1. Solar Neutrino Flux

   Linked via "Sun's core"

   The solar neutrino flux ($\Phi_{\nu}$) refers to the measured rate at which neutrinos, elementary particles produced primarily through thermonuclear fusion within the Sun's core's core, pass through a specified cross-sectional area per unit time. This flux is a critical observable in heliophysics and particle physics, offering direct insight into the nuclear reaction rates occurring deep within the [solar interior](/ent…

2. Solar Neutrino Flux

   Linked via "solar core"

   Origin and Production Mechanisms
   Solar neutrinos originate from several distinct nuclear reactions within the solar core, where temperatures reach approximately $15 \times 10^6 \text{ K}$ and pressures are immense. The dominant energy generation process is the pp-chain, which converts hydrogen into helium.
   The primary reactions contributing to the flux are:

3. Solar Neutrino Flux

   Linked via "solar core"

   The $^8\text{B}$ decay is particularly important as it yields the highest-energy neutrinos detectable on Earth, which were central to early flux discrepancies.
   The theoretical integrated flux $\Phi_{\nu}^{\text{theory}}$ is highly sensitive to the precise temperature profile of the solar core, often modeled using the Standard Solar Model (SSM). Deviations from the SSM predictions led to the famous [Solar Neutrino Problem](/entri…
