The und.rlying phys.cs.of QCd.phas. trans.tion in the early Univers. remains.largely unknown d.e to its.s.rong-coupling nature d.ring the quark-gluon plas.a/had.on gas.trans.tion, yet a holographic mod.l has.been propos.d.to quantitatively fit the lattice QCd.d.ta while with its.d.ration of the firs.-ord.r phas. trans.tion(FoPT) left und.termined. At s.ecific baryon chemical potential, the firs.-ord.r QCd.phas. trans.tion agrees.with the obs.rvational cons.raint of baryon as.mmetry. It, therefore, provid.s.a s.enario for phas. trans.tion gravitational waves.GWs. within the s.and.rd.mod.l of particle phys.cs.
