12. Novel Neutrino Self-interaction Can Save Sterile Neutrino Dark Matter

Prof. Yue Zhang

Sterile neutrino, a gauge-singlet fermion with a small active neutrino mixture, is a simple and one of the oldest dark matter candidates. In its first incarnation, proposed by Dodelson and Widrow, sterile neutrino dark matter can be produced via neutrino oscillation in the early universe, which is a very elegant mechanism. However, it has been completely ruled out by astrophysical observations...

32. New Physics Opportunities at Tau Neutrino Experiments

Prof. Seodong Shin (Jeonbuk National University)

25/05/2024, 14:25

In this talk, I will discuss the potential of current/future tau neutrino experiments in probing new physics beyond the Standard Model. A focus will be given to a tau neutrino-philic new particle that can play an important role in the evolution of early Universe.

27. Matter Effect on the Flavor Composition of Astrophysical Neutrinos

Bhupal Dev (Washington University in St. Louis)

The sources of the high-energy neutrino events detected by IceCube remain largely unknown. A more precise neutrino flavor ratio measurement in the future will be crucial in resolving this open question. We discuss how the flavor ratio gets modified in presence of matter effects for Active Galactic Nuclei (AGNs) which are currently the most promising astrophysical candidate sources. We show...

42. Probing New Physics with Double Beta Decay

Prof. Frank F Deppisch

Neutrinoless double beta decay is the primary means with which we can probe a potential Majorana nature of light neutrinos. Planned experiments searching for this hypothetical decay aim to be sensitive to half-lives of up to 10^28 years, allowing to probe Majorana neutrino mass scales of O(10 meV). It is also well established that neutrinoless double beta decay receives contributions beyond...
