Note on scalar-graviton and scalar-photon-graviton amplitudes
Kang Zhou, Guo-Jun Zhou
In this short note, we propose an algorithm based on the expansions of amplitudes, the dimensional reduction technic and the differential operators, to calculate the tree level sca…

Transmuting off-shell CHY integrals in the double-cover framework
Kang Zhou, Guo-Jun Zhou
In this paper, by defining off-shell amplitudes as off-shell CHY integrals, and redefining the longitudinal operator, we demonstrate that the differential operators which link on-s…

Factorizations for tree amplitudes in the double-cover framework: from gravity to other theories
Kang Zhou
In this paper, we demonstrate that the factorizations for tree amplitudes in the double-cover framework, for various theories, can be generated from the gravity amplitude in the do…
