On the amplitudes at two loop in QCD

Taushif Ahmed

Through this article, we show that the amplitudes for the in the presence of bottom-Higgs Yukawa coupling can be constructed, up to a few anomalous diagra…

A pitfall in applying non-anticommuting in amplitudes

Taushif Ahmed

In computing the two-loop QCD corrections to a class of Feynman diagrams for the process in Higgs effective field theory, we discover a striking phen…

Renormalization of the flavor-singlet axial-vector current and its anomaly in dimensional regularization

Taushif Ahmed, Long Chen, Michał Czakon

The renormalization constant of the flavor-singlet axial-vector current with a non-anticommuting in dimensional regularization is determined to order in QCD wit…

Soft-virtual correction and threshold resummation for -colorless particles to fourth order in QCD: Part I

Taushif Ahmed, Ajjath A. H., Goutam Das +3

We present the general form of a universal soft-collinear distribution operator to compute the soft-virtual cross-section to next-to-next-to-next-to-next-to-leading order (NLO)…

Rapidity distribution at soft-virtual and beyond for n-colorless particles to NLO in QCD

Taushif Ahmed, Ajjath A. H., Pooja Mukherjee +2

We present a systematic framework to study the threshold contributions of the differential rapidity distribution for the production of any number of colorless particles in the hadr…

Polarized Higgs amplitudes at two loops in QCD: the interplay between vector and axial vector form factors and a pitfall in applying a non-anticommuting

Taushif Ahmed, Werner Bernreuther, Long Chen +1

We consider QCD corrections to two loops for the polarized amplitudes of Higgs boson. First we show how the polarized amplitudes of a…
