In recent times, finite fields and functional reconstruction techniques have been proven capable of tackling very challenging problems in the field of scattering amplitudes. In this focused workshop, a small number of experts in the field will gather, in an informal environment, to discuss current approaches and possible future applications relevant to quantum field theory and precision LHC physics.  It will consist of a limited number of talks and open discussion sessions.  We also plan to dedicate some time to demonstrate some examples of applications of these techniques.

Participation is by invitation only.
