我们描述了四维中涉及无质量粒子的一组独立纯平面主积分的构造，该组包含双环下所有最大权重贡献。在此基底下，每个与红外发散相关的独立区域都由特定主积分单独匹配，其余所有主积分在四维中显然是有限的。
英文摘要
We describe the construction of a spanning set of individually pure, planar master integrals involving massless particles in four dimensions which include all maximal-weight contributions at two loops. In this basis, every independent region associated with infrared divergence is individually matched by specific masters, with all other masters being manifestly finite in four dimensions.
