Like the weak interaction itself, the Higgs coupling to the left chiral components of the Dirac bispinors for quarks "knows" which up goes with which down in the universal coupling. However, the simple conjecture that the right chiral components of each are not so distinguished provides for a consistent determination of the quark mass spectra and of

Upcoming cosmological surveys will probe the impact of a non-zero sum of neutrino masses on the growth of structures. These measurements are sensitive to the behavior of neutrinos at cosmic distances, making them a perfect testbed for neutrino physics beyond the standard model at long ranges.

The talk will still be about the same generalization of QM but more focused on the difference in the interference pattern of two paths in canonical QM vs. this generalization of QM. The reason for this change is that I have made much more progress in this aspect than the topic of my current abstract. As such, I believe it would be more fruitful to talk about this work as opposed to...

In this talk, we discuss the cosmological effects of a tower of neutrino states (equivalently a tower of warm dark matter ) on cosmic microwave background (CMB) and large-scale structure. For concreteness, we considered the $N$-Naturalness model which is a proposed mechanism to solve the electroweak Hierarchy problem. The model predicts a tower of neutrino states, which act as warm dark...

Identification of high-energy neutrino point sources by IceCube is exciting for particle phenomenology, as propagation of neutrinos over large distances allows us to test properties that are hard to access. However, beyond-Standard Model effects would often show up as distortions of the energy spectrum, which makes it difficult to distinguish new physics from uncertainties in the source...

The Deep Underground Neutrino Experiment (DUNE) is a long baseline oscillation experiment that, among its many physics goals, seeks to measure the charge-parity (CP) violating phase, $\delta_{\mathrm{CP}}$. To do so requires precise knowledge of both the neutrino and antineutrino fluxes. DUNE will achieve this via the use of both a near and far detection system. The leading source of...

The scenario of neutrino self-interactions is an interesting beyond-Standard Model possibility that is difficult to test.

This result was computed by treating the Earth as flat. In this talk, I revisit...
