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

Electric Dipole Moments in the Generic Supersymmetric Standard Model [PDF]

, 2001
The generic supersymmetric standard model is a model built from a supersymmetrized standard model field spectrum the gauge symmetries only. The popular minimal supersymmetric standard model differs from the generic version in having R-parity imposed by ...

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.

A Warped Supersymmetric Standard Model [PDF]

, 2001
We study the breaking of supersymmetry in five-dimensional (5d) warped spaces, using the Randall-Sundrum model as a prototype. In particular, we present a supersymmetry-breaking mechanism which has a geometrical origin, and consists of imposing different

Dark matter blind spots at one-loop

Journal of High Energy Physics, 2019
We evaluate the impact of one-loop electroweak corrections to the spin-independent dark matter (DM) scattering cross-section with nucleons (σ SI), in models with a so-called blind spot for direct detection, where the leading-order prediction for the ...

Indirect probe of electroweak-interacting particles with mono-lepton signatures at hadron colliders

Journal of High Energy Physics, 2019
Electroweak-interacting massive particles (EWIMPs) exist in a broad class of new physics models beyond the Standard Model. Searching for such particles is one of most primary goal at the LHC and future colliders.

Proposal for a Supersymmetric Standard Model

, 2005
The fact that neutrinos are massive suggests that the minimal supersymmetric standard model (MSSM) might be extended in order to include three gauge-singlet neutrino superfields with Yukawa couplings of the type $H_2 L \nu^c$.

Prospects for Sneutrino Dark Matter in the BLSSM [PDF]

, 2018
The $(B-L)$ Supersymmetric Standard Model (BLSSM) motivates several Dark Matter (DM) candidates beyond the Minimally Supersymmetric Standard Model (MSSM).

Spontaneous CP violation and horizontal symmetry in the MSSM: toward lepton flavor naturalness

Journal of High Energy Physics, 2021
We study the contributions of supersymmetric models with a U(1) horizontal symmetry and only spontaneous CP breaking to various lepton flavor observables, such as μ → eγ and the electron electric dipole moment. We show that both a horizontal symmetry and
