We apply quantum integration to elementary particle-physics processes. In particular, we look at scattering processes such as e+e??qq¯ and e+e??qq¯?W. The corresponding probability distributions can be first appropriately loaded on a computer using either Generative Adversarial Networks or an exact method. are then integrated the method of Quantum Amplitude Estimation which shows quadratic spee...

HEN A STRANGER, hearing that I am a physicist, asks me in what area of physics I work, I generally reply that I work on the theory of elementary particles. Giving this answer always makes me nervous. Suppose that the stranger should ask, “What is an elementary particle?” I would have to admit that no one really knows. Let me declare first of all that there is no difficulty in saying what is mea...

J.M.G. Fell and other authors have asserted that an elementary particle has only one ‘intrinsic’ state. I will argue that this claim is not consistent with the mathematical structures and objects used to represent an elementary particle in relativistic quantum theory.
