Electroweak phase transitions in a $U(1{)}_D$ extension of the standard model with dimension-six operators: Gravitational waves and LHC signatures

Arka Bhattacharyya, Sanjoy Biswas, Saurabh Niyogi

We investigate the possibility of realizing strong first-order electroweak phase transition (SFOEWPT) in an effective field theory framework where the Standard Model is extended wi…
