Tachyonic de Sitter Solutions of 10d Type II Supergravities
Fortschritte der Physik, Volume 69, Issue 7, July 2021., 2021 Abstract Cosmological models of the early or late universe exhibit (quasi) de Sitter space‐times with different stability properties. Considering models derived from string theory, the swampland program does not provide for now a definite characterisation of this stability.

Interpolation of partial and full supersymmetry breakings in N=2 supergravity
Nuclear Physics B, 2019 We discuss an N=2 supergravity model that interpolates the full and the partial supersymmetry breakings. In particular, we find the conditions for an N=0 Minkowski vacuum, which is continuously connected to the partial-breaking (N=1 preserving) one.

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.

TASI Lectures on M Theory Phenomenology [PDF]
, 2000 These lectures discuss some of the general issues in developing a phenomenology for Superstring Theory/M Theory. The focus is on the question: how might one obtain robust, generic predictions. For example, does the theory predict low energy supersymmetry

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.

The scale of supersymmetry breaking as a free parameter [PDF]
, 2001 While supersymmetric extensions of the Standard Model can be fully described in terms of explicitly broken global supersymmetry, this description is only effective.

Resummation of terms enhanced by trilinear squark-Higgs couplings in the MSSM
Journal of High Energy Physics, 2021 We analyze the appearance of the trilinear squark-Higgs couplings x q in Green functions in the Higgs sector of the MSSM and in threshold corrections to the SM. The results are constraints on maximal powers of x q in QCD-related loop corrections.

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.

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 ...
