Quadruple-Higgs boson production at the high-luminosity LHC

Andreas Papaefstathiou, Gilberto Tetlalmatzi-Xolocotzi

We investigate the production of four Higgs bosons via gluon fusion at the high-luminosity LHC. We construct a phenomenological analysis of the eight--jet final state and use a…

Polarized Deep-Inelastic Scattering with Spin Correlations in Herwig 7

M. R. Masouminia, A. Papaefstathiou, P. Richardson

We investigate polarized deep-inelastic scattering (DIS) in the context of fully exclusive Monte Carlo simulations for the Electron-Ion Collider (EIC). We present a next-to-leading…

Extracting Higgs Self-Coupling Constraints through Triple Higgs Boson Production at Future Hadron Colliders

Benjamin Fuks, Andreas Papaefstathiou, Gilberto Tetlalmatzi-Xolocotzi

We present a systematic study of triple Higgs boson production at future high-energy hadron colliders, using the six--jet final state as a probe of the Higgs self-interactions.…

Triple Higgs boson production and electroweak phase transition in the two-real-singlet model

Osama Karkout, Andreas Papaefstathiou, Marieke Postma +3

The production of three Higgs bosons at hadron colliders can be enhanced by a double-resonant effect in the -symmetric two-real-singlet extension of the Standard Mode…

Investigating the Electroweak Phase Transition with a Real Scalar Singlet at a Muon Collider

Mohamed Aboudonia, Csaba Balazs, Andreas Papaefstathiou +1

A strong first-order electroweak phase transition (SFOEWPT) is essential for explaining baryogenesis and for potentially generating observable gravitational waves. This study inves…

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…
