|
These processes represent the production of a $Z$ boson (or virtual photon)
|
|
which subsequently decays leptonically, in association
|
|
with a $b{\bar b}$ pair. The effect of
|
|
the bottom quark mass is included throughout the calculation.
|
|
The calculation may be performed at LO only, because the one-loop
|
|
calculation with massive quarks has not yet been performed.

|
When {\tt removebr} is true, the $Z$ boson does not decay.
