The Physics of Beauty


  • The interest in this field has been triggered by the problem of B°-B° bar mixing. The analysis has concentrated in the semi-leptonic decay channel for which the know-how from the HPC data analysis has been particularly useful.
  • Later on, the increased statistics suggested to move toward the study of the Bs-meson, identified through its decay into Ds. The B lifetime has been measured accurately.
  • The same methods used for the determination of the lifetime have also been applied to the study of the time-dependent oscillations. The difference between the two mass eigenstates BS -BL has been measured (actually only its lower limit has been determined so far).
