On the robustness of the indirect determination of the width of the detected Higgs boson
Panagiotis Stylianou, Georg Weiglein
The indirect determination of the total width of the detected Higgs boson that is carried out by the experimental collaborations at the LHC relies on the assumption that the coupli…
Complementarity of di-top and four-top searches in interpreting possible signals of new physics
Henning Bahl, Philipp Gadow, Romal Kumar +3
Final states comprising two or more top quarks are important search channels at the Large Hadron Collider for scalar particles predicted in models of physics beyond the Standard Mo…
EVAluation of the Equivalent Vector Boson Approximation at highest energy colliders
Benjamin Dahlén, Maximilian Löschner, Krzysztof Mękała +2
Collider processes at the highest available partonic center-of-mass energies - 10 TeV and above - exhibit a new regime of electroweak interactions where electroweak gauge bosons mo…
Top-quark spin correlations as a tool to distinguish pseudoscalar and scalar signatures in final states at the LHC
Francisco Arco, Thomas Biekötter, Panagiotis Stylianou +1
Both ATLAS and CMS have recently performed the first searches for a heavy new spin-0 resonance decaying into a lighter new spin-0 resonance and a boson, where the lighter spin-…
Probing the Inert Doublet Model via Vector-Boson Fusion at a Muon Collider
Johannes Braathen, Martin Gabelmann, Tania Robens +1
In this work, we explore the discovery potential of the Inert Doublet Model (IDM) via the vector boson fusion (VBF) channel at a muon collider with centre-of-mass energy of 10 TeV.…
HHH Whitepaper
Vuko Brigljevic, Dinko Ferencek, Greg Landsberg +31
We here report on the progress of the HHH Workshop, that took place in Dubrovnik in July 2023. After the discovery of a particle that complies with the properties of the Higgs boso…
Constraints on the trilinear and quartic Higgs couplings from triple Higgs production at the LHC and beyond
Panagiotis Stylianou, Georg Weiglein
Experimental information on the trilinear Higgs boson self-coupling and the quartic self-coupling will be crucial for gaining insight into the shape of the Higgs potent…
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…
Implications of the muon anomalous magnetic moment for the LHC and MUonE
Akanksha Bhardwaj, Christoph Englert, Panagiotis Stylianou
We consider the anomalous magnetic moment of the muon , which shows a significant deviation from the Standard Model expectation given the recent measurements at Fermilab and B…
