Query: Hadronic models of the Fermi bubbles: Future perspectives   The origin of sub-TeV gamma rays detected by Fermi-LAT from the Fermi bubbles
at the Galactic center is still unknown. In a hadronic model, acceleration of
protons and/or nuclei and their subsequent interactions with gas in the bubble
volume can produce observed gamma rays. Such interactions naturally produce
high-energy neutrinos, and detection of those can discriminate between a
hadronic and a leptonic origin of gamma rays. Additional constraints on the
Fermi bubbles gamma-ray flux in the TeV range from recent HAWC observations
restrict hadronic model parameters, which in turn disfavor Fermi bubbles as the
origin of a large fraction of neutrino events detected by IceCube along the
bubble directions. We revisit our hadronic model and discuss future constraints
on parameters from observations in very high-energy gamma rays and neutrinos.
