Charge asymmetry from CP-violating fermion scattering off bubble walls during the electroweak phase transition
We compute the net electric current generated during a first order electroweak phase transition when fermions transit from the false to the true vacuum. This current is generated by the CPviolating fermion interaction with the Higgs during the phase transition and is quantified in terms of a CP-violating phase in the bubble wall separating the symmetric from the symmetry-broken phases. We comme...
متن کاملScattering in the presence of electroweak phase transition bubble walls.
We investigate the motion of fermions in the presence of an electroweak phase transition bubble wall. We derive and solve the Dirac equation for such fermions, and compute the transmission and reflection coefficients for fermions traveling from the symmetric to the asymmetric phases separated by the domain wall.

متن کاملFermion scattering off a CP-violating electroweak bubble wall.
A general prescription to solve the Dirac equation in the presence of CPviolating electroweak bubble wall is presented. The profile of the bubble wall is not specified except that the wall height is m0 and zero deep in the brokenand the symmetric-phase regions, respectively, where m0 is a fermion mass given by the Higgs-vacuum-expectation value and the Yukawa coupling. The CP-violating effects ...
متن کاملExact solution for charged - particle propagation during a first - order electroweak phase transition with hypermagnetic fields
We obtain the exact solution of the Klein-Gordon equation describing the propagation of a particle in two regions of different constant magnetic field, separated by an infinite plane wall. The continuity of the wave function and of its derivative at the interface is satisfied when including evanescent-wave terms. We analyze solutions on truncated spaces and compare them with previously obtained...
متن کاملInfluence of the magnetic field on the fermion scattering off bubble and kink walls
We investigate the scattering of fermions off domain walls at the electroweak phase transition in presence of a magnetic field. We consider both the bubble wall and the kink domain wall. We derive and solve the Dirac equation for fermions with momentum perpendicular to the walls, and compute the transmission and reflection coefficients. In the case of kink domain wall, we briefly discuss the ze...
