LHC forward (LHCf) experiment measures forward neutral particles to improve hadronic interaction models adopted in cosmic-ray air shower simulations. This summer, we plan to have a data taking in proton-proton collisions. We expect ten times larger statistics than the previous operation in 2015 which allows us to measure pi0 and eta mesons more precisely. Moreover, we plan to have a joint operation with the ATLAS Zero degree calorimeter in this operation.
Improvements in energy resolution for hadrons are expected by the joint operation and allow us to select the one-pion exchange process. In this talk, we present the prospects of the next LHCf operation.
