Physics:Quantum virtual particle
From HandWiki Test
A quantum virtual particle is an internal element of a perturbative quantum-field calculation rather than a directly observed free particle. Virtual particles represent intermediate contributions to amplitudes and should not be confused with ordinary detector particles.[1][2]
Conceptual role
This topic lies at the boundary between quantum field theory, relativity, cosmology, and the foundations of measurement. It clarifies what is meant by fields, particles, vacuum, and geometry.[3]
Open questions
The main unresolved issues concern how geometry, vacuum structure, horizons, and quantum states behave when gravitational and quantum effects are simultaneously important.[4]
