Electroweak Bubble Wall Friction: Analytic Results
We present an entirely analytic, leading log order determination of the friction an electroweak bubble wall feels during a first order electroweak phase transition. The friction is dominated by W bosons, and gives a wall velocity parametrically ∼ αw, and numerically small, ∼ .01 −− 0.1 depending on the Higgs mass.
متن کاملBubble wall velocity in a first order electroweak phase transition.
We calculate the velocity and thickness of a bubble wall at the electroweak phase transition in the Minimal Standard Model. We model the wall with semiclassical equations of motion and show that friction arises from the deviation of massive particle populations from thermal equilibrium. We treat these with Boltzmann equations in a fluid approximation in the background of the wall. Our analysis ...
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 کاملElectroweak Bubble Nucleation , Nonperturbatively
We present a lattice method to compute bubble nucleation rates at radiatively induced first order phase transitions, in high temperature, weakly coupled field theories, nonperturbatively. A generalization of Langer’s approach, it makes no recourse to saddle point expansions and includes completely the dynamical prefactor. We test the technique by applying it to the electroweak phase transition ...
متن کاملVelocity of Electroweak Bubble Walls
We study the velocity of bubble walls in the electroweak phase transition. For several extensions of the Standard Model, we estimate the friction and calculate the wall velocity, taking into account the hydrodynamics. We find that deflagrations are generally more likely than detonations. Nevertheless, for models with extra bosons, which give a strongly first-order phase transition, the deflagra...
