IBP reduction coefficients made simple
Janko Boehm, Marcel Wittmann, Zihao Wu +2
We present an efficient method to shorten the analytic integration-by-parts (IBP) reduction coefficients of multi-loop Feynman integrals. For our approach, we develop an improved v…

On D-brane interaction & its related properties
Qiang Jia, J. X. Lu, Zihao Wu +1
We compute the closed-string cylinder amplitude between one Dp brane and the other Dp brane, placed parallel at a separation, with each carrying a general constant worldvol…
