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 $$ \mathrm{\mathcal{B}}\left({K}_S^0\to {\mu}^{+}{\mu}^{-}\right)\approx 5\times {10}^{-12} $$.

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.

Supersymmetric flaxion

Journal of High Energy Physics, 2018
Recently, a new minimal extension of the Standard Model has been proposed, where a spontaneously broken, flavor-dependent global U(1) symmetry is introduced.

Explaining electron and muon g − 2 anomaly in SUSY without lepton-flavor mixings

Journal of High Energy Physics, 2019
We propose a SUSY scenario to explain the current electron and muon g − 2 discrepancies without introducing lepton flavor mixings. Threshold corrections to the Yukawa couplings can enhance the electron g − 2 and flip the sign of the SUSY contributions ...

Phenomenology of Low-Scale Supersymmetry Breaking Models [PDF]

Modern Physics Letters A, 2003
In this review we consider the distinctive phenomenology of supersymmetric models in which the scale of SUSY breaking is very low, [Formula: see text], focusing on the Higgs sector and the process of electroweak breaking. Using an effective Lagrangian description of the interactions between the observable fields and the SUSY breaking sector, it is ...

Report of the Beyond the MSSM Subgroup for the Tevatron Run II SUSY/Higgs Workshop [PDF]

, 2000
There are many low-energy models of supersymmetry breaking parameters which are motivated by theoretical and experimental considerations. Here, we discuss some of the lesser-known theories of low-energy supersymmetry, and outline their phenomenological ...

Mass hierarchy from the flavor symmetry in supersymmetric multi-Higgs doublet model

Journal of High Energy Physics, 2020
We study the supersymmetric standard model with multiple Higgs doublets with gauged U(1) X flavor symmetry. When the flavor symmetry is broken by the vacuum expectation value of flavon, the ℤ3 symmetry M 3 called matter triality remains and it prohibits ...

A Complete Model of Low-Scale Gauge Mediation

, 2012
Recent signs of a Standard Model-like Higgs at 125 GeV point towards large A-terms in the MSSM. This presents special challenges for gauge mediation, which by itself predicts vanishing A-terms at the messenger scale.

Multilepton signals of heavier electroweakinos at the LHC

Journal of High Energy Physics, 2017
As a sequel to our recent paper we examine the phenomenology of the full electroweakino sector of the pMSSM without invoking the ad hoc but often employed assumption that the heavier ones are decoupled.
