Successes of SM can be mentioned such as predicting the Z and W boson gluons c charm quark t top quark and b bottom quark before they were observed by the experiments. One of those is prediction of Higgs boson recently discovered by LHC Large Hadron Collider at CERN with the 125 GeV mass. This is the last particle predicted by SM. However to this day there are much experimental data re- maining beyond prediction of SM such as Why does t top quark have the uncommon heavy mass SM predicted t quark has the approximate 10 GeV mass while the experimental result of Tevatron at Fermilab in 1995 demon- strated that t quark has the 173 GeV mass. The early universe is a quantum system therefore the number of particles equals to the one of anti-particles why the present universe only includes matter constituted by particles there is no evidence for the existence of antimatter structured by anti-particles called matter-antimatter asymmetry or baryon asymmetry. .
