a neutral meson with a mass 10,507 times that of the electron and a mean lifetime of approximately 1.6 X 10-12 seconds.
Note two things: One this process is quite rare!, and Two it exists only through the exchange of more than one intermediate particle; these intermediate
Bs mesons oscillate 3 trillion times per second into their anti particle and back
