We first quantize an action proposed by Casalbuoni and Gomis in 2014 that describes two massless relativistic scalar particles interacting via a conformally invariant potential. The spectrum is a continuum of massive states that may be interpreted as unparticles. We then obtain in a similar way the mass operator for a deformed action in which two terms are introduced that break the conformal symmetry: a mass term and an extra position-dependent coupling constant. A simple Ansatz for the latter…

Conformal symmetry for relativistic point particles
In this paper we consider conformal dynamics for a system of $N$ interacting relativistic massless particles. A detailed study is done for the case of two particles, with a particular attention to

In a previous paper [1], we have studied a conformal invariant model for two interacting relativistic particles. Our hypothesis was that the theory could be described in terms of the four-velocities

We consider scale invariant theories of continuous mass fields and show how interactions of these fields with the standard model can reproduce unparticle interactions. There is no fixed point or
