Resumen:
p { margin-bottom: 0.08in; } The mass composition of ultra-high energy cosmic rays is a critical issue to understand their origin and nature. The Pierre Auger Observatory is a hybrid instrument which provides a powerful environment for the determination of the primary mass. The Observatory is located in Malargue (Argentina) and consists of 1660 water Cherenkov detectors equally spaced on a triangular grid (1.5 km) over an area of approximately 3000 km2. Overlooking at the array there are 4 different sites with 6 Fluorescence Detector telescopes. Different parameters sensitive to the primary mass are discussed. Their energy dependence and a comparisons with predictions from different models are also presented.
