Journal of High Energy Physics, 2019 We present our calculation of the two-loop corrections of O $$ \mathcal{O} $$ ( α t 2 $$ {\alpha}_t^2 $$ ) to the neutral Higgs boson masses of the CP-violating Next-to-Minimal Supersymmetric extension of the Standard Model (NMSSM).

Journal of High Energy Physics, 2021 Minimal gauged U 1 L μ − L τ $$ \mathrm{U}{(1)}_{L_{\mu }-{L}_{\tau }} $$ models can provide for an additional source for the muon anomalous magnetic moment however it is difficult to accommodate the discrepancy in the electron magnetic moment in tandem.

Confronting the coloured sector of the MRSSM with LHC data
Journal of High Energy Physics, 2019 R-symmetry leads to a distinct low energy realisation of SUSY with a signicantly modified colour-charged sector featuring a Dirac gluino and scalar colour octets (sgluons). In the present work we recast results from LHC BSM searches to discuss the impact

Sneutrino DM in the NMSSM with inverse seesaw mechanism
Journal of High Energy Physics, 2017 In supersymmetric theories like the Next-to-Minimal Supersymmetric Standard Model (NMSSM), the lightest neutralino with bino or singlino as its dominant component is customarily taken as dark matter (DM) candidate.

Phenomenology of supersymmetry with scalar sequestering [PDF]
Physical Review D, 2009 The defining feature of scalar sequestering is that the minimal supersymmetric standard model squark and slepton masses as well as all entries of the scalar Higgs mass matrix vanish at some high scale. This ultraviolet boundary condition--scalar masses vanish while gaugino and Higgsino masses are unsuppressed--is independent of the supersymmetry ...

Slepton pair production at the LHC in NLO+NLL with resummation-improved parton densities
Journal of High Energy Physics, 2018 Novel PDFs taking into account resummation-improved matrix elements, albeit only in the fit of a reduced data set, allow for consistent NLO+NLL calculations of slepton pair production at the LHC.

Non-minimal flavour violation in A 4 × SU(5) SUSY GUTs with smuon assisted dark matter
Journal of High Energy Physics, 2019 We study CP-conserving non-minimal flavour violation in A 4 × SU(5) inspired Supersymmetric Grand Unified Theories (GUTs), focussing on the regions of parameter space where dark matter is successfully accommodated due to a light right-handed smuon a few ...

Journal of High Energy Physics, 2017 The LUX experiment has recently set very strong constraints on spin-independent interactions of WIMP with nuclei. These null results can be accommodated in NMSSM provided that the effective spin-independent coupling of the LSP to nucleons is suppressed ...

Singularity variables for missing energy event kinematics
Journal of High Energy Physics, 2020 We discuss singularity variables which are properly suited for analyzing the kinematics of events with missing transverse energy at the LHC. We consider six of the simplest event topologies encountered in studies of leptonic W -bosons and top quarks, as ...
