Domain Wall Splitting in Extra Dimension

Figure 3

The scalar field (3.2) versus the extra dimensional coordinate which we designate by 𝑤. The mass parameter is parameterized by 𝑎=1−𝜀. The solid curve corresponds to the case where 𝜀=10⁻⁸, the dashed curve is for 𝜀=10⁻¹⁰, and finally the dotted curve is for 𝜀=10⁻¹².
