Forward-backward asymmetries in W and Z decays
The leptons emitted in decays of W and Z bosons produced in pp or anti pp collisions exhibit characteristic asymmetries with respect to the beam direction, as measured in the W or Z center-of-mass. The asymmetries appear in both pp and anti pp collisions. For anti pp collisions they appear to be approximately constant over the whole y range for values of M/..sqrt..s greater than or equal to 0.1. For smaller values of M/..sqrt..s, the asymmetries become more and more washed out in the central region as sea-sea collisions begin to play a larger role in gauge boson formation.
