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

Magnifying the ATLAS stealth stop splinter: impact of spin correlations and finite widths
Journal of High Energy Physics, 2018 In this paper, we recast a “stealth stop” search in the notoriously difficult region of the stop-neutralino Simplified Model parameter space for which mt˜1−mχ˜10≃mt $$ m\left({\tilde{t}}_1\right)-m\left({\tilde{\upchi}}_1^0\right)\simeq {m}_t $$.

Low-energy phenomenology of broken supersymmetry [PDF]
Physics Letters B, 1982 Abstract In a class of theories with spontaneously broken supersymmetry the lightest supersymmetric particles are expected to be neutral fermions with masses m W ) which are mainly supersymmetric partners of Higgses. while gauginos, squarks and sleptons are expected to be somewhat heavier. We discuss the low-energy phenomenology of such theories,

Gaugino-Assisted Anomaly Mediation [PDF]
, 2000 We present a model of supersymmetry breaking mediated through a small extra dimension. Standard model matter multiplets and a supersymmetry-breaking (or ``hidden'') sector are confined to opposite four-dimensional boundaries while gauge multiplets live ...

Exploring charge and color breaking vacuum in non-holomorphic MSSM
Journal of High Energy Physics, 2017 Non-Holomorphic MSSM (NHSSM) shows various promising features that are not easily obtained in MSSM. However, the additional Non-Holomorphic (NH) trilinear interactions that attribute to the interesting phenomenological features, also modify the effective

Phenomenological implications of supersymmetry breaking by the dilaton [PDF]
Physics Letters B, 1993 We investigate the low energy properties of string vacua with spontaneously broken $N=1$ supersymmetry by a dilaton $F$-term. As a consequence of the universal couplings of the dilaton, the supersymmetric mass spectrum is determined in terms of only three independent parameters and more constrained than in the minimal supersymmetric Standard Model. For

Gluino Condensation in Strongly Coupled Heterotic String Theory [PDF]
, 1996 Strongly coupled heterotic $E_8\times E_8$ string theory, compactified to four dimensions on a large Calabi-Yau manifold ${\bf X}$, may represent a viable candidate for the description of low-energy particle phenomenology.

Resonant slepton production and right sneutrino dark matter in left-right supersymmetry
Journal of High Energy Physics, 2017 Right-handed sneutrinos are natural components of left-right symmetric supersymmetric models where the gauge sector is extended to include right-handed weak interactions.

Boosted decision trees in the era of new physics: a smuon analysis case study
Journal of High Energy Physics, 2022 Machine learning algorithms are growing increasingly popular in particle physics analyses, where they are used for their ability to solve difficult classification and regression problems. While the tools are very powerful, they may often be under- or mis-
