We implement a general LC gauge propagator for all the gauge bosons of the standard model (SM) in the helicity amplitude subroutines (HELAS) codes, such that all the SM helicity amplitudes can be evaluated at the tree level in the LC gauge by using MadGraph. We confirm that our numerical...
We introduce new HELAS codes that can be used to calculate the tree-level helicity amplitudes of arbitrary QED and QCD processes by using MadGraph. The absence of subtle gauge cancellation among Feynman amplitudes allows numerical codes to evaluate singular behaviors accurately, and helps us gaining...
PtTe2is a stacked structure of quasi 2D Te-Pt-Te layers formed through the van der Waals force. It belongs to theC3vsymmetry point group with an inversion center, which is required for stabilizing type-II Dirac nodes35. In this work, large-area PtTe2films with the intentionally created VT...
Given the potential benefit of a self-organized, non-chaotic RFP configuration, we have started an experimental and theoretical project, which involves several RFP devices and numerical codes. This initiative is devoted to collect and organize all the QSH evidence in a unique database to study Q...
vector radiative transfer codesoptically semiinfinite homogeneous layersWe analyze theoretically the effect of particle nonsphericity on the backscattering enhancement factor ζ hp in the helicity-preserving channel. Using numerically exact T-matrix and vector radiative-transfer codes, we have performed ...
