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.

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.

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)

CP Violation Beyond the Standard Model [PDF]

, 2003
I review CP-violating signals of physics beyond the standard model in the B system. I examine the prospects for finding these effects at future colliders, with an emphasis on hadron machines.Comment: 11 pages, plain latex, no figures.

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 ...

b Physics Beyond the Standard Model [PDF]

, 2002
I review the signals for New Physics in CP-violating measurements in B and Lambda_b decays. I also discuss ways of identifying this New Physics, should such a signal be found.Comment: 10 pages, LaTeX, 1 figure, ps file included.

Neutrino decoupling beyond the Standard Model: CMB constraints on the Dark Matter mass with a fast and precise Neff evaluation [PDF]

Journal of Cosmology and Astroparticle Physics, 2018
The number of effective relativistic neutrino species represents a fundamental probe of the thermal history of the early Universe, and as such of the Standard Model of Particle Physics.

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.
