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…
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…
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…
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 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…
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…
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…
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 ($\…
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…
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…
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…
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…
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…
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…
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…
