Talk:Scattering amplitude

What is this about?

I see this phrase 'Scattering Amplitude' appearing r.e. 'feynman diagrams' and 'string theory' (r.e. that tripple integral over possible paths, time, sigma .. i.e. across the possible worldsheets).

This article seems to define the term r.e. something very specific about 'incoming planar waves, outgoing spherical waves' (something deflected ..).

for reference -

• 'scattering amplitude' http://muellergroup.lassp.cornell.edu/scatter.pdf
• 'scattering amplitude'/'feynman diagrams' [1]
• 'scattering amplitude'/'string theory' [2]

Should this article be .. "a scattering amplitude is ..." ; "basic scattering ...:'..." "in string theory: ..."
