Description
The Pierre Auger Observatory first reported the excess of the measured number of muons compared to that in the simulation in 2015, which was confirmed by the following analysis with other experiments. This revealed the muon puzzle, which might be caused by some unknown mechanism suppressing the neutral pion productions in an air shower. Several scenarios are proposed, including the strangeness enhancement scenario, which suppresses pion production and increases kaon production. To conclude this puzzle, these scenarios must be tested experimentally.
In this simulation study, we use the MCEq simulation package to demonstrate two important points for experimentally testing a strangeness enhancement scenario.
First, we highlight the interactions that should be measured from huge interactions ranging from O(0.1) GeV to O(10) EeV in an air shower. Several forward experiments at the LHC have been found to cover the crucial interactions we need to measure. Second, we assessed the required precision to rule out the scenario if no strangeness enhancement is measured in future analyses of forward experiments. These results are essential for constructing the analysis in the current forward experiment and for designing future forward experiments at the LHC.
