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)

Physics beyond the standard model [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2000 The Standard Model is in good shape, apart possibly from g_μ- 2 and some niggling doubts about the electroweak data. Something like a Higgs boson is required to provide particle masses, but theorists are actively considering alternatives. The problems of flavour, unification and quantum gravity will require physics beyond the Standard Model, and ...

Beyond the cosmological standard model [PDF]
Physics Reports, 2015 After a decade and a half of research motivated by the accelerating universe, theory and experiment have a reached a certain level of maturity. The development of theoretical models beyond , or smooth dark energy, often called modified gravity, has led to broader insights into a path forward, and a host of observational and experimental tests have ...

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 ...

PRESYMMETRY BEYOND THE STANDARD MODEL [PDF]
Modern Physics Letters A, 2009 We go beyond the Standard Model guided by presymmetry, the discrete electroweak quark–lepton symmetry hidden by topological effects which explain quark fractional charges as in condensed matter physics. We show that partners of the particles of the Standard Model and the discrete symmetry associated with this partnership appear as manifestations of a ...

Probing compressed dark sectors at 100 TeV in the dileptonic mono-Z channel
Journal of High Energy Physics, 2018 We examine the sensitivity at a future 100 TeV proton-proton collider to compressed dark sectors whose decay products are invisible due to below-threshold energies and/or small couplings to the Standard Model.

Minimal non-abelian supersymmetric Twin Higgs
Journal of High Energy Physics, 2017 We propose a minimal supersymmetric Twin Higgs model that can accommodate tuning of the electroweak scale for heavy stops better than 10% with high mediation scales of supersymmetry breaking.

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.

Interference effects in dilepton resonance searches for Z′ bosons and dark matter mediators
Journal of High Energy Physics, 2020 New Z′ gauge bosons arise in many extensions of the Standard Model and predict resonances in the dilepton invariant mass spectrum. Searches for such resonances therefore provide important constraints on many models of new physics, but the resulting ...
