BSM patterns in scalar-sector coupling modifiers

open access: yesJournal of High Energy Physics, 2023
We consider what multiple Higgs interactions may yet reveal about the scalar sector. We estimate the sensitivity of a Feynman topology-templated analysis of weak boson fusion Higgs pair production at present and future colliders — where the signal is a ...

Recent Highlights on Higgs Physics from the LHC

open access: yesSciPost Physics Proceedings, 2022
Many of the Higgs boson production and decay channels, predicted by the StandardModel, have been observed since its 2012 discovery. Today, measurements of the Higgsboson’s properties in these channels deepen our understanding of the nature of ...

Measurements of Higgs boson production in the decay channel with a pair of $$\uptau $$ τ leptons in proton–proton collisions at $$\sqrt{s}=13$$ s = 13 TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Measurements of Higgs boson production, where the Higgs boson decays into a pair of $$\uptau $$ τ leptons, are presented, using a sample of proton-proton collisions collected with the CMS experiment at a center-of-mass energy of , corresponding to an ...

SUSY Enhancement of Heavy Higgs Production [PDF]

open access: yesProceedings of The XXth International Workshop High Energy Physics and Quantum Field Theory — PoS(QFTHEP2011), 2011
We study the cross-section of heavy Higgs production at the LHC within the framework of the constrained MSSM. It is not only enhanced by tan 2β but sometimes is also enhanced by the squark contribution. First, we consider the universal scenario within mSUGRA and find out that to get the desired enhancement one needs large negative values of A0, which ...

Photo-production of the Higgs boson at the LHeC

open access: yesNuclear Physics B, 2020
As one category of vector boson fusion, photo-production is one important production mechanism at e-p colliders. A future e-p collider – Large Hadron-electron Collider (LHeC) has been discussed as a “Higgs factory” candidate where the Higgs boson ...

Light-quark Yukawa couplings from off-shell Higgs production

open access: yesJournal of High Energy Physics, 2023
Yukawa couplings of the first quark generation are notoriously difficult to constrain due to their small values within the Standard Model. Here we propose Higgs off-shell production, with the Higgs boson decaying to four leptons, as a probe of the up ...

Measuring single-top-associated Higgs production at the HL-LHC

open access: yesSciPost Physics Proceedings, 2022
Precision measurements of top-associated Higgs production are an important ingredient to unravel the $\mathcal{CP}$ nature of the Higgs boson. In this work, we constraint the $\mathcal{CP}$ nature of the top-Yukawa coupling taking into account all ...

Higgs pair production in the composite Higgs model [PDF]

open access: yesProceedings of Proceedings of the Corfu Summer Institute 2011 — PoS(CORFU2011), 2012
In composite Higgs models the Higgs boson arises as a pseudo Nambu-Goldstone boson of an enlarged global symmetry. The Higgs potential is generated by loops of Standard Model fermions and gauge bosons. To reconstruct the Higgs potential trilinear and quartic couplings must be measured.

Single production of charged Higgs bosons at linear colliders [PDF]

open access: yes, 2000
We discuss single charged Higgs boson production from $e^+e^-$ annihilation at next generation linear colliders. They can be important to study the phenomenology of charged Higgs bosons, especially when charged Higgs bosons are too heavy to be produced ...

Higgs-pair production and decay in simplest little Higgs model [PDF]

open access: yesNuclear Physics B, 2010
In the framework of the simplest little Higgs model (SLHM), we study the production of a pair of neutral CP-even Higgs bosons at the LHC. First, we examine the production rate and find that it can be significantly larger than the SM prediction. Then we investigate the decays of the Higgs-pair and find that for a low Higgs mass their dominant decay mode
