For a small amplitude interference will dominate..

There will only be three terms as mm => 0

If we average over acoplanarity we only get the first term

This is the term that created our forward-backward asymmetry!

If our model is right:

• The asymmetry should be proportional to sin2ql

• The asymmetry should have a Q2 dependence given by Q2 H02(Q2)
