How to choose a good rational basis for elliptic Feynman integrals?
Ekta Chaubey, Vasily Sotnikov
Representing multi-loop scattering amplitudes as linear combinations of multivalued transcendental functions with process-dependent rational coefficients has long been understood t…
Light-by-light scattering: asymptotic expansions, Coulomb resummation and NLO corrections
Ajjath A H, Ekta Chaubey, Hua-Sheng Shao
Light-by-light (LbL) scattering is one of the earliest predictions of quantum electrodynamics (QED). Interest in this process has been renewed following its experimental observatio…
Estimating power corrections for the Drell-Yan Process
Ekta Chaubey, Pooja Mukherjee
We study power corrections in the Drell-Yan (DY) process using state-of-the-art predictions for both neutral and charged current production. For both types of DY processes, we acco…
A comprehensive analysis of Drell-Yan production uncertainties and mass effects at moderate and low dilepton masses
Ekta Chaubey, Claude Duhr, Rhorry Gauld +1
We present a thorough investigation of the sources of uncertainties to the Drell-Yan production using state-of-the-art predictions for both neutral and charged current channels, fo…
Two-loop helicity amplitudes for diphoton production with massive quark loop
Taushif Ahmed, Amlan Chakraborty, Ekta Chaubey +1
We compute two-loop helicity amplitudes in QCD for diphoton production through quark- and gluon-initiated channels, accounting for a massive internal quark loop by keeping its full…
Two-loop massive QCD and QED helicity amplitudes for light-by-light scattering
Ajjath A H, Ekta Chaubey, Hua-Sheng Shao
We present the analytic and compact two-loop helicity amplitudes for QCD and QED corrections to the light-by-light scattering process with massive internal fermions. We express the…
