【 摘 要 】

This document describes the measurements of the B0and B0smixing frequencies performed at LHCb using the data sample corresponding to an integrated luminosity of 1 fb-1collected during 2011. The knowledge of the mixing frequencies provides a constraint on the apex of the CKM unitarity triangle and is a key ingredient for several CP-violation measurements. Analyses of the flavour oscillations allow also to measure the B0and the B0sproduction asymmetries.
