Super-Leading Logarithms in Top-Quark Pair Production at Hadron Colliders
Upalaparna Banerjee, Romy Grünhofer, Matthias König +3
To date, the appearance and resummation of "super-leading" logarithms in hadron-hadron collisions has been studied only for massless parton states. We extend the formalism to inclu…
Resurrecting the LHC discovery potential in the extended Type-II Seesaw Model
Upalaparna Banerjee, Christoph Englert, Wrishik Naskar
The juxtaposition of the precision of lepton flavour measurements and the limited energy range of the Large Hadron Collider (LHC) to discover dynamical degrees of freedom linked to…
Feasibility of ultrarelativistic bubbles in SMEFT
Upalaparna Banerjee, Sabyasachi Chakraborty, Suraj Prakash +1
A first order electroweak phase transition probes physics beyond the Standard Model on multiple frontiers and therefore is of immense interest for theoretical exploration. We condu…
EFT, decoupling, Higgs boson mixing, and higher dimensional operators
Upalaparna Banerjee, Joydeep Chakrabortty, Christoph Englert +3
The effective field theory (EFT) framework is a precise approximation procedure when the inherent assumptions of a large-scale separation between the Standard Model (SM) and new in…
