  We discuss the impact of a swifter cosmological expansion induced by modified
cosmological history of the universe on scenarios realising electroweak
baryogenesis. We detail the possible experimental bounds one can place on such
cosmological modification and show how the detection capabilities of particle
models are modified within these bounds. On the particle physics side we focus
on the Standard Model supplemented by a dimension six operator which directly
modifies the Higgs potential. We show that due to the cosmological
modification, electroweak baryogenesis in this model can be realized, with the
modification of the triple Higgs coupling below HL-LHC sensitivity.
