Suppose there's an interaction AB -> CD, that goes via a virtual W boson, my question is, will the virtual boson leaves a track in the detector even though it's virtual ?
neu said:No is the short answer to your question.
Think about what virtual means. A particle is virtual i.e "off mass shell" (violating energy conservation) for a time permitted by the uncertainty principle. Hence by definition it's impossible to "resolve" a virtual particle. Hence the name virtual.
Virtual particles are particles that are not directly observable and do not exist in a measurable form in the physical world. They are considered to be temporary fluctuations in energy that arise due to the uncertainty principle in quantum mechanics.
Virtual particles interact with each other through the exchange of virtual bosons. These virtual bosons, also known as force carriers, are responsible for mediating the fundamental forces in nature, such as electromagnetism and the strong and weak nuclear forces.
No, virtual bosons do not leave a track when they interact. This is because they are not directly observable and do not have a measurable physical presence. Their effects can only be detected through their interactions with other particles.
Scientists study virtual particle interaction through mathematical equations and models based on quantum field theory. They also use particle colliders, such as the Large Hadron Collider, to create and observe the effects of virtual particles.
No, virtual particle interactions cannot be observed in everyday life. They only occur at the subatomic level and have very short lifetimes. Their effects can only be observed through sophisticated experiments and calculations.
