Abstract On-shell kinematics for gluon scattering can be parametrized with points on the celestial sphere; in the limit where these points collide. it is known that tree-level gluon scattering amplitudes exhibit an operator product expansion (OPE)-like structure. While it is possible to obtain singular contributions to this celestial OPE. getting regular contributions from both holomo... https://cosmicclothingers.shop/product-category/hoodie/
