Researchers at the CMS collaboration at CERN have reported the discovery of the smallest hadron in existence, the toponium.
Since its inception in 2008, the LHC at CERN has been a key player in pushing the boundaries of particle physics research. Consisting of four main experiments, the circular particle accelerator is built to push the frontiers of particle physics . The CMS collaboration, one of the four key experiments at the LHC , has announced the possible discovery of the tiniest hadron ever seen. Known as the toponium, this is a composite particle consisting of quark-antiquark pairs of the top quark.
While conducting this search, the CMS collaboration detected more top quark-antiquark pairs than expected at the minimum energy required for their creation. This led the researchers to consider the possibility that the observation seen could be a sign of the short-lived toponium. The CMS collaboration analyzed two years of data collected between 2016 and 2018 of proton-proton collisions at energies of 13 Tera electronvolts, which is the standard energy of operations at the LHC today.
