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.

Indirect probe of electroweakly interacting particles at the high-luminosity Large Hadron Collider
Journal of High Energy Physics, 2018 Many extensions of the standard model (SM) involve new massive particles charged under the electroweak gauge symmetry. The electroweakly interacting new particles affect various SM processes through radiative corrections.

Impact of an extra gauge interaction on naturalness of supersymmetry
Journal of High Energy Physics, 2018 It is pointed out that in supersymmetric models with a new gauge symmetry under which the Higgs is charged, the fine-tuning of the electroweak symmetry breaking is relaxed due to suppression of the top Yukawa coupling at higher scales by a new large ...

Constraining the gauge and scalar sectors of the doublet left-right symmetric model
Journal of High Energy Physics, 2020 We consider a left-right symmetric extension of the Standard Model where the spontaneous breakdown of the left-right symmetry is triggered by doublets. The electroweak ρ parameter is protected from large corrections in this Doublet Left-Right Model (DLRM)

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 ...

Jet substructure from dark sector showers
Journal of High Energy Physics, 2020 We examine the robustness of collider phenomenology predictions for a dark sector scenario with QCD-like properties. Pair production of dark quarks at the LHC can result in a wide variety of signatures, depending on the details of the new physics model ...

Beyond the Standard Model [PDF]
, 2015 We introduce aspects of physics beyond the Standard Model focusing on supersymmetry, extra dimensions, and a composite Higgs as solutions to the Hierarchy problem.

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.

HERA Physics Beyond the Standard Model [PDF]
, 1999 The prospects of physics beyond the standard model in deep inelastic scattering are reviewed, emphasizing some scenarios which attained attention after the observation of an excess of events with large momentum transfer at HERA.Comment: 8 pages, LaTeX ...

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.
