Estimate

What is known

~700K events of φ from pK+(K-) final state

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
