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 ...

Supersymmetric standard models on D-branes [PDF]
Physics Letters B, 2001 Type IIB superstring models with the standard model gauge group on D3-branes and with massless matter associated with open strings joining D3-branes to D3-branes or D3-branes to ${\rm D}7_3$-branes are studied. Models with gauge coupling constant unification at an intermediate scale between about $10^{10}$ and $10^{12}$GeV and consistency with the ...

Single charged Higgs boson production at next generation linear colliders [PDF]
, 2000 We study the single production of charged Higgs bosons in e+e- collisions, chiefly in the Minimal Supersymmetric Standard Model. Our analysis complements foregoing studies of the pair production channel especially in regions where the kinematic ...

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.

HERWIG 6: an event generator for Hadron emission reactions with interfering gluons (including supersymmetric processes) [PDF]
, 2000 HERWIG is a general-purpose Monte Carlo event generator, which includes the simulation of hard lepton-lepton, lepton-hadron and hadron-hadron scattering and soft hadron-hadron collisions in one package. It uses the parton-shower approach for initial- and

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.

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 ...

Time-delayed electrons from neutral currents at the LHC
Journal of High Energy Physics, 2021 We investigate long-lived particles (LLPs) produced in pair from neutral currents and decaying into a displaced electron plus two jets at the LHC, utilizing the proposed minimum ionizing particle timing detector at CMS. We study two benchmark models: 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.
