Light stops and fine-tuning in MSSM

European Physical Journal C: Particles and Fields, 2018
We discuss the fine-tuning issue within the MSSM framework. Following the idea that the fine-tuning can measure effects of some missing mechanism, we impose non-universal gaugino masses at the GUT scale, and explore the low scale implications. We realize

$SU(2)\otimes SU(2)$ Gauge Extensions of the MSSM Revisited

, 2013
We study an extension of the Minimal Supersymmetric Standard Model with a gauge group $SU(2)_1\otimes SU(2)_2$ breaking to $SU(2)_L$. The extra wino has an enhanced gauge coupling to the SM-like Higgs boson and, if light, has a relevant impact on the ...

Searches for direct stop production in events with two leptons in √s = 8 TeV pp collisions using 20 fb−1 of ATLAS data

EPJ Web of Conferences, 2014
Three searches for direct top squark pair production are presented. They target different decay modes, each with two leptons (electrons or muons) in the final state.

Probing electroweakly interacting massive particles with Drell–Yan process at 100 TeV hadron colliders

Physics Letters B, 2019
There are many models beyond the standard model which include electroweakly interacting massive particles (EWIMPs), often in the context of the dark matter.

Supersymmetric Models and CP violation in B decays

, 2005
In this talk CP violation in the supersymmetric models, and especially in B-decays is discussed. We review our analysis of the supersymmetric contributions to the mixing CP asymmetries of $B\to \phi K_S$ and $B\to \eta^{\prime} K_S$ processes.

Comparative Study of CP Asymmetries in Supersymmetric Models

, 2004
We systematically analyze the supersymmetric contributions to the mixing CP asymmetries and branching ratios of B -> Phi K(S) and B -> eta(prime) K(S) processes.
