Open AccessAn explicit expression of generating function for one-loop tensor reduction
This work introduces an explicit expression for the generating function for the reduction of an n-gon to an (n – k)-gon. A novel recursive relation of generating function is formulated based on Feynman Parametriz...

Open AccessReduction with degenerate Gram matrix for one-loop integrals
An improved PV-reduction (Passarino-Veltman) method for one-loop integrals with auxiliary vector R has been proposed in [1, 2]. It has also been shown that the new method is a self-completed method in [3]. Analyt...

Open AccessOne-loop CHY-integrand of bi-adjoint scalar theory
In this paper, the one-loop CHY-integrands of bi-adjoint scalar theory has been reinvestigated. Differing from previous constructions, we have explicitly removed contributions from tadpole and massless bubbles...
