Dependence of the radio emission of air showers on the cosmic ray primary particle composition

• dr Washington Rodrigues Carvalho Jr.

Room: Room: B2.38 Abstract: We will start with brief introductions to Cosmic Rays (CR),extensive air showers and their radio emission. We will explore the origins of the dependence of the air shower development on the primary CR composition and how it affects the radio emission. We will then proceed to describe in more detail our newest work regarding a strong composition dependence on the measured radio signal amplitudes at ground level. This simple, yet historically overlooked dependence can be explained in terms of two competing scalings of the measured electric field that depend on the position of the shower maximum (Xmax) in the atmosphere. This dependence can be used to directly infer the CR primary composition, even on a non-standard event-by-event basis. Serdecznie zapraszamy dr hab. Katarzyna Grzelak prof. dr hab.
