The massive Dirac field on a rotating black hole spacetime: Angular solutions

Understand

The massive Dirac equation on a Kerr-Newman background may be solved by the method of separation of variables.

• The radial and angular equations are coupled via an angular eigenvalue, which is determined from the Chandrasekhar-Page (CP) equation.
• Obtaining accurate angular eigenvalues is a key step in studying scattering, absorption and emission of the fermionic field.
• Here we introduce a new method for finding solutions of the CP equation.
