Abstract
We have investigated the possibility of generating baryon inhomogeneities in the quark-gluon plasma phase in the early universe due to CP violating scattering of quarks and anti-quarks from moving Z(3) domain walls. CP violation, here, is spontaneous in nature, and arises from the non-trivial profile of the background gauge field between different Z(3) vacua. We have calculated the spatial variation of the background gauge field across the Z(3) interface from the profile of the Polyakov loop L(x) for the Z(3) interface and determined the reflection of quarks and anti-quarks using the Dirac equation. Our results have shown that the reflection coefficients of quarks and anti-quarks can differ by a large amount. We have discussed the implications of this for baryon inhomogeneity generation from collapsing large Z(3) walls.
