Data on the 4π 0 decay mode of mesons have been obtained in a search for glueballs performed at the CERN SPS with the GAMS-4000 multiphoton spectrometer. A new tensor glueball candidate X(1810) appears as a clear peak in the 4π 0 mass spectrum. The 4π 0 decay of G(1590) is also observed. The measured value of BR(G→4 π 0 )/BR(G→ ηη )=0.8±0.3 further supports the glueball assignment of this scalar particle. The rate decay of f(1270) into 4π 0 has been measured: BR(f→4 π 0 ) = (3±1)×10 −3 .

Production of anti-D0 and D- Mesons in Neutron - Carbon Interactions at 40-GeV to 70-GeV

The BIS-2 collaboration Aleev, A.N. ; Arefev, V.A. ; Balandin, V.P. ; et al.

The production of$\bar D$ mesons in neutroncarbon interactions at 40–70 GeV/c has been investigated. The$\bar D$ mesons were detected via the hadronic decay modes$\bar D^0\to K^{* + } (892)\pi ^ -$ andD−→K*+(892)π−π−. In the kinematical regionxF>0.5 andpT<1 GeV/c the following inclusive cross sections were measured:$\sigma _{\bar D^0 }= (28 \pm 14)\mu b$ and$\sigma _{D^ -}= (28 \pm 13)\mu b$ per carbon nucleus. The invariant longitudinal momentum spectra can be described by (1−x)N with$N_{\bar D^0 }= 1.1 \pm 0.5 \pm 0.4$ and$N_{D^ -}= 0.8 \pm 0.4 \pm 0.4$ The transverse momentum spectra were parametrized by exp (−BpT2) with$B_{\bar D^0 }= (1.2_{ - 0.9}^{ + 1.1} )({{GeV} \mathord{\left/ {\vphantom {{GeV} c}} \right. \kern-\nulldelimiterspace} c})^{ - 2} $ and$B_{D^ -}= (1.8_{ - 1.0}^{ + 1.3} )({{GeV} \mathord{\left/ {\vphantom {{GeV} c}} \right. \kern-\nulldelimiterspace} c})^{ - 2} $.
