Abstract content

ANITA is a balloon-borne radio receivers designed to register RF (50-1000 MHz) signals produced by UHECR. The RF signals produced in the collision of UHECR particles with atmospheric molecules are explained as the combined result of the Askaryan effect and the geomagnetic signal resulting from Earth’s magnetic field. These signals subsequently get reflected off the Antarctic surface and back up to the ANITA detector at an altitude of 38 Km. We develop a rigorous theoretical framework based on Weyl formalism to model the reflection and refraction properties of these radio pulses generated by HiCal transmitter, incorporating curvature of Earth and surface roughness (arXiv:1801.08909,(2018)). Our formalism is the first complete model that properly explains the reflection properties of radio pulses from a spherical surface without relying on any uncontrolled approximations. We seek to understand the mystery events detected by ANITA, which can lead to breakthrough discovery of new physics.
