Antimatter antarctica4/6/2023 ![]() ![]() For example, a positron with positive charge has the same mass as an electron an antiproton with negative charge has the same mass as a proton. For every familiar particle type we find a matching antiparticle with opposite charge, but exactly the same mass. How did matter gain the upper hand over antimatter?Īntimatter exists! We routinely make it in laboratories. We estimate the molecular annihilation lifetimes in their s states.« less We find that matter-antimatter molecules with constituents (m), which satisfy the stability condition. We examine the stability of matter-antimatter molecules by reducing the four-body problem into a simpler two-body problem with residual interactions. Data also cover annihilation interaction with the matter-antimatter boundary to produce the essential fluid motion known as coalesence.ĭOE Office of Scientific and Technical Information (OSTI.GOV) ![]() Several theories and models are examined, with particular emphasis on nucleon-antinucleon interactions at intermediate energies. As a starting point, an attempt was made to understand the origin of matter as being essentially analogous to the origin of backgound thermal radiation. The possible existence of antimatter on a large scale in the universe is evaluated. Coalescence and annihilation rates are discussed. These particles together with secondary particles which they put into motion by collisions, carry their momentum to the matter or antimatter fluid. This mechanism involves annihilation production of along the boundary of matter-antimatter, high energy photons, electrons, and positrons. Particular attention was given to coalesence. Mechanisms responsible for the orgin and separation of matter and antimatter in the universe are discussed. ![]()
