Highest energy particle physics with the Pierre Auger Observatory
A. G. MARIAZZI FOR THE PIERRE AUGER COLLABORATION
Conferencia; XXXIII Symposium on Physics in Collision; 2013
Astroparticles offer a new path for research in the field of particle physics, allowing inves-tigations at energies above those accesible with accelerators. Ultra-high energy cosmicrays can be studied via the observation of the showers they generate in the atmosphere.The Pierre Auger Observatory is a hybrid detector for ultra-high energy cosmic rays,combining two complementary measurement techniques used by previous experiments,to get the best possible measurements of these air showers. Shower observations enableone to not only estimate the energy, direction and most probable mass of the primary cos-mic particles but also to obtain some information about the properties of their hadronicinteractions. Results that are most relevant in the context of determining hadronic in-teraction characteristics at ultra-high energies will be presented.
