Abstract
Mesons comprising a beauty quark and a strange quark can oscillate between
particle (B0s) and antiparticle (B0s) flavour eigenstates, with a frequency
given by the mass difference between heavy and light mass eigenstates, deltams.
Here we present ameasurement of deltams using B0s2DsPi decays produced in
proton-proton collisions collected with the LHCb detector at the Large Hadron
Collider. The oscillation frequency is found to be deltams = 17.7683 +- 0.0051
+- 0.0032 ps-1, where the first uncertainty is statistical and the second
systematic. This measurement improves upon the current deltams precision by a
factor of two. We combine this result with previous LHCb measurements to
determine deltams = 17.7656 +- 0.0057 ps-1, which is the legacy measurement of
the original LHCb detector.
