SEARCH FOR STRANGE BARYONIUM STATES IN ANTI-P D INTERACTIONS AT 8.9-GEV/C

Shoemaker, G.H.N. ; Ko, W. ; Michael, W. ; et al.

A search for SU(3) manifestly exotic Q2Q¯ 2 baryonium states in antiproton-deuterium interactions was carried out at the SLAC 40-in. hybrid bubble-chamber facility. The I=(3/2, S=1 channel, X−, produced in conjunction with a forward produced neutral antikaon was studied. Such X− states would decay into an antihyperon and a baryon. The fast forward K¯ 0 was detected in a three-view segmented calorimeter placed downstream of the bubble chamber and used as part of the trigger. Upper limits of 0.50–1.63 μb are reported for the X−→Λ¯nπ−, Σ¯ n−, Λ¯pπ−π−, Σ¯ π−−, Σ¯ π∓±π− exclusive channels based upon ≤13 events per channel.

Pion and kaon pair production in photon-photon collisions

We report measurements of the two-photon processes e+e−→e+e−π+π− and e+e−→e+e−K+K−, at an e+e− center-of-mass energy of 29 GeV. In the π+π− data a high-statistics analysis of the f(1270) results in a γγ width Γ(γγ→f)=3.2±0.4 keV. The π+π− continuum below the f mass is well described by a QED Born approximation, whereas above the f mass it is consistent with a QCD-model calculation if a large contribution from the f is assumed. For the K+K− data we find agreement of the high-mass continuum with the QCD prediction; limits on f′(1520) and θ(1720) formation are presented.

EXCLUSIVE PRODUCTION OF K+ K- pi+ pi- IN PHOTON-PHOTON COLLISIONS

The TPC/Two Gamma collaboration Aihara, H. ; Alston-Garnjost, M. ; Armitage, J.C. ; et al.
Phys.Rev.Lett. 54 (1985) 2564, 1985.
Inspire Record 213402 DOI 10.17182/hepdata.20345

We report a measurement of the reaction γγ→K+K−π+π− in both tagged and untagged events at PEP. The cross section rises with invariant γγ mass to about 15 nb at 2 GeV and falls slowly at higher masses. We find clear evidence for the processes γγ→φπ+π− and γγ→K*0(892)Kπ. Upper limits (95% C.L.) of 1.5 and 5.7 nb in the mass range from 1.7 to 3.7 GeV are obtained for φρ0 and K*0K¯*0 production, respectively.
