Reconstructing the cosmic-ray energy from the radio signal measured in one single station

Understand

Short radio pulses can be measured from showers of both high-energy cosmic rays and neutrinos.

• While commonly several antenna stations are needed to reconstruct the energy of an air shower, we describe a novel method that relies on the radio signal measured in one antenna station only.
• Exploiting a broad frequency bandwidth of $80-300$ MHz, we obtain a statistical energy resolution of better than 15\% on a realistic Monte Carlo set.
• This method is both a step towards energy reconstruction from the radio signal of neutrino induced showers, as well as a promising tool for cosmic-ray radio arrays.
