High Energy Seminar
A New Way to Measure Spin at Hadron Colliders
Date: Monday, September 27th
Time: 4:00 pm
Place: 4274 Chamberlin (Coffee and Cookies at 3:45 pm)
Speaker: Matthew Buckley, Fermilab
Abstract: I propose a new technique for determining the spin of new massive particles
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.
