Comparatively light extra Higgs states as signature of SUSY SO(10) GUTs with 3rd family Yukawa unification

Journal of High Energy Physics, 2020
We study 3rd family Yukawa unification in the context of supersymmetric (SUSY) SO (10) GUTs and SO(10)-motivated boundary conditions for the SUSY-breaking soft terms.

Interpreting the electron EDM constraint

Journal of High Energy Physics, 2019
The ACME collaboration has recently announced a new constraint on the electron EDM, |d e | < 1.1 × 10−29 e cm, from measurements of the ThO molecule. This is a powerful constraint on CP-violating new physics: even new physics generating the EDM at two ...

ATLAS Z Excess in Minimal Supersymmetric Standard Model [PDF]

, 2015
Recently the ATLAS collaboration reported a 3 sigma excess in the search for the events containing a dilepton pair from a Z boson and large missing transverse energy.

Very constrained minimal supersymmetric standard models [PDF]

Physical Review D, 2004
We consider very constrained versions of the minimal supersymmetric extension of the Standard Model (VCMSSMs) which, in addition to constraining the scalar masses m_0 and gaugino masses m_{1/2} to be universal at some input scale, impose relations between the trilinear and bilinear soft supersymmetry breaking parameters A_0 and B_0. These relations may

Charged fermions below 100 GeV

Journal of High Energy Physics, 2018
How light can a fermion be if it has unit electric charge? We revisit the lore that LEP robustly excludes charged fermions lighter than about 100 GeV.

Constrained Next-to-Minimal Supersymmetric Standard Model [PDF]

Physical Review Letters, 2008
We consider the fully constrained version of the next-to-minimal supersymmetric extension of the standard model (cNMSSM) in which a singlet Higgs superfield is added to the two doublets that are present in the minimal extension (MSSM). Assuming universal boundary conditions at a high scale for the soft supersymmetry-breaking gaugino, sfermion and Higgs

Probing new electroweak states via precision measurements at the LHC and future colliders

Journal of High Energy Physics, 2019
Several new physics scenarios, motivated e.g. by dark matter, feature new electroweakly charged states where the lightest particle in the multiplet is stable and neutral.

Time-delayed electrons from neutral currents at the LHC

Journal of High Energy Physics, 2021
We investigate long-lived particles (LLPs) produced in pair from neutral currents and decaying into a displaced electron plus two jets at the LHC, utilizing the proposed minimum ionizing particle timing detector at CMS. We study two benchmark models: the

R-invariant New Inflation Model vs Supersymmetric Standard Model [PDF]

, 2007
We revisit the implications of the R-invariant New Inflation model to the supersymmetric standard model in light of recent discussion of gravitino production processes by the decay of the inflaton or the supersymmetry breaking field.
