About a possibility of measuring the central temperature of the Sun through the regeneration of the 7Be neutrinos in the Earth

The solar neutrino's 7Be line (Eν 0.862 MeV) has a width of order the temperature in the center of the Sun (∼ 1 keV).The regeneration of neutrinos from remote structures of the Earth is suppressed due to the averaging of the effect over the width of the 7Be line (oscillation dying effect). We d...

Summary:The solar neutrino's 7Be line (Eν 0.862 MeV) has a width of order the temperature in the center of the Sun (∼ 1 keV).The regeneration of neutrinos from remote structures of the Earth is suppressed due to the averaging of the effect over the width of the 7Be line (oscillation dying effect). We discuss a possibility of measuring the width of the beryllium line at large liquid scintillator detector (LENA) by measuring the electron neutrino flux at different nadir angles of neutrino trajectories.
