R-parity violating chargino decays at the LHC [PDF]
A bstractSupersymmetric models with R-parity violation (RPV) have become more popular following the lack of any excess of missing energy events at the 8 TeV LHC. To identify such models, the suggested searches generally rely on the decay products of the (

Oblique Corrections in the MSSM at One‐Loop—Part I: Scalars
This paper is devoted to reconsider the one‐loop oblique corrections arising from the scalar superpartners in the MSSM, that is, the squarks, the sleptons, and the scalars in Higgs sector. We explicitly present the complete one‐loop forms of self‐energy corrections to the gauge bosons of SM electroweak gauge groups, as well as their descendants the S ...

Chargino Pair Production at $e^+e^-$ Colliders with Polarized Beams [PDF]
The chargino $\tilde{\chi}^\pm_{1,2}$ system can be reconstructed completely in $e^+e^-$ collisions. By measuring the total cross sections and the asymmetries with polarized beams in $e^+e^-\to\tilde{\chi}_i^+ \tilde{\chi}_j^- [i,j=1,2]$, the chargino ...

Heavy Chiral Fermions and Dark Matter
Dark matter presents perhaps one of the most compelling direct indications of new physics beyond the standard model with three generations of fermions. In this paper, we survey several scenarios for dark matter in association with a fourth generation of chiral matter.

Polarized Charginos (and Tops) in Stop Decays
Current searches for direct production of scalar top quarks, or stops, in supersymmetry focus on their decays into W boson + b quark + neutralino by way of top + neutralino and bottom + chargino.

Spin and spin-spin correlations in chargino pair production at future linear e+e- colliders [PDF]
A possibility to measure the spin and spin-spin correlations of a chargino pair is investigated in the process electron positron -> chargino_1 anti-chargino_1 -> (neutralino_1 quark anti-quark) (neutralino_1 quark anti-quark) at future linear-collider ...

A Comparative Study of Dark Matter in the MSSM and Its Singlet Extensions: A Mini Review
In this note we briefly review the recent studies of dark matter in the MSSM and its singlet extensions: the NMSSM, the nMSSM, and the general singlet extension. Under the new detection results of CDMS II, XENON, CoGeNT, and PAMELA, we find that (i) the latest detection results can exclude a large part of the parameter space which is allowed by current

Explanation of electron and muon g − 2 anomalies in the MSSM
The current experimental values of anomalous magnetic moments of muon and electron deviate from the Standard Model predictions by few standard deviations, which might be a hint of new physics.
