Open Beauty Production in High-energy $\pi^-$ - Tungsten Interactions

The NA10 collaboration Bordalo, P. ; Busson, P. ; Kluberg, L. ; et al.
Z.Phys.C 39 (1988) 7, 1988.
Inspire Record 260719 DOI 10.17182/hepdata.15616

We present a study of\(B\bar B\) meson pair production inπ− interactions at 140, 194 and 286 GeV incident pion energy. At 286 GeV, where we have the best statistics, we find a model-dependent\(B\bar B\) production cross-section\(\sigma _{BB}= 14_{ - 6}^{ + 7} nb/nucleon\).

The Production of Beauty Particles in $\pi^-$ U Interactions at 320-{GeV} Energy

The WA78 collaboration Catanesi, M.G. ; Muciaccia, M.T. ; Natali, S. ; et al.
Phys.Lett.B 187 (1987) 431-436, 1987.
Inspire Record 235069 DOI 10.17182/hepdata.6522

B B production in π − -uranium interactions has been observed at 320 GeV beam energy looking at events with three muons in the final state. The cross section is found to be σ B B = 4.5±1.4±1.4 nb per nucleon (for a linear A -dependence) or σ B B = 17.6±5.5±5.5 nb per nucleon (assuming A 0.75 dependence). An estimate of x F distribution is given.
