| contents | In this paper we investigate the behaviour of massless fermions in the black string spacetime by computing the eigenvalues and eigenfunctions of the Weyl equations. These solutions allowed us to study the behaviour of such massless fermions in terms of the cosmological constant, the black string's mass and the radial distance of the particle from the black string. The solutions, written in terms of Parabolic Cylinder functions and Laguerre polynomials, were obtained for a particle far from the black string and around the horizon event. For the particle around the event horizon, for all configuration of parameters, the energy eigenvalues are complex-valued, indicating QNM similarly to the case of spherical black holes. For the particle far from the black string, the energies derived from the Weyl equation set up conditions on the parameters in order to keep the energy as a real valued parameter. |
