Three-loop helicity amplitudes for photon+jet production
Piotr Bargiela, Amlan Chakraborty, Giulio Gambuti
We present three-loop helicity amplitudes for the production of a single photon in association with one jet in Quantum Chromodynamics, a final state which provides a standard candl…
Three-Loop Four-Point Scattering Amplitudes in Massless Gauge Theories
Amlan Chakraborty, Giulio Gambuti
We present novel techniques for the computation of three-loop four-parton scattering amplitudes in full color, non-planar gauge theories. We elaborate on how the analytic results f…
Three-loop helicity amplitudes for quark-gluon scattering in QCD
Fabrizio Caola, Amlan Chakraborty, Giulio Gambuti +2
We compute the three-loop helicity amplitudes for and its crossed partonic channels, in massless QCD. Our analytical results provide a non-trivial check of the co…
The vertex at four loops and hard matching coefficients in SCET for various currents
Amlan Chakraborty, Tobias Huber, Roman N. Lee +5
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…
