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 ...

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,

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.

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.

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-

Phenomenological consequences of supersymmetry with anomaly induced masses [PDF]

Nuclear Physics B, 1999
In the supersymmetric standard model there exist pure gravity contributions to the soft mass parameters which arise via the superconformal anomaly. We consider the low-energy phenomenology with a mass spectrum dominated by the anomaly-induced contributions.

Metastable Vacua in Flux Compactifications and Their Phenomenology [PDF]

, 2006
In the context of flux compactifications, metastable vacua with a small positive cosmological constant are obtained by combining a sector where supersymmetry is broken dynamically with the sector responsible for moduli stabilization, which is known as ...

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-

Phenomenology of Universal Extra Dimensions

, 2006
In this proceeding, the phenomenology of Universal Extra Dimensions (UED), in which all the Standard Model fields propagate, is explored. We focus on models with one universal extra dimension, compactified on an $S_1/Z_2$ orbifold.
