Towards mixed QCDxEW corrections to the charged-current Drell-Yan process with leptonic decay at high transverse masses
Christian Biello, Amlan Chakraborty, Giulio Gambuti +2
The Drell-Yan process is a key precision benchmark at the Large Hadron Collider and a sensitive probe of SM and SMEFT effects. Fully exploiting future LHC data requires percent-lev…
Light-by-light scattering at three loops in massless QCD and QED: amplitudes and cross sections
Piotr Bargiela, Amlan Chakraborty, Giulio Gambuti +1
We present the calculation of three-loop massless QCD and QED helicity amplitudes for light-by-light scattering. We make use of Lorentz tensor decomposition in the 't Hooft-Veltman…
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…
Three-loop helicity amplitudes for photon+jet production

We compute the four-loop corrections to the Higgs-bottom vertex within massless QCD and present analytic results for all color structures. The infrared poles of the renormalized fo…
Formation and Abundance of Late Forming Primordial Black Holes as Dark Matter
Amlan Chakraborty, Prolay K Chanda, Kanhaiya Lal Pandey +1
We propose a novel mechanism where Primordial Black Hole (PBH) dark matter is formed much later in the history of the universe between the epoch of Big Bang Nucleosynthesis (BBN) a…
