Simultaneous search for extra light and heavy Higgs bosons via cascade decays

open access: yesJournal of High Energy Physics, 2017
Models with extended Higgs sectors can contain several additional Higgs states, heavier or lighter than the SM Higgs boson. The couplings of lighter extra states to SM particles can be strongly reduced, leading to small cross sections for their direct ...

Relational Supersymmetry via the Dressing Field Method and Matter‐Interaction Supergeometric Framework

open access: yesAnnalen der Physik, Volume 537, Issue 9, September 2025.
Applications of the Dressing Field Method are reviewed and further expanded to the very foundations of the supersymmetric framework, where it allows to build relational supersymmetric field theory. Furthermore, a novel approach is proposed giving a unified description of fermionic matter fields and bosonic gauge fields: a Matter‐Interaction ...

Gauge Mediated Supersymmetry Breaking in Five Dimensions

open access: yes, 2011
PhDIn this thesis we focus on the construction of models in which a supersymmetry breaking hidden sector is located on one fixed point of an extra dimensional interval and the effects are gauge mediated across this interval to the other fixed point ...

Higgs Sector in Extensions of the Minimal Supersymmetric Standard Model

open access: yes, 2006
Extensions of the minimal supersymmetric standard model (MSSM) with additional singlet scalar fields solve the important µ-parameter fine-tuning problem of the MSSM.We compute and compare the neutral Higgs boson mass spectra, including one-loop ...

Search for pair production of massive particles decaying into three quarks with the ATLAS detector in root s=7 TeV pp collisions at the LHC [PDF]

open access: yes, 2012
ATLAS Collaboration Contributor: P. JacksonA search is conducted for hadronic three-body decays of a new massive coloured particle in √s=7 TeV pp collisions at the LHC using an integrated luminosity of 4.6 fb−1 collected by the ATLAS detector ...

Long live the Higgs portal!

open access: yesJournal of High Energy Physics, 2019
In Higgs portal models of fermion dark matter, scalar couplings are unavoidably suppressed by strong bounds from direct detection experiments. As a consequence, thermal dark matter relics must coexist with mediators in a compressed spectrum of dark ...

Taking limits in topological recursion

open access: yesJournal of the London Mathematical Society, Volume 112, Issue 3, September 2025.
Abstract When does topological recursion applied to a family of spectral curves commute with taking limits? This problem is subtle, especially when the ramification structure of the spectral curve changes at the limit point. We provide sufficient (straightforward‐to‐use) conditions for checking when the commutation with limits holds, thereby closing a ...

Higher order and CP-violating effects in the neutralino and Higgs boson sectors of the MSSM [PDF]

open access: yes, 2010
Complete one-loop results are presented for neutralino and Higgs decay processes of the form chi^0_i->chi^0_j h_a and h_a->chi^0_i chi^0_j in the MSSM with CP-violating parameters.

A supersymmetric electroweak scale seesaw model

open access: yesJournal of High Energy Physics, 2017
In this paper we propose a novel supersymmetric inverse seesaw model which has only one additional Z 6 symmetry. The field content is minimal to get a viable neutrino spectrum at tree-level. Interestingly, the inverse seesaw scale in our model is related

THE NEXT TO MINIMAL SUPERSYMMETRIC STANDARD MODEL WITH A MODERATE STOP MASS

open access: yes, 2008
In this thesis we analize the Next to Minimal Supersymmetric Standard Model (NMSSM), looking for a natural electroweak symmetry breaking. Focusing on a moderate stop mass and requiring perturbative unification of the gauge couplings (which after all is a
