String amplitudes from field-theory amplitudes and vice versa
Song He, Fei Teng, Yong Zhang
We present an integration-by-parts reduction of any massless tree-level string correlator to an equivalence class of logarithmic functions, which can be used to define a field-theo…
Generalized Calabi-Gray Geometry and Heterotic Superstrings
Teng Fei
We give an expository about compactification of heteorotic superstrings with torsion on generalized Calabi-Gray manifolds.
Parabolic Dimensional Reductions of 11D Supergravity
Teng Fei, Bin Guo, Duong H. Phong
Ansatze are constructed under which the solutions of 11D supergravity must be stationary points of a parabolic flow on a Riemannian manifold . This parabolic flow turns o…
Unraveling conformal gravity amplitudes
Henrik Johansson, Gustav Mogull, Fei Teng
Conformal supergravity amplitudes are obtained from the double-copy construction using gauge-theory amplitudes, and compared to direct calculations starting from conformal supergra…
Permutation in the CHY-Formulation
Rijun Huang, Fei Teng, Bo Feng
The CHY-integrand of bi-adjoint cubic scalar theory is a product of two PT-factors. This pair of PT-factors can be interpreted as defining a permutation. We introduce the cycle rep…
