Description
The SuperB accelerator will be an asymmetric heavy flavour factory
where e+, e- beams will collide with a peak luminosity of 10^36 cm-2 s-1
at the Y(4S) resonance c.m. energy of 10.58 GeV. The B-Bbar meson pairs,
produced with a B.R. > 96% from the decay of the Y(4S), will allow to
measure the B-meson decay channels with unparalled precision.
The SuperB e+, e- beams are characterized, at the interaction region
(I.P.), by transversal dimensions of only few microns. This fact could
open the possibility to put very close to the I.P. a suitable shaped
target to intercept the negative B mesons before their decay. As a result of the
interaction of the slow negative B mesons with the nucleons of the target
nuclei, baryons with beauty, as the LAMBDAb and the SIGMAb/SIGMA*B, can be
produced with high cross section. A production rate in excess of 2000
heavy baryons per day per nucleon seems achievable. If confirmed, this
would allow a systematic study of the properties of the heavy baryons with
beauty (for which not so many data exist) and, furthemore, to investigate
their interactions with nucleons in nuclei, a topic totally unexplored
until now. The possibility to implement such a configuration on the SuperB
will be discussed and the results of preliminary calculations presented.
