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

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 ...

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.

Phenomenology of Dirac Neutrinogenesis in Split Supersymmetry

, 2005
In Split Supersymmetry scenarios the possibility of having a very heavy gravitino opens the door to alleviate or completely solve the worrisome "gravitino problem'' in the context of supersymmetric baryogenesis models.

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 ...

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 ...

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.

Models of Particle Physics from Type IIB String Theory and F-theory: A Review [PDF]

, 2012
We review particle physics model building in type IIB string theory and F-theory. This is a region in the landscape where in principle many of the key ingredients required for a realistic model of particle physics can be combined successfully.

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 ...

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.
