Abstract

Measurement of the $B^0_s$ oscillation frequency via $B^0_s$ mixing analysis provides a powerful constraint on CKM matrix elements. This note briefly reviews the motivation behind these analyses and describes the various steps that go into a mixing measurement. Recent results on $B^0_s$ mixing obtained by the CDF and D{\O}collaborations using the data samples collected at Tevtron Collider in the period 2002 - 2005 are presented.
