Theoretical research in elementary particle physics will emphasize the application of non-perturbative quantum field theory methods to a variety of problems which cannot be solved by treating some part of the physics as a perturbation. One of these problems is the possible non-conservation of baryon (nucleon) number at high energies due to quantum-mechanical tunneling. A second is the completion of a field theory of strings. Baryon number non-conservation at high energies would lead to extremely interesting collisions at the Superconducting Super Collider, and a field theory of strings would be an important step in the evolution of a string theory of the fundamental forces.

基本粒子物理学的理论研究将强调应用非微扰量子场论方法来解决各种问题，这些问题不能通过将物理的某些部分视为微扰来解决。其中一个问题是高能重子（核子）数可能因量子力学隧穿而不守恒。第二个是完成弦的场论。高能重子数不守恒将导致超导超级对撞机中非常有趣的碰撞，而弦的场论将是基本力的弦理论发展的重要一步。
