The upgrade program of the Large Hadron Collider (LHC) was implemented during the second Long Shutdown program (2019/2020). For this program, the ALICE Collaboration (A Large Ion Collider Experiment) proposed, among others, a new detector called Muon Forward Tracker (MFT). The primary goal of the MFT detector, installed on December 2021 and located between the Inner Tracker System (ITS) and the Muon Spectrometer, is to improve the capability of vertex reconstruction. The MFT is equipped with the same pixel sensors used for the ITS upgrade. These sensors are the ALICE Pixel Detectors (ALPIDE), a kind of monolithic active pixel sensor. The MFT is composed of five arrays of pixel sensors which are configured as parallel discs covering −3.6 < η < −2.45. Some prototypes were designed in order to achieve the final version of the ALPIDE, such as the pALPIDE family, which was divided into t...

Los rayos cósmicos de energía ultra alta son detectados por el Pierre Auger Observatorio en el hemisferio sur y por el Telescope Array Experiment en el uno del norte. La distribución de las direcciones de llegada de estas partículas en la esfera celeste proporciona información relevante para investigar el origen, la composición química y los mecanismos de producción de estas partículas. La comparación de la direcciones de llegada son realizadas por métodos estadísticos.
