Query: Fermion localization and resonances on two-field thick branes   We consider $(4,1)$-dimensional branes constructed with two scalar fields
$\phi$ and $\chi$ coupled to a Dirac spinor field by means of a general Yukawa
coupling. The equation of motion for the coefficients of the chiral
decomposition of the spinor in curved spacetime leads to a Sch\"odinger-like
equation whose solutions allow to obtain the masses of the fermionic modes. The
simplest Yukawa coupling $\bar\Psi\phi\chi\Psi$ is considered for the Bloch
brane model and fermion localization is studied. We found resonances for both
chiralities and related their appearance to branes with internal structure.
