What determines the allowed time of existence for a virtual particle?

A. tiem energy uncertainty relation

B. its momentum

c. special relativity

d. decay time

A. tiem energy uncertainty relation

Explanation:

The virtual particle can be defined as a transient quantum fluctuation what exhibits some characteristics of the ordinary particle.

This concept arises in perturbation theory of quantum field theory.

It is used to describe interactions between ordinary particles.

Its existence is limited by the uncertainty principle.
