SUMMARY:A New Way to Measure Spin at Hadron Colliders\, High Energy Se
 minar\, Matthew Buckley\, Fermilab
DESCRIPTION:I propose a new technique for determining the spin of new 
 massive particles<br>
\nthat might be discovered at the Large Hadron C
 ollider. The method relies on<br>
\npair-production of the new particl
 es in a kinematic regime where the vector<br>
\nboson fusion productio
 n mechanism is enhanced. For this regime\, I show that<br>
\nthe distr
 ibution of the leading jets as a function of their relative<br>
\nazim
 uthal angle can be used to distinguish spin-0 from spin-1/2 particles.
  I<br>
\nillustrate this effect by considering the particular cases of
  (i)<br>
\nstrongly-interacting\, stable particles and  (ii) supersymm
 etric particles<br>
\ncarrying color charge. I argue that this method 
 should be applicable in a<br>
\nwide range of new physics scenarios.
