Effective Quantum Field Theory and SMEFT
Anisha, Anke Biekötter, Matthias König
We introduce the basics of Effective Field Theories, using the Standard Model Effective Field Theory as our central example. The first part of this chapter gives a pedagogical intr…
Exploring Extended Higgs Dynamics via Higgsstrahlung at FCC-ee
Anisha, Francisco Arco, Stefano Di Noi +2
The Future Circular Electron-Positron Collider (FCC-ee) will probe aspects of the Higgs boson and the electroweak scale with unprecedented precision via associated Higgs production…
Phenomenology of a Kinetic Higgs Portal
Anisha, Lisa Biermann, Christoph Englert +1
We explore the phenomenological consequences of non-minimal hidden sector interactions on observable correlations in the Higgs sector, mediated through the -symmetric…
Z and Higgs Factory Implications of Two Higgs Doublets with First-Order Phase Transitions
Anisha, Francisco Arco, Stefano Di Noi +2
We investigate the potential of future electron-positron colliders, such as FCC-ee and CEPC, to probe 2-Higgs-doublet models (2HDMs) that facilitate a strong first-order electrowea…
HEFT's appraisal of triple (versus double) Higgs weak boson fusion
Anisha, Daniel Domenech, Christoph Englert +2
Multi-Higgs boson interactions with massive gauge bosons are known to be tell-tale probes of the vacuum manifold of electroweak symmetry breaking. Phenomenologically, a precise det…
Bosonic multi-Higgs correlations beyond leading order
Anisha, Daniel Domenech, Christoph Englert +2
The production of multiple Higgs bosons at the LHC and beyond is a strong test of the mechanism of electroweak symmetry breaking. Taking inspiration from recent experimental effort…
Higgs boson off-shell measurements probe non-linearities
Anisha, Christoph Englert, Roman Kogler +1
The measurements of off-shell Higgs boson contributions in massive gauge boson pair production are known to probe its electroweak interactions across different energy scales. Often…
Effective 2HDM Yukawa Interactions and a Strong First-Order Electroweak Phase Transition
Anisha, Duarte Azevedo, Lisa Biermann +2
The top quark as the heaviest particle in the Standard Model (SM) defines an important mass scale for Higgs physics and the electroweak scale itself. It is therefore a well-motivat…
Higgs Footprints of Hefty ALPs
Anisha, Supratim Das Bakshi, Christoph Englert +1
We discuss axion-like particles (ALPs) within the framework of Higgs Effective Field Theory, targeting instances of close alignment of ALP physics with a custodial singlet characte…
On the BSM reach of four top production at the LHC
Anisha, Oliver Atkinson, Akanksha Bhardwaj +3
Many scenarios of beyond the Standard Model (BSM) physics give rise to new top-philic interactions that can be probed at proton machines such as the Large Hadron Collider through a…
Quartic Gauge-Higgs couplings: Constraints and Future Directions
Anisha, Oliver Atkinson, Akanksha Bhardwaj +2
Constraints on quartic interactions of the Higgs boson with gauge bosons have been obtained by the experimental LHC collaborations focussing on the so-called framework of flat…
Two Higgs doublets, Effective Interactions and a Strong First-Order Electroweak Phase Transition
Anisha, Lisa Biermann, Christoph Englert +1
It is well-known that type II two Higgs doublet models (2HDMs) can struggle to facilitate a strong first-order electroweak phase transition in the early universe whilst remaining t…
Effective limits on single scalar extensions in the light of recent LHC data
Anisha, Supratim Das Bakshi, Shankha Banerjee +4
In this paper, we work with 16 different single scalar particle extensions of the Standard Model. We present the sets of dimension-6 effective operators and the associated Wilson c…
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…
A Step Toward Model Comparison: Connecting Electroweak-Scale Observables to BSM through EFT and Bayesian Statistics
Anisha, Supratim Das Bakshi, Joydeep Chakrabortty +1
Recognizing the potential of effective field theories to posit multiple BSM scenarios in similar footing, with a possibility to compare them, we inspect the effects of 11 single sc…
Hilbert Series and Plethystics: Paving the path towards 2HDM- and MLRSM-EFT
Anisha, Supratim Das Bakshi, Joydeep Chakrabortty +1
Effective Field Theory technique is one of the most elegant ways to capture the impact of high scale theory, if any, at some low energy by incorporating higher mass dimensional ($\…
