How do you observe a carrier particle? How do you know that particles carry the strong force or weak force?

misogynisticfeminist said:^ hey marlon, so are you saying that virtual force carriers exist all the time, and where's there's an interaction, the virtual force carriers get the energy from the interaction to become "real"? Then after this boson is exchanged, it becomes virtual again?
marlon said:No, that is not what i meant. The vacuum is filled up with virtual particles all the time. When enough energy is available, these virtual particles can become real for a very short while.
marlon said:When for example two charged particles interact via the exchange of virtual photons, these photons are virtual during the entire interaction. Virtual in this context really means that these photons cannot be the end-product of some interaction, they are merely an intermediate stage of the interaction.

elas said:Problem is that if the vacuum has a gazzillion virtual particles (suppose each such particle is represented by one LOWEST energy quantum of a harmonic oscillator), the energy of this vacuum (the zero-point energy) becomes infinite. This will lead to difficulties with curvature of space time and this effect also predicts a very large cosmological constant
So what if ZP energy is infinite and gravity is the difference between the attractive forces of two or more bodies, how do we know what the true gravitational force of one body really is, or what the true gravitational constant is; when all we are really measuring is the quantities above an unknown base quantity.
Carrier particles are subatomic particles that carry forces between other particles. They are responsible for mediating interactions between particles, such as the electromagnetic force between charged particles.
Carrier particles are identified through experiments and theories in particle physics. Scientists use particle accelerators, such as the Large Hadron Collider, to study the behavior of particles and discover new ones. Theories, such as the Standard Model, also help to predict the existence and properties of carrier particles.
Some examples of carrier particles include the photon, which carries the electromagnetic force, the gluon, which carries the strong nuclear force, and the W and Z bosons, which carry the weak nuclear force. Gravitons, which carry the gravitational force, are also predicted but have not yet been observed.
Carrier particles interact with matter by exchanging energy and momentum. For example, the electromagnetic force is mediated by photons exchanging energy with charged particles. The weak nuclear force is mediated by W and Z bosons exchanging momentum with particles, causing radioactive decay.
Carrier particles play a crucial role in our understanding of the fundamental forces and interactions in the universe. By studying carrier particles, scientists can better understand the building blocks of matter and the underlying laws of the universe. Additionally, the discovery of new carrier particles can lead to advancements in technology and our understanding of the origins and evolution of the universe.
