8021por Longo, Luigi“…However, there are several aspects in nature suggesting that SM cannot be a conclusive theory; it is, in fact, not able to explain, for example, the dark matter nature, the origin of the matter-anti-matter asymmetry in the universe, the neutrino masses and the huge difference between the Planck scale and the electroweak scale. …”

8022por Gessinger-Befurt, Paul“…Even though the Standard Model allows precise calculations of particle phenomena, it is thought to be incomplete, as certain observations like dark matter or neutrino oscillations remain unexplained. The analysis of particle collisions requires the measurement of particles produced in these collisions. …”

8023por Rastogi, Angira“…These three models target different open questions of the SM, such as the existence of vector-like leptons may provide a dark matter candidate and also account for the mass hierarchy between the different generations of matter particles in the SM, the origin and smallness of the neutrino masses can be explained by the production of heavy seesaw fermions, and scalar leptoquarks could provide an explanation for the observed b-anomalies. …”
