positroniksi
Positroniksi is a speculative particle physics concept that describes a composite particle made up of two positrons. While individual positrons are well-established as the antiparticles of electrons, a bound state of two positrons has not been experimentally observed and is generally considered unlikely to be stable due to the strong electrostatic repulsion between the two positively charged particles. Theoretical investigations into such a system, often termed a "dimeson" or "positronium molecule," explore the conditions under which such a state might momentarily exist or if it could form under extreme energy conditions. The primary challenge is overcoming the Coulomb repulsion. Even with quantum mechanical effects and potential relativistic considerations, the binding energy required to overcome this repulsion would need to be significant. If such a particle were to exist, it would have unique decay modes and interactions, differing from those of single positrons or electron-positron pairs. Current experimental efforts in particle physics focus on more conventional particles and interactions, and the existence of positroniksi remains a theoretical curiosity rather than an active area of experimental research.
