Chargino mass and Rb anomaly [PDF]

open access: greenNuclear Physics B, 1996
We re-examine the possible magnitude of the supersymmetric contribution to $R_b$ with imposed all available phenomenological constraints and demanding good quality of the global fit to the precision electroweak data. For low $\tan $ we find a new region of the parameter space, with $M_2\approx | |$ and $ <0$ where $R_b$ remains large, $\sim0.2180$

SUSY Parameters from Charginos [PDF]

open access: green, 2002
The chargino pair production processes at $e^+e^-$ collisions are explored to reconstruct the fundamental SUSY parameters: the SU(2) gaugino parameter $M_2$, the higgsino mass parameter $ $ and $\tan $. Both CP-conserving and CP-violating SUSY sectors are discussed.

Prospects for chargino pair production at the CEPC * [PDF]

open access: yesChinese Physics C, 2022
Abstract The proposed Circular Electron Positron Collider (CEPC) with a center-of-mass energy GeV will primarily serve as a Higgs factory. Additionally, it will offer good opportunities to search for new physics phenomena at low energies, which can be challenging with ...

Chargino pair production in $e^+e^-$ collisions [PDF]

open access: yesThe European Physical Journal C, 1999
Charginos $ _1^\pm$ are expected to be the lightest observable supersymmetric particles in many supersymmetric models. We present a procedure which will allow to determine the chargino mixing angles and, subsequently, the fundamental SUSY parameters $M_2, $ and $\tan $ by measurements of the total cross section and the spin correlations in $e^+e^-$

Supergravity Model of Inflation and Explaining IceCube HESE Data via PeV Dark Matter Decay

open access: yesAdvances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
We construct a unified model of inflation and PeV dark matter with an appropriate choice of no‐scale Kähler potential, superpotential, and gauge kinetic function in terms of MSSM fields and hidden sector Polonyi field. The model is consistent with the CMB observations and can explain the PeV neutrino flux observed at IceCube HESE.

Polarization of top and chargino from stop decay in natural SUSY

open access: yesPhysics Letters B, 2019
Top squark (stop) plays a crucial role in the naturalness of supersymmetry (SUSY) models, which has been extensively searched for in the LHC experiments.
