UHECR measurements and physics at man-made accelerators: mutual constraints

TL;DR

This paper discusses how ultra-high-energy cosmic ray (UHECR) measurements and accelerator experiments mutually constrain each other, highlighting the importance of new observations to advance understanding of hadronic interactions.

Contribution

It provides an analysis of the mutual constraints between UHECR observations and accelerator data, emphasizing the need for further measurements in both fields.

Findings

UHECR measurements inform hadronic interaction models.

Accelerator data complement cosmic ray observations.

Further experiments are crucial for advancing the field.

Abstract

Measurements of the products of UHECR interactions with the Earth's atmosphere, as obtained in Extended Air Shower experiments, offer important information concerning hadronic interactions, which for some aspects overlaps and for many others complements the information extracted by measurements of collisions at human-made accelerators. In this contribution I discuss some of the constraints that the UHE astroparticle and accelerator fields exercise one over each other, emphasizing the importance of further new measurements, through new experiments or observations, in both fields.
