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…

Renormalization of Scalar and Fermion Interacting Field Theory for Arbitrary Loop: Heat-Kernel Approach

Upalaparna Banerjee, Joydeep Chakrabortty, Kaanapuli Ramkumar

We outline a proposal, based on the Heat-Kernel method, to compute 1PI effective action up to any loop order for quantum field theory with scalar and fermion fields. We algebraical…

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…

One-loop Effective Action up to any Mass-dimension for Non-degenerate Scalars and Fermions including Light-Heavy Mixing

Upalaparna Banerjee, Joydeep Chakrabortty, Shakeel Ur Rahaman +1

We propose a Heat-Kernel-based method to compute one-loop effective action up to any mass-dimension with arbitrary numbers of non-degenerate scalars and fermions. We demonstrate ou…

One-loop Effective Action up to Dimension Eight: Integrating out Heavy Scalar(s)

Upalaparna Banerjee, Joydeep Chakrabortty, Shakeel Ur Rahaman +1

We present the complete one-loop effective action up to dimension eight after integrating out degenerate scalars using the Heat-Kernel method. The result is provided without assumi…

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…

Integrating out heavy scalars with modified EOMs: matching computation of dimension-eight SMEFT coefficients

Upalaparna Banerjee, Joydeep Chakrabortty, Christoph Englert +2

The shift in focus towards searches for physics beyond the Standard Model (SM) employing model-independent Effective Field Theory (EFT) methods necessitates a rigorous approach to…

Effective connections of , Higgs physics, and the collider frontier

Anisha, Upalaparna Banerjee, Joydeep Chakrabortty +3

We consider scalar extensions of the SM and their effective field theoretic generalisations to illustrate the phenomenological connection between precision measurements of the anom…

Extended Higgs sectors, effective field theory and Higgs phenomenology

Anisha, Upalaparna Banerjee, Joydeep Chakrabortty +2

We consider the phenomenological implications of charged scalar extensions of the SM Higgs sector in addition to EFT couplings of this new state to SM matter. We perform a detailed…

Effective Operator Bases for Beyond Standard Model Scenarios: An EFT compendium for discoveries

Upalaparna Banerjee, Joydeep Chakrabortty, Suraj Prakash +2

It is not only conceivable but likely that the spectrum of physics beyond the Standard Model (SM) is non-degenerate. The lightest non-SM particle may reside close enough to the ele…

Characters and Group Invariant Polynomials of (Super)fields: Road to "Lagrangian"

Upalaparna Banerjee, Joydeep Chakrabortty, Suraj Prakash +1

The dynamics of the subatomic fundamental particles, represented by quantum fields, and their interactions are determined uniquely by the assigned transformation properties, i.e.,…
