      abstract     = {We explore the real-singlet extension of the Standard Model
                      without a Z2 symmetry (RxSM) as a framework to address the
                      baryon asymmetry of the Universe and investigate
                      modifications to the Higgs potential. First, we identify
                      regions of parameter space that allow a Strong First-Order
                      Electroweak Phase Transition (SFOEWPT) using the public
                      tools BSMPT, CosmoTransitions, and TransitionListener, while
                      incorporating relevant theoretical constraints as well as
                      experimental bounds through HiggsTools. Additionally, we
                      calculate the stochastic gravitational wave background and
                      assess its potential observability at LISA. Next, we
                      determine the one-loop corrections to the trilinear Higgs
                      couplings involved in di-Higgs production (hhh) and (hhH)
                      using the public code anyH3. Finally, we evaluate the
                      di-Higgs production cross section at the (HL-)LHC within the
                      regions of the RxSM parameter space that permit an SFOEWPT,
                      taking into account the one-loop corrections to the
                      trilinear Higgs couplings. This result is compared with
                      those obtained in the SM and in the RxSM at tree level,
                      highlighting the significant impact of loop corrections on
                      the trilinear couplings.},
