Description
The identification of the correct model for physics beyond the Standard Model
requires the determination of the spin of new particles.
We investigate to which extent the spin of a new particle $X$ can be identified in scenarios where this
particle decays dominantly via three-body decays $X\rightarrow f\overline{f} Y$
where we assume that all intermediate particles are heavy and the particle $Y$ is a
candidate for dark matter and escapes direct detection at a high energy collider such as the LHC.
We develop a model-independent strategy based on the invariant
mass distribution of the two SM-fermions $m_{ff}^2$ and show how spin
assignments for $X$ and $Y$ can be supported or excluded independent of the
couplings.
