Freeze-in dark matter from secret neutrino interactions
Journal of High Energy Physics, 2020 We investigate a simplified freeze-in dark-matter model in which the dark matter only interacts with the standard-model neutrinos via a light scalar.

Phenomenological analysis of multi-pseudoscalar mediated dark matter models
Journal of High Energy Physics, 2022 Non-minimal simplified extensions of the Standard Model have gained considerable currency in the context of dark matter searches at the LHC, since they predict enhanced mono-Higgs and mono-W/Z signatures over large parts of the parameter space.

Searches for Physics Beyond the Standard Model
Journal of Physics: Conference Series, 2011 Jefferson Lab has now demonstrated ablility to test the fundamental symmetries of nature, and thereby probe for new physics beyond the Standard Model. Here we review the tremendous advances in precision parity-violation measurements with CEBAF that enable searches for new physics.

Scalar electroweak multiplet dark matter
Journal of High Energy Physics, 2019 We revisit the theory and phenomenology of scalar electroweak multiplet thermal dark matter. We derive the most general, renormalizable scalar potential, assuming the presence of the Standard Model Higgs doublet, H, and an electroweak multiplet Φ of ...

Journal of High Energy Physics, 2017 We introduce a mirror copy of the ordinary fermions and Higgs scalars for embedding the SU(2) L × U(1) Y electroweak gauge symmetry into an SU(2) L × SU(2) R × U(1) B−L left-right gauge symmetry.

Journal of High Energy Physics, 2020 The Majoron, the Nambu-Goldstone boson of lepton number symmetry, is an interesting candidate for dark matter as it deeply connects the dark matter and neutrino physics.

High-scale leptogenesis with three-loop neutrino mass generation and dark matter
Journal of High Energy Physics, 2017 We demonstrate a common origin for high-scale leptogenesis and three-loop neutrino mass generation. Specifically we extend the standard model by two real singlet scalars, two singly charged scalars carrying different quantum numbers under certain global ...

An effective guide to beyond the Standard Model physics [PDF]
Journal of High Energy Physics, 2014 Effective Lagrangians with dimension-six operators are widely used to analyse Higgs and other electroweak data. We show how to build a basis of operators such that each operator corresponds to a coupling which is well measured or will be in the future. We choose a set of couplings such that the correspondence is one-to-one.
