标题： Scale-anomaly-induced confining pressure within hadrons

摘要： 量子色动力学尺度异常对强子内部压力分布的影响是基于能量-动量张量的迹-迹零分解来研究的。 利用最近的与模型无关的引力形式因子结果作为输入，在瞬时形式和光锥形式下分析了介子和核子的压力分布。 发现在所有情况下，尺度异常主要产生束缚压力。 这一结果表明该现象是一个普遍特征，与模型、强子类型和形式的选择无关。 显示英文摘要

摘要： The effect of the QCD scale anomaly on the internal pressure distribution of hadrons is studied based on the trace-traceless decomposition of the energy-momentum tensor. Using recent model-independent results of gravitational form factors as input, the pressure distributions of both pions and nucleons are analyzed in the instant form and the light-front form. It is found that, in all cases, the scale anomaly dominantly generates the confining pressure. This result suggests that the phenomenon is a universal feature, independent of models, types of hadrons, and the choice of form.
