Status of the charged Higgs boson in two Higgs doublet models
European Physical Journal C: Particles and Fields, 2018 The existence of charged Higgs boson(s) is inevitable in models with two (or more) Higgs doublets. Hence, their discovery would constitute unambiguous evidence for new physics beyond the Standard Model (SM).

de Sitter Excited State in Heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ Theory
Fortschritte der Physik, Volume 73, Issue 12, December 2025.Abstract A novel duality sequence is devised to study late‐time cosmology in the heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ setup of Horava and Witten with dynamical walls that are moving towards each other. Remarkably, the dimensionally reduced 4‐dimensional theory does not violate NEC and no bouncing or ekpyrotic phase is observed.

Exploratory calculation of the rare hyperon decay Σ+ → pℓ + ℓ − from lattice QCD
Journal of High Energy PhysicsThe rare hyperon decay Σ+ → pℓ + ℓ − is a flavour-changing neutral current process mediated by an s → d transition that occurs only at loop level within the Standard Model.

Perturbative spacetimes from Yang-Mills theory
Journal of High Energy Physics, 2017 The double copy relates scattering amplitudes in gauge and gravity theories. In this paper, we expand the scope of the double copy to construct spacetime metrics through a systematic perturbative expansion.

Proceedings of The 39th International Conference on High Energy Physics — PoS(ICHEP2018), 2019 The Compact Linear Collider (CLIC) is a mature option for a future electron-positron collider operating at centre-of-mass energies of up to 3 TeV. CLIC will be built and operated in a staged approach with three centre-of-mass energy stages currently assumed to be 380 GeV, 1.5 TeV and 3 TeV.

, 2001 We outline the unique role of a muon collider as a Higgs factory for Higgs boson resonance production in the $s$-channel. Physics examples include: the precision measurements of the Higgs mass and total width, and the resulting ability to discriminate between the SM-like Higgs bosons of different models such as between a light SM Higgs boson and the ...

Unitarity and predictiveness in new Higgs inflation
Journal of High Energy Physics, 2018 In new Higgs inflation the Higgs kinetic terms are non-minimally coupled to the Einstein tensor, allowing the Higgs field to play the role of the inflaton.

, 1997 Higgs boson production at the LHC within the Standard Model and its minimal supersymmetric extension is reviewed. The predictions for decay rates and production cross sections are updated by choosing the present value of the top quark mass and recent parton density sets.
