Description

Recently, it has been discussed that a possibility of primordial black holes is generated from the first-order phase transition at high or low temperatures. We consider the primordial black hole production during first-order electroweak phase transition. In this talk, we discuss the comprehensive test of the model with strongly first-order electroweak phase transition at the measurement of hhh coupling at ILC, the primordial black hole and gravitational wave from first-order electroweak phase transition.
