What are the properties and interactions of antineutrinos in particle physics?

Antineutrinos are subatomic particles that have no electric charge and very little mass. They interact with other particles through the weak nuclear force, which is responsible for processes like radioactive decay. Antineutrinos can change into other types of neutrinos through a process called neutrino oscillation. They are important in understanding the behavior of matter at the smallest scales in particle physics.
