Open AccessRecursive construction for expansions of tree Yang–Mills amplitudes from soft theorem
In this paper, we introduce a fundamentally different approach, based on a bottom-up methodology, for expanding tree-level Yang–Mills (YM) amplitudes into Yang–Mills-scalar (YMS) amplitudes and bi-adjoint-scal...

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 AccessBoundary contributions of on-shell recursion relations with multiple-line deformation
The on-shell recursion relation has been recognized as a powerful tool for calculating tree-level amplitudes in quantum field theory, but it does not work well when the residue of the deformed amplitude ...

Open AccessHigh-performance position-sensitive detector based on the lateral photoelectrical effect of two-dimensional materials
Two-dimensional (2D) materials such as graphene and transition-metal chalcogenides have been extensively studied because of their superior electronic and optical properties. Recently, 2D materials have shown g...

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...
