“…The simulated JUNO IBD-like spectrum for one year of statistics is shown in Figure 5 (Right), with 400 expected geoneutrino events shown in red. JUNO will reach the precision of the current Borexino [19] and KamLAND [20] measurements in about one year [10,21]. Additionally, JUNO will be able to measure the U/Th ratio, a parameter that will provide insights about the Earth's formation processes.…”

“…If we talk about the presence of light elements inside Earth, we don't know how much H 2 O is present in the mantle and how much H is present in the core [15,20,21]. The precise measurement of radioactive power produced in the mantle and core is important to understand the thermal dynamics inside Earth [22][23][24][25].…”

Atmospheric neutrinos provide a unique avenue to explore the internal structure of Earth based on weak interactions, which is complementary to seismic studies and gravitational measurements. In this work, we demonstrate that the atmospheric neutrino oscillations in the presence of Earth matter can serve as an important tool to locate the core-mantle boundary (CMB). An atmospheric neutrino detector like the proposed 50 kt magnetized ICAL at INO can observe the core-passing neutrinos efficiently. These neutrinos would have experienced the MSW resonance and the parametric or neutrino oscillation length resonance. The net effect of these resonances on neutrino flavor conversions depends upon the location of CMB and the density jump at that radius. We quantify the capability of ICAL to measure the location of CMB in the context of multiple three-layered models of Earth. For the model where the density and the radius of core are kept flexible while the mass and radius of Earth as well as the densities of outer and inner mantle are fixed, ICAL can determine the location of CMB with a 1σ precision of about 250 km with an exposure of 1000 kt yr. With the 81-layered PREM profile, this 1σ precision would be about 350 km. The charge identification capability of ICAL plays an important role in achieving this precision.

“…With the inverse beta decay threshold of 1.8 MeV, JUNO can detect geoneutrinos from the decay chains of 9. For comparison, the current flux precision is 17% by Borexino with 8.9 years exposure (2020) [4], and 15% by KamLAND with 14.3 years exposure (2022) [5].…”

Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose 20 kton liquid scintillator detector being constructed in southern China. Its primary goal is the determination of the neutrino mass ordering using neutrinos emitted from the Taishan and Yangjiang nuclear power plants about 52.5 km away and neutrinos produced in the atmosphere, which will play a complementary role. In addition, oscillation parameters Δ𝑚 2 31 , Δ𝑚 2 21 , and 𝜃 12 can be measured to a sub-percent level using the reactor neutrinos. Due to its large detector mass, JUNO can also provide a high statistics measurement on geo-neutrinos. This talk presents the current status of JUNO, as well as the physics potentials of measuring neutrinos from the reactors, atmosphere and Earth.
