Measurement of the B-0(B)over-bar-(0) oscillation frequency using l(-)D *(+) pairs and lepton flavor tags Academic Article uri icon

abstract

  • The oscillation frequency md of B0B0 mixing is measured using the partially reconstructed semileptonic decay B0l-D*+X. The data sample was collected with the CDF detector at the Fermilab Tevatron collider during 1992-1995 by triggering on the existence of two lepton candidates in an event, and corresponds to about 110 pb-1 of pp collisions at s=1.8 TeV. We estimate the proper decay time of the B0meson from the measured decay length and reconstructed momentum of the l-D*+ system. The charge of the lepton in the final state identifies the flavor of the B0 meson at its decay. The second lepton in the event is used to infer the flavor of the B0 meson at production. We measure the oscillation frequency to be md=0.516 0.099-0.035+0.029 ps-1, where the first uncertainty is statistical and the second is systematic. 1999 The American Physical Society.
