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.

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 ...

Journal 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.

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

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

Modeling General Asymptotic Calabi–Yau Periods
Fortschritte der Physik, EarlyView.Abstract In the quest to uncovering the fundamental structures that underlie some of the asymptotic Swampland conjectures the authors initiate the general study of asymptotic period vectors of Calabi–Yau manifolds. The strategy is to exploit the constraints imposed by completeness, symmetry, and positivity, which are formalized in asymptotic Hodge ...

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