Estimate
What is known
~700K events of φ from pK+(K-) final state in g11
φ decays to K+K- with BR 0.49
φ decays to γη with BR 0.013
φ decays to γω < 5%
Feasibility
Assume pK+ acceptance ~10%, total φ produced ~ 7M in pφ exclusive production
set the final state particles are pγπ+π- and the acceptance is ~0.0003 with assumption that charged particle ~30% acceptance and photon ~10%
expect η from φ ~30 events
expect ω from φ ~110
