571. Ultra-High-Energy Neutrino Anomaly across Anita-IV, KM3NeT, and IceCube

Dibya Sankar Chattopadhyay (Oklahoma State University)

7/7/26, 9:00 AM

Speaker: Dibya Sankar Chattopadhyay
Abstract: The ANITA-IV experiment has reported four anomalous upgoing neutrino-candidate events with energies above 1 EeV and arrival directions implying propagation through at least several hundred kilometers of Earth. More recently, the KM3NeT Collaboration reported KM3-230213A, an exceptionally energetic event consistent with a parent neutrino in the...

572. Cosmological constraints on pseudo-Dirac neutrinos

Chee Sheng Fong (Universidade Federal do ABC)

7/7/26, 10:00 AM

Speaker: Chee Sheng Fong
Abstract: In this talk, I will review the possibility of neutrinos being pseudo-Dirac and discuss cosmological constraints from CMB and BBN on this scenario.
