Tömegpár
Tömegpár is a Hungarian term that translates to "mass pair" in English. It is most commonly encountered in the context of physics, specifically in particle physics and cosmology. In particle physics, a tömegpár refers to a pair of particles that have identical mass but opposite charges or other quantum numbers. For example, an electron and a positron form a tömegpár as they have the same mass but opposite electric charges. These pairs can be created from energy, such as in high-energy collisions, and can annihilate each other, converting their mass back into energy.
In cosmology, the concept of tömegpár can also be related to the creation of matter and antimatter
