2.0−2.2+1.9)% for the decay τ−→ντπ−π0+nh0(n>~1), where h0 is a π0 or an η. The data sample, obtained with the time-projection-chamber detector facility at the SLAC e+e− storage ring PEP, corresponds to an integrated luminosity of 72 pb−1 at 29 GeV center-of-mass energy. The measured branching fraction is somewhat greater than the theoretical prediction and, with errors taken into account, could resolve the present difference between the inclusive and the sum of the exclusive τ± branching fractions into one charged prong.

Search for high mass narrow resonances in virtual photon photon interactions

The TPC / TWO GAMMA collaboration Aihara, H. ; Alston-Garnjost, M. ; Avery, R.E. ; et al.
Phys.Rev.Lett. 57 (1986) 3245-3248, 1986.
Inspire Record 239032 DOI 10.17182/hepdata.20201

We report on the first search with virtual photon-photon collisions for narrow, neutral resonances with even C parity in the mass range 4.5<W<19 GeV. The data were obtained via the process e+e−→e+e−γ*γ*→e e−+R with both the scattered e+ and e− detected. We find upper limits (95% confidence level) for the partial decay width of a resonance into two photons, ranging from 50 keV at W=4.5 GeV to 10 MeV at W=19 GeV. These limits constrain theoretical models involving neutral composite bosons.

PARTIAL WAVE ANALYSIS OF THE K+ PI+ K- SYSTEM SEEN IN THE REACTION PI+ P ---> K+ PI+ K- P AT 11.46-GeV/c

Leedom, I.D. ; DeBonte, R.J. ; Gaidos, J.A. ; et al.
Phys.Rev.D 27 (1983) 1426, 1983.
Inspire Record 194990 DOI 10.17182/hepdata.23837

We present results of a hybrid-bubble-chamber experiment examining the reaction π+p→π+pK+K− at an incident momentum of 11.46 GeV/c. The total cross section for this channel is determined to be 87.2±6.4 μb. A partial-wave analysis of the K+π+K− system reveals no unambiguous evidence of resonant activity, although mass enhancements are noted in the JP=0− κ¯K+ (S wave), JP=2− fπ (S wave), and JP=2−, K¯*0(892)K+ (P wave). This is the first published report of the relative phases of the waves seen in this reaction. We comment on the influence this channel may have on A1 and A3 production.
