Spacelike-Collinear Scattering by the Method of Regions
Wen Chen, Einan Gardi, Rourou Ma +3
We study the spacelike-collinear limit of gauge-theory scattering amplitudes using the Method of Regions. The corresponding splitting amplitude violates strict collinear factorisat…
Progress on the soft anomalous dimension in QCD
Einan Gardi, Zehao Zhu
We review the state-of-the-art knowledge of IR singularities in multileg QCD amplitudes, identifying the key reasons for the remarkable simplicity of the soft anomalous dimension.…
Infrared singularities of multileg amplitudes with a massive particle at three loops
Einan Gardi, Zehao Zhu
We determine the complete three-loop QCD soft anomalous dimension for multileg amplitudes involving a single massive coloured particle and any number of massless ones. This is achi…
Computing the soft anomalous dimension with massless particles using the method of regions
Einan Gardi, Zehao Zhu
It is well known that soft singularities of massless amplitudes are significantly simpler than those of massive ones. However, the computation of the soft anomalous dimension (AD)…
Extracting a model quark propagator's spectral density
Zehao Zhu, Khépani Raya, Lei Chang
We propose a practical procedure to extrapolate the space-like quark propagator onto the complex plane, which follows the Schlessinger Point Method and the spectral representation…
