Description

Recent experimental results have shown an excess of muons in extensive air showers produced by cosmic rays with energies above $10^{17}$ eV. In this work, I discuss how even small deviations from Lorentz-invariant physics could influence the interpretation of the current state of the so-called "muon puzzle."
