Decoding Nature with Nature's Tools: Heterotic Line Bundle Models of Particle Physics with Genetic Algorithms and Quantum Annealing

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

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 ...

Is the 125 GeV Higgs the superpartner of a neutrino? [PDF]

, 2012
Recent LHC searches have provided strong evidence for the Higgs, a boson whose gauge quantum numbers coincide with those of a SM fermion, the neutrino. This raises the mandatory question of whether Higgs and neutrino can be related by supersymmetry.

Gluino-mediated electroweak penguin with flavor-violating trilinear couplings

Journal of High Energy Physics, 2018
In light of a discrepancy of the direct CP violation in K → ππ decays, ε ′ /ε K , we investigate gluino contributions to the electroweak penguin, where flavor violations are induced by squark trilinear couplings.

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-

A microscopic theory of gauge mediation [PDF]

, 2011
We construct models of indirect gauge mediation where the dynamics responsible for breaking supersymmetry simultaneously generates a weakly coupled subsector of messengers.

Improved MSSM Higgs mass calculation using the 3-loop FlexibleEFTHiggs approach including x t -resummation

Journal of High Energy Physics, 2020
We present an improved calculation of the light CP-even Higgs boson pole mass in the MSSM based on the FlexibleEFTHiggs hybrid method. The calculation resums large logarithms to all orders and includes power-suppressed terms at fixed order. It uses state-

Aspects of Split Supersymmetry

, 2004
We explore some fundamental differences in the phenomenology, cosmology and model building of Split Supersymmetry compared with traditional low-scale supersymmetry.
