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.

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 ...

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.

Beyond the standard model with the LHC [PDF]
Nature, 2007 Whether or not the Large Hadron Collider reveals the long-awaited Higgs particle, it is likely to lead to discoveries that add to, or challenge, the standard model of particle physics. Data produced will be pored over for any evidence of supersymmetric partners for the existing denizens of the particle 'zoo' and for the curled-up extra dimensions ...

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.
