that might be discovered at the Large Hadron Collider. The method relies on
pair-production of the new particles in a kinematic regime where the vector
boson fusion production mechanism is enhanced. For this regime, I show that
the distribution of the leading jets as a function of their relative
azimuthal angle can be used to distinguish spin-0 from spin-1/2 particles. I
illustrate this effect by considering the particular cases of (i)
strongly-interacting, stable particles and (ii) supersymmetric particles
carrying color charge. I argue that this method should be applicable in a
wide range of new physics scenarios.
