Investigation on the origin, evolution and structure of strongly interacting (hadronic) matter requires both experimental and theoretical effort. Chiral Perturbation Theory has been tremendously successful in describing low-energy hadronic interactions in the non-perturbative regime of Quantum Chromodynamics. The main purpose of our theoretical research is to take advantage of the new symbolic computing methods and to bring subatomic physics computations to the next level by developing a computational model with a consistent power counting scheme within relativistic Chiral Perturbation Theory.

强相互作用（强子）物质的起源、演化和结构的研究需要实验和理论两方面的努力。手性微扰理论在描述量子色动力学的非微扰状态下的低能强子相互作用方面取得了巨大的成功。我们理论研究的主要目的是利用新的符号计算方法，并通过在相对论性手性微扰理论中开发具有一致功率计数方案的计算模型，将亚原子物理计算提升到一个新的水平。
