In this seminar I will describe some of the hidden structures recently
discovered in the scattering amplitudes of elementary particles, such
as those measured at the Large Hadron Collider. These structures are
responsible for the mysterious simplicity of these quantities, which is
completely obscured by a calculation based on textbook techniques
such as Feynman diagrams. I will then move on to discuss form factors. These are slightly off-shell quantities and, similarly to amplitudes,
are also much simpler than what expected based on conventional
approaches. In particular I will focus on form factors of particular (half-BPS) operators in a special theory, known as N=4 super Yang-Mills, and briefly discuss some unexpected connections
to scattering amplitudes in phenomenologically relevant theories.
