Plenary

PHENIX has finished data collection in 2016, but the analysis of the vast amount of unique data are still ongoing, resulting in a steady flow of publications bearing on the most current physics issues related to the nature of QGP and nuclear structure. The versatility of the PHENIX detector, combined with the diversity of collision systems available at RHIC has allowed the exploration of...

517. NA64: The dark matter experiment at the CERN SPS

Marco Ayala (SAPHIR - UNAB)

Plenary

NA64 is an active target experiment that utilizes high-intensity electron, positron, and muon beams generated by the collision of high-energy protons from the CERN Super Proton Synchrotron (SPS) with a target and subsequently guided to the NA64 detector. The experiment primarily employs the missing energy technique to search for dark matter particles in the sub-GeV mass range and other physics...

490. Low scale seesaw theories and their phenomenology

Dr Antonio Enrique Cárcamo Hernández (Universidad Técnica Federico Santa María)

06/01/2025, 15:40

Plenary

I will describe theories with low scale seesaw mechanisms implemented to generate the SM fermion mass hierarchy. In the first part of my talk, I will explain an extended 2HDM theory where the tree level Universal seesaw and Zee-Babu mechanisms generate the SM charged fermion mass hierarchy and tiny active neutrino masses, respectively. The theory is consistent with SM fermion masses and...
