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-

Lepton flavor violation beyond the MSSM [PDF]

, 2015
Most extensions of the Standard Model lepton sector predict large lepton flavor violating rates. Given the promising experimental perspectives for lepton flavor violation in the next few years, this generic expectation might offer a powerful indirect ...

Goldstini [PDF]

, 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 ...

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.

Probing SUSY effects in K S 0 → μ + μ −

Journal of High Energy Physics, 2018
We explore supersymmetric contributions to the decay K S 0 → μ + μ −, in light of current experimental data. The Standard Model (SM) predicts ℬKS0→μ+μ−≈5×10−12 $$ \mathrm{\mathcal{B}}\left({K}_S^0\to {\mu}^{+}{\mu}^{-}\right)\approx 5\times {10}^{-12} $$.

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.

Moduli and multi-field inflation [PDF]

, 2007
Moduli with flat or run-away classical potentials are generic in theories based on supersymmetry and extra dimensions. They mix between themselves and with matter fields in kinetic terms and in the nonperturbative superpotentials.

Exploring the nearly degenerate stop region with sbottom decays

Journal of High Energy Physics, 2017
A light stop with mass almost degenerate with the lightest neutralino has important connections with both naturalness and dark matter relic abundance. This region is also very hard to probe at colliders.

Gaugino Condensates and Fluxes in N = 1 Effective Superpotentials

, 2007
In the framework of orbifold compactifications of heterotic and type II orientifolds, we study effective N = 1 supergravity potentials arising from fluxes and gaugino condensates.
