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…
