The authors' main claim The Super-K data of oscillation of multi-GeV atmospheric neutrinos can be used to put an upper bound on coupling $\alpha_{e\tau}< 6.4 \times 10^{-52}$ and $\alpha_{e\mu}< 5.5 \times 10^{-52}$at 90% CL when the range of the force is the earth-sun distance.

In the minimal standard model it is possible to gauge any one of the following global symmetries in an anomaly free way: (i)$L_{e}-L_{\mu}$, (ii) $L_{e}-L_{\tau}$ or (iii) $L_{\mu}-L_{\tau}$.

This is an improvement by two orders on the earlier fifth force bounds in this range.

The paper
Original abstract

In the minimal standard model it is possible to gauge any one of the following global symmetries in an anomaly free way: (i)$L_{e}-L_{\mu}$, (ii) $L_{e}-L_{\tau}$ or (iii) $L_{\mu}-L_{\tau}$. If the gauge boson corresponding to (i) or (ii) is (nearly) massless then it will show up as a long range composition dependent fifth force between macroscopic objects. Such a force will also influence neutrino oscillations due to its flavour-dependence. We show that the latter effect is quite significant in spite of very strong constraints on the relevant gauge couplings from the fifth force experiments. In particular, the $L_{e}- L_{\mu,\tau}$ potential of the electrons in the Sun and the earth is shown to suppress the atmospheric neutrino $\nu_\mu \to \nu_\tau$ oscillations which have been observed at Super-Kamiokande. The Super-K data of oscillation of multi-GeV atmospheric neutrinos can be used to put an upper bound on coupling $\alpha_{e\tau}< 6.4 \times 10^{-52}$ and $\alpha_{e\mu}< 5.5 \times 10^{-52}$at 90% CL when the range of the force is the earth-sun distance. This is an improvement by two orders on the earlier fifth force bounds in this range.

Reference [ref] used solar and reactor neutrino data from KamLAND to find $g_eμ^'< 2.06 ×10^-26$ and $g_eτ^'< 1.77 ×10^-26$, at 3$σ$, assuming $θ_13 = 0^∘$.

  • For an example, the electrons inside the Sun can generate a flavor-dependent long-range potential $V_eμ/eτ$ at the Earth surface which has the following form [ref] , [equation] where $α_eμ/eτ = g^2_eμ/eτ/4π$ is the “fine structure constant" of the new abelian symmetry and $g_eμ/eτ$ is the corresponding gauge coupling.

  • At present, the global analysis of data from oscillation experiments provides some of the strongest constraints on the size of interactions affecting the neutrino flavour evolution either in the contact [ref] or the long-range [ref] regime, while the experimental bounds on the solar antineutrino flux provides strong bounds on the neutrino magnetic-moment due to its associated SFP effect (for a recent analysis see Ref. [ref] and references therein).
