Chiral fermions in a spacetime with multiple warping

In a six-dimensional brane world model with multiple S-1/Z(2) warping, two of the 4-branes at the boundaries have coordinate-dependent brane tensions in order to implement the orbifolded boundary conditions consistently. Such brane tension is shown to be equivalent to a scalar field distribution on the brane [D. Choudhury and S. SenGupta, Phys. Rev. D 76, 064030 (2007).]. We show that in such a scenario a massless left chiral fermion on the 4-brane localizes naturally on the standard model 3-brane located at one edge of the compact manifold while the massless right chiral fermion wave function, as well as the wave functions for the massive fermion modes, peak away from this brane. This offers a mechanism of obtaining a massless chiral fermion with only one of its chiral components present in our brane.
