Elektrondipólusú

Elektrondipólusú, also known as electron dipole moment (EDM), is a fundamental property of particles that describes the separation of positive and negative charges within the particle. In the context of elementary particles, it is a measure of the asymmetry between the distribution of positive and negative charges within the particle. The EDM is a crucial parameter in the study of parity (P) and time-reversal (T) symmetries, as well as charge-parity (CP) violation, which are fundamental concepts in particle physics.

The EDM of a particle is typically very small, often on the order of 10^-29 to 10^-30 electron-centimeters (e·cm). The search for a non-zero EDM is an active area of research, as it could provide evidence for new physics beyond the Standard Model of particle physics. The Standard Model predicts that the EDM of elementary particles should be extremely small, making it a sensitive probe for new interactions or particles.

Experimental searches for the EDM of particles such as the electron, neutron, and proton have been conducted using various techniques, including atomic and molecular spectroscopy, neutron interferometry, and storage ring experiments. These experiments aim to measure any tiny asymmetry in the distribution of charges within the particles, which could indicate the presence of new physics.

The study of EDMs is not only important for understanding the fundamental properties of particles but also for addressing some of the most pressing questions in physics, such as the matter-antimatter asymmetry in the universe and the nature of dark matter. By searching for a non-zero EDM, scientists hope to gain insights into the underlying principles of the universe and potentially uncover new phenomena that could revolutionize our understanding of the physical world.
