Dark matter blind spots at one-loop

open access: yesJournal 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 ...

Supersymmetric Standard Model from the Heterotic String [PDF]

open access: yesPhysical Review Letters, 2006
We present a Z_6 orbifold compactification of the E_8xE_8 heterotic string which leads to the (supersymmetric) Standard Model gauge group and matter content. The quarks and leptons appear as three 16-plets of SO(10), whereas the Higgs fields do not form complete SO(10) multiplets.

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

open access: yesJournal 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.

Duality of a Supersymmetric Standard Model [PDF]

open access: yes, 1995
We examine a dual theory of a Supersymmetric Standard Model(SSM) in terms of an $SU(3)_C$ gauge group. In this scenario, it is naturally understood that at least one quark (the top quark) should be heavy, i.e., almost the same order as the weak scale ...

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

open access: yes, 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 ...

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

open access: yesJournal 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

Long-lived biνo at the LHC

open access: yesJournal of High Energy Physics, 2021
We examine the detection prospects for a long-lived biνo, a pseudo-Dirac bino which is responsible for neutrino masses, at the LHC and at dedicated long-lived particle detectors.

Detectable dimension-6 proton decay in SUSY SO(10) GUT at Hyper-Kamiokande

open access: yesJournal of High Energy Physics, 2019
In the minimal SUSY SU(5) GUT with O(1) TeV SUSY particles and O(1) or below self-coupling for the GUT-breaking Higgs field, the width of the dimension-6 proton decay is suppressed below the reach of Hyper-Kamiokande.

Same sign trilepton as signature of charged Higgs in two Higgs doublet model

open access: yesJournal of High Energy Physics, 2022
We explored the prospect of looking for a fermiophobic charged Higgs (H ±) via the same sign trilepton signal at the LHC. A fermiophobic scenario appears in the type-I two Higgs doublet model where the coupling of the H ± with the Standard Model fermions
