Scale hierarchies in particle physics and cosmology
EPJ Web of Conferences, 2018 I describe the phenomenology of a model of supersymmetry breaking in the presence of a tiny (tuneable) positive cosmological constant. It utilises a single chiral multiplet with a gauged shift symmetry, that can be identified with the string dilaton (or ...

On a reinterpretation of the Higgs field in supersymmetry and a proposal for new quarks
Physics Letters B, 2017 In the framework of supersymmetry, when R-parity is violated the Higgs doublet superfield Hd can be interpreted as another doublet of leptons, since all of them have the same quantum numbers. Thus Higgs scalars are sleptons and Higgsinos are leptons.

Gravitational waves from first-order electroweak phase transition in a model with light sgoldstinos
Journal of High Energy Physics, 2022 We study previously unexplored possibility of triggering the first order electroweak phase transition (EWPT) by interactions of the Standard Model (SM) particles with the sector responsible for low scale supersymmetry breaking.

, 2010 Supersymmetric phenomenology has been largely bound to the hypothesis that supersymmetry breaking originates from a single source. In this paper, we relax this underlying assumption and consider a multiplicity of sectors which independently break ...

Scale Hierarchies in Particle Physics and Cosmology
EPJ Web of Conferences, 2016 We discuss possible connections between several scales in particle physics andcosmology, such the the electroweak, inflation, dark energy and Planck scales.

t − b − τ Yukawa unification in non-holomorphic MSSM
Journal of High Energy Physics, 2021 We show that in the CMSSM with the non-holomorphic soft SUSY breaking terms, the Yukawa coupling unification of the third family fermions at the GUT scale, called t − b − τ Yukawa unification (YU), is possible under the recent collider and Dark Matter ...

Non-Minimal and Non-Universal Supersymmetry [PDF]
, 2000 I motivate and discuss non-minimal and non-universal models of supersymmetry and supergravity consistent with string unification at $10^{16}$ GeV.Comment: 10 pages, Latex. Plenary talk given at 6th Workshop in High Energy Physics Phenomenology (WHEPP 6)

Strong first order electroweak phase transition in 2HDM confronting future Z & Higgs factories
Journal of High Energy Physics, 2021 The electroweak phase transition can be made first order by extending the Standard Model (SM) Higgs sector with extra scalars. The same new physics can explain the matter-antimatter asymmetry of the universe by supplying an extra source of CP violation ...

Probing minimal SUSY scenarios in the light of muon g−2 and dark matter
Journal of High Energy Physics, 2017 We study supersymmetric (SUSY) models in which the muon g −2 discrepancy and the dark matter relic abundance are simultaneously explained. The muon g − 2 discrepancy, or a 3σ deviation between the experimental and theoretical results of the muon ...

Muon g − 2 in gauge mediation without SUSY CP problem
Journal of High Energy Physics, 2021 We discuss gauge mediated supersymmetry breaking models which explain the observed muon anomalous magnetic moment and the Higgs boson mass simultaneously.
