SUSY Enhancement of Heavy Higgs Production [PDF]
Proceedings 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 ...

BSM patterns in scalar-sector coupling modifiers
Journal 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 ...

Measuring single-top-associated Higgs production at the HL-LHC
SciPost 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, di-Higgs and tri-Higgs production via SUSY processes at the LHC with 14 TeV [PDF]
, 2015 We have systematically investigated the production of a Higgs boson with a mass of about $125$ GeV in the decays of supersymmetric particles within the phenomenological MSSM (pMSSM).

Light-quark Yukawa couplings from off-shell Higgs production
Journal 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 ...

New results for a photon-photon collider [PDF]
, 2002 We present new results from studies in progress on physics at a two-photon collider. We report on the sensitivity to top squark parameters of MSSM Higgs boson production in two-photon collisions; Higgs boson decay to two photons; radion production in ...

Higgs pair production in the composite Higgs model [PDF]
Proceedings 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.

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

Probing the symmetric Higgs portal with di-Higgs boson production [PDF]
Physical Review D, 2019 A coupling of a scalar, charged under an unbroken global U(1) symmetry, to the Standard Model via the Higgs portal is one of the simplest gateways to a dark sector. Yet, for masses $m_{S}\geq m_{H}/2$ there are few probes of such an interaction. In this note we evaluate the sensitivity to the Higgs portal coupling of di-Higgs boson production at the ...
