![]() ![]() ![]() The discovery of a mechanism for baryogenesis or CP-violation would have major implications for our understanding of the universe, and could also have implications for other areas of physics such as the search for dark matter.In order to investigate the origin of matter-antimatter asymmetry in the Universe, we adopt a theoretical framework where the standard model emerges as a Poincaré invariant field theory localized at a domain-antidomain wall (DW-aDW) brane pair of a theory which lives on a higher dimensional bulk. The current leading explanations include baryogenesis, CP-violation and Leptogenesis. In summary, There is still a lot of research and studies going on to understand the reason behind the existence of more matter than antimatter in the universe. The discovery of a mechanism for baryogenesis or CP-violation would have major implications for our understanding of the universe, and could also have implications for other areas of physics such as the search for dark matter. ![]() The search for a definitive explanation for the matter-antimatter asymmetry continues to be an active area of research in physics and cosmology. These decays would have created a surplus of matter over antimatter, leading to the observed asymmetry in the universe. Theories beyond the Standard Model of physics, such as supersymmetry and grand unification theories, also predict the existence of baryon number violation and CP-violation, providing further support for these explanations of the matter-antimatter asymmetry.Įxperiments such as the BaBar experiment at SLAC National Accelerator Laboratory and the Belle experiment at KEK in Japan have been searching for evidence of CP-violation in the behavior of particles called B-mesons, which could provide further insight into the matter-antimatter asymmetry.Īnother possible explanation is called leptogenesis, which posits that the matter-antimatter asymmetry was generated through the decays of heavy, short-lived particles called leptons. However, if there is a slight difference in the behavior of matter and antimatter, known as CP-violation, this could have led to a slight imbalance in their production, resulting in more matter than antimatter. In the early universe, matter and antimatter would have been in thermal equilibrium, meaning that they were produced and destroyed in equal amounts. The violation of baryon number would have allowed for the creation of more matter than antimatter, leading to the observed asymmetry.Īnother explanation for the matter-antimatter asymmetry is the presence of CP-violation, or violation of a symmetry known as charge-parity symmetry. Baryon number is a property of particles that distinguishes between matter and antimatter. Baryogenesis proposes that during the early universe, a small imbalance of matter over antimatter was created through a process called baryon number violation. One possible explanation for the matter-antimatter asymmetry is known as baryogenesis. While the laws of physics do not distinguish between matter and antimatter, the observed asymmetry in their abundance is a major puzzle. The question of why there is more matter than antimatter in the universe is a fundamental one in physics and cosmology. ![]()
