近年来，理论粒子物理学取得了巨大的进步。关于所有相互作用和粒子的理论通常具有深远的意义，例如，预测质子的衰变，并在大爆炸后的头几刻影响宇宙的发展。因此，粒子物理学现在涉及宇宙学中的问题，例如星系的形成以及观察到的物质相对于反物质的优势。这些统一理论中最雄心勃勃的理论-超弦-在罗格斯大学进行了深入研究，该大学拥有世界上最强大的粒子理论集团之一。还正在研究其他问题，例如开发在非扰动状态下研究非阿贝尔规范理论的方法，弱电重生和计算方法。对场论的理解的进步产生了与数学，统计力学和凝聚态物理有关的技术和预测现象。
Theoretical particle physics has advanced its frontiers enormously in recent years. A theory of all interactions and particles usually has far-reaching implications, for instance, predicting proton decay, and affecting the development of the universe in the first few moments after the big bang. Thus particle physics now relates to problems in cosmology, such as galaxy formation and the observed predominance of matter over anti-matter. The most ambitious of these unified theories-- superstrings--is being intensively studied at Rutgers, which has one of the strongest particle theory groups in the world. Other problems, such as developing methods to study non- abelian gauge theories in nonperturbative regimes, electroweak baryogenisis, and computational methods, are also being studied. Advances in the understanding of field theory have yielded techniques and predicted phenomena which are relevant to mathematics, statistical mechanics, and condensed matter physics.
