Is it possible to find a particle theory that behaves like a string theory? In this talk I review attempts to do this in the past and present more recent activity that uses the world line description of particle physics. This formalism allows the definition of a class of world-line theories that have the same UV complete properties as string theory. It turns out that these theories are related to a class of ghost-free infinite derivative theories inspired by string field theory. It is also possible to find particle theories that reproduce the dominant behaviour of string scattering amplitudes at high energies.

This talk is part of the HEP phenomenology joint Cavendish-DAMTP seminar series.
