Neutrino Propagation in Matter

Figure 6

Resonance enhancement of neutrino oscillations in matter with constant density. Shown is the dependence of the transition probability 𝜈_𝑒→𝜈_𝜇 on energy for sin²𝜃₁₃=0.0241 for three different sizes of layers: 𝐿=3𝑙_𝑚(𝐸_𝑅)/2, 𝑙_𝑚(𝐸_𝑅)/2, and 𝑙_𝑚(𝐸_𝑅)/6. The shaded area shows the resonance envelope: sin²2𝜃_𝑚(𝐸).
