AlbaNova Colloquium

Probes of the Early Universe

by Prof. Carlos Peña Garay

Europe/Stockholm
Description

After the discovery of neutrino masses by the neutrino oscillation experiments, next frontiers are the discovery of CP violation on the lepton sector, the Majorana nature of neutrinos and the cosmological neutrinos. I will discuss the current status of the HyperKamiokande experiment, including the JPARC neutrino bean, the ND280+ and IWCD near detectors and the 220 kton water Cherenkov Far Detector, with special focus on the Spanish contributions to the construction of the gigantic detector. I will also discuss the physics potential and challenges of neutrinoless double decay searches and in the observation of cosmologal neutrinos.  

About the speaker:

Professor Carlos P. Garay is the Director of the Canfranc Underground Laboratory, one of the Singular Scientific and Technical Installations in Spain. He earned his PhD in Theoretical Physics at the University of Valencia in 2002, after which he became a Long Term Member at the Institute for Advanced Studies in Princeton. He got a faculty research position at CSIC, the largest research institution in Spain, in 2006. His research is focused on neutrino physics and astrophysics, currently coordinating the Spanish contribution to the construction of HyperKamiokande, a gigantic water Cherenkov detector combined with the JPARC neutrino beam, aiming at discovering CP violation in the lepton sector. Other research interests include axion searches with superconducting circuits and the impact of (the lack of) radiation in life underground. Since 2025, Carlos is serving as the General Assembly Chair of the AstroParticle Physics European Consortium, a funding agencies body with the mandate to develop a collective European strategy in Astroparticle Physics.
