SUMMARY
Bhabha scattering, represented by the process e+ e- → e+ e-, involves only two leading order Feynman diagrams: the s-channel and t-channel diagrams. The s-channel diagram corresponds to the reaction AB → CD, while the t-channel diagram represents AC → BD. The u-channel diagram, which involves Moller scattering (e+ e+ → e+ e+), does not contribute to Bhabha scattering. The concept of "crossing" in Feynman diagrams refers to the rotation of the diagram rather than the literal crossing of lines.
