The abstract, sentence by sentence

arXiv listing abstract v3. Results and the main claim are underlined; show every role.

We investigate the effects of a nonzero leptonic mixing angle $\theta_{13}$ on the solar neutrino day-night asymmetry. Using a constant matter density profile for the Earth and well-motivated approximations, we derive analytical expressions for the $\nu_e$ survival probabilities for solar neutrinos arriving directly at the detector and for solar neutrinos which have passed through the Earth. Furthermore, we numerically study the effects of a non-zero $\theta_{13}$ on the day-night asymmetry at detectors and find that they are small. Finally, we show that if the uncertainties in the parameters $\theta_{12}$ and $\Delta m^2$ as well as the uncertainty in the day-night asymmetry itself were much smaller than they are today, this effect could, in principle, be used to determine $\theta_{13}$.

The paper

Original abstract

We investigate the effects of a nonzero leptonic mixing angle $\theta_{13}$ on the solar neutrino day-night asymmetry. Using a constant matter density profile for the Earth and well-motivated approximations, we derive analytical expressions for the $\nu_e$ survival probabilities for solar neutrinos arriving directly at the detector and for solar neutrinos which have passed through the Earth. Furthermore, we numerically study the effects of a non-zero $\theta_{13}$ on the day-night asymmetry at detectors and find that they are small. Finally, we show that if the uncertainties in the parameters $\theta_{12}$ and $\Delta m^2$ as well as the uncertainty in the day-night asymmetry itself were much smaller than they are today, this effect could, in principle, be used to determine $\theta_{13}$.

Solar neutrino probes of the muon anomalous magnetic moment in the gauged $U(1)_{L_\mu-L_\tau}$
hep-ph 2020-06 conditional novelty 5.0 of 10

Reevaluated Borexino solar neutrino data exclude part of the parameter space in which a U(1)_{L_mu-L_tau} gauge boson explains the muon g-2 anomaly, and future xenon dark matter detectors can cover most of the remainder.
On the Properties of the Effective Jarlskog Invariant for Three-flavor Neutrino Oscillations in Matter
hep-ph 2019-08 accept novelty 4.0 of 10

The ratio of the matter-changed CP violation measure to its vacuum value is approximately the product of two two-flavor resonance factors, now derived more accurately and used to locate its peaks and dip.
Status of global fits to neutrino oscillations
hep-ph 2004-05 conditional novelty 4.0 of 10

Combining all 2004 neutrino oscillation data yields best-fit three-flavour parameters with sin^2(theta_13) below about 0.05 at 3 sigma and confirms that four-neutrino schemes cannot accommodate LSND alongside the rest.
Solar neutrinos and neutrino physics
hep-ph 2015-07 accept novelty 2.0 of 10

Solar neutrino data are consistently described by large-mixing-angle MSW conversion, with measured theta12 and Delta m^2_21 and a theta13 consistent with reactor experiments.
