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
\nthat might be discovered at the Large Hadron C
ollider. The method relies on
\npair-production of the new particl
es in a kinematic regime where the vector
\nboson fusion productio
n mechanism is enhanced. For this regime\, I show that
\nthe distr
ibution of the leading jets as a function of their relative
\nazim
uthal angle can be used to distinguish spin-0 from spin-1/2 particles.
I
\nillustrate this effect by considering the particular cases of
(i)
\nstrongly-interacting\, stable particles and (ii) supersymm
etric particles
\ncarrying color charge. I argue that this method
should be applicable in a
\nwide range of new physics scenarios.
