D0 experiment at Tevatron collider provides a unique possibility
to detect all types of B hadrons. Currently, the activity of the
B physics group of D0 is concentrated on the study of Bs and b-baryons, which are not accessible at b-factories. After a brief presentation
of performance of D0 experiment and its capabilities for the B physics,
the latest D0 results on the properties of Bs meson, such as
the average lifetime, lifetime difference between BsL and BsH and the oscillation Bs---> anti-Bs frequency, will be presented.
Finally, future perspectives of D0 experiment in B physics will be
discussed.
