With observations of solar neutrinos in direct dark matter detection, the search for dark matter is beginning to fog. This irreducible neutrino fog presents an new probe into neutrino physics. In this talk, we explore the potential of current and next-generation xenon-based detectors to constrain and discover non-standard neutrino interactions (NSI). We present new limits on NSI couplings and...
The ultra-high-energy event KM3--230213A has been attributed
to dark matter (DM) decay, despite arriving opposite the
Galactic Centre. We construct a per-event test statistic to
quantify this hypothesis and forecast the events needed to exclude
it in favour of an isotropic signal. The single observed event
disfavours but does not exclude DM decay ($p_{\rm DM}\simeq0.13$--$0.15$)....
Determining the leptonic CP-violating phase $\delta_{\rm CP}$, the atmospheric mixing angle $\theta_{23}$, and the mass-squared difference $\Delta m^2_{31}$ with high precision is a central goal of current and next-generation long-baseline neutrino experiments. In this work, we investigate the fundamental information content of three-flavor neutrino oscillations within the framework of quantum...
We demonstrate for the first time that new physics explaining the long standing charged $B$ meson anomalies, $R(D^{(*)})$, can be the source of CP violation that explains the observed baryon asymmetry of the universe (BAU). We consider the general two Higgs doublet model with complex Yukawa couplings and compute the BAU in the semiclassical formalism, using a novel analytic approximation for...
