Assessing (H)EFT theory errors by pitting EoM against Field Redefinitions
Rodrigo Alonso, Christoph Englert, Wrishik Naskar +1
Truncations of effective field theory expansions are technically necessary but inherently intertwined with the redundancies of general field redefinitions. This can be viewed as a…
Future Collider Perspectives on Higgs CP Violation
Arun Atwal, Jessica Burridge, António Jacques Costa +9
The search for new sources of CP violation is a cornerstone of the beyond the Standard Model phenomenology programme at the LHC and beyond. We provide a comprehensive analysis of s…
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…
Gauge Choices, Infrared Pitfalls, and Thermal Effects in Effective Potentials
Debanjan Balui, Tisa Biswas, Joydeep Chakrabortty +3
The evaluation of effective potentials is critical for a range of phenomenological applications, including inflation, vacuum stability, and phase transitions. A drawback arises fro…
Harnessing Higgs Kinematics for HEFT Constraints
Christoph Englert, Tom Ingebretsen Carlson, Jörgen Sjölin +1
We present a momentum-dependent reweighting strategy to extend current LHC di-Higgs analyses within the -framework and SMEFT into the bosonic sector of the Higgs Effective Field…
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…
Distorting the Top Resonance with Effective Interactions
Felix Egle, Christoph Englert, Margarete Mühlleitner +1
Interference effects in effective field theory (EFT) analyses can significantly distort sensitivity expectations, leaving subtle yet distinct signatures in the reconstruction of fi…
A anomaly motivated boson at the energy and precision frontiers
Ben Allanach, Christoph Englert, Wrishik Naskar
TeV-scale bosons with family-dependent couplings can explain some anomalies inferred from meson measurements of processes involving the $b \rightarrow s \ell^+\ell^-…
Electroweak Scalar Effects Beyond Dimension-6 in SMEFT
Nilabhra Adhikary, Tisa Biswas, Joydeep Chakrabortty +2
The Standard Model Effective Field Theory (SMEFT) provides a robust framework for probing deviations in the couplings of Standard Model particles from their theoretical predictions…
Impact of New Physics on Momentum-Dependent Particle Widths and Propagators
Christoph Englert, Wrishik Naskar, Michael Spannowsky
We investigate the impact of momentum-dependent particle widths and propagators on gauge and Higgs bosons and the top quark within the Standard Model (SM) and its SMEFT extensions…
