Weak boson probes of Higgs unitarity restoration at 10 TeV parton colliders
Christoph Englert, Wrishik Naskar, Andrew D. Pilkington +1
Higgs coupling deviations, at levels accessible to the high-luminosity LHC, can imply a phenomenological no-lose theorem for the next generation of collider facilities. Correlating…
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^-…
