Does SUSY have friends? A new approach for LHC event analysis
Journal of High Energy Physics, 2021 We present a novel technique for the analysis of proton-proton collision events from the ATLAS and CMS experiments at the Large Hadron Collider. For a given final state and choice of kinematic variables, we build a graph network in which the individual ...

Fortschritte der Physik, Volume 72, Issue 2, February 2024.Abstract The string theory landscape may include a multitude of ultraviolet embeddings of the Standard Model, but identifying these has proven difficult due to the enormous number of available string compactifications. Genetic Algorithms (GAs) represent a powerful class of discrete optimisation techniques that can efficiently deal with the immensity of

Neutrino Phenomenology of a High Scale Supersymmetry Model* [PDF]
Communications in Theoretical Physics, 2019 Abstract CP violation in the lepton sector, and other aspects of neutrino physics, are studied within a high scale supersymmetry model. In addition to the sneutrino vacuum expectation values (VEVs), the heavy vector-like triplet also contributes to neutrino masses.

Moduli stabilization, de Sitter vacua and supersymmetry breaking [PDF]
, 2016 We describe the phenomenology of a model of supersymmetry breaking in the presence of a tiny (tunable) positive cosmological constant. It utilises a single chiral multiplet with a gauged shift symmetry, that can be identified with the string dilaton (or ...

Journal of High Energy Physics, 2019 We study baryogenesis via a gaugino portal, the supersymmetric counterpart to the widely studied kinetic mixing portal, to a hidden sector. CP and baryon number violating decays of a hidden sector gaugino into the visible sector can produce the observed ...

Split Supersymmetry at Colliders [PDF]
, 2004 We consider the collider phenomenology of split-supersymmetry models. We show that despite the challenging nature of the signals in these models the long-lived gluino can be discovered with masses in excess of 2 TeV at the LHC.

Enhancing the discovery prospects for SUSY-like decays with a forgotten kinematic variable
Journal of High Energy Physics, 2019 The lack of a new physics signal thus far at the Large Hadron Collider motivates us to consider how to look for challenging final states, with large Standard Model backgrounds and subtle kinematic features, such as cascade decays with compressed spectra.

Comparative studies of 2HDMs under the Higgs boson precision measurements
Journal of High Energy Physics, 2021 We perform comparative studies for four types of the two Higgs Doublet Models (2HDMs) under the precision measurements of the Standard Model (SM) Higgs observables at the proposed Higgs factories.

Evidence for a Phenomenological Supersymmetry in Atomic Physics [PDF]
Physical Review Letters, 1984 We show that supersymmetric quantum mechanics may be used to interrelate the spectra of different atoms and ions. This supersymmetry is broken by electron-electron interactions.
