Abstract

We discuss the prospects for production and detection of fermiophobic bosons (exotic bosons decaying only to standard model gauge bosons) at the LHC, and describe simple methods for determining spin. We consider two complementary approaches to spin determination: the search for decays in the diphoton channel, and the comparison of events with no extra spectator jets to those with one extra jet. We show that these approaches can together allow the fermiophobic bosons spin to be determined over a wide range of parameter space. We study both even and odd parity states.
