On symbology and differential equations of Feynman integrals from Schubert analysis
Song He, Xuhang Jiang, Jiahao Liu +1
We take the first step in generalizing the so-called "Schubert analysis", originally proposed in twistor space for four-dimensional kinematics, to the study of symbol letters and m…
Diffuse gamma-ray emission around the Rosette Nebula
Jiahao Liu, Bing Liu, Ruizhi Yang
The Rosette Nebula is a young stellar cluster and molecular cloud complex, located at the edge of the southern shell of a middle-aged SNR Monoceros Loop (G205.5+0.5). We revisited…
Cosmic ray density variations in nearby giant molecular clouds
Jiahao Liu, Bing Liu, Ruizhi Yang
In this paper, we analyzed 12 years of Fermi LAT gamma-ray data towards three nearby giant molecular clouds (GMCs), i.e., R~CrA, Chamaeleon, and Lupus. We calibrated the gas column…
The symbology of Feynman integrals from twistor geometries
Song He, Jiahao Liu, Yichao Tang +1
We study the symbology of planar Feynman integrals in dimensional regularization by considering geometric configurations in momentum twistor space corresponding to their leading si…
