Higgs-Precision Constraints on Colored Naturalness
, 2017 The presence of weak-scale colored top partners is among the simplest solutions to the Higgs hierarchy problem and allows for a natural electroweak scale.

Chiral Perturbation Theory with an Isosinglet Scalar [PDF]
, 2018 We present an extension of chiral perturbation theory that explicitly includes an isosinglet scalar in the Lagrangian. The dynamical effects from the scalar state is of phenomenological relevance in theories where the mass of the isosinglet scalar is ...

Solutions to axion electromagnetodynamics and new search strategies of sub-μeV axion
Journal of High Energy Physics, 2023 The Witten effect implies the electromagnetic interactions between axions and magnetic monopoles, and the quantum electromagnetodynamics (QEMD) properly describes interactions of electric charges, magnetic charges and photons.

Heavy Neutral Gauge Bosons at the LHC in an Extended MSSM
, 2012 Searching for heavy neutral gauge bosons Z', predicted in extensions of the Standard Model based on a U(1)' gauge symmetry, is one of the challenging objectives of the experiments carried out at the Large Hadron Collider.

, 2018 The standard model of particle physics is an extremely successful theory of fundamental interactions, but it has many known limitations. It is therefore widely believed to be an effective field theory that describes interactions near the TeV scale.

Potential for probing three-body decays of Long-Lived Particles with MATHUSLA
, 2018 Several extensions of the Standard Model predict the existence of Long-Lived Neutral Particles (LLNPs) with masses in the multi-GeV range and decay lengths of O(100 m) or longer.

Scalar resonances near 650 and 95 GeV in the GNMSSM with correct dark matter relic abundance
Journal of High Energy PhysicsRecent CMS analyses report an excess in the diphoton-plus- b b ¯ $$ b\overline{b} $$ channel, indicative of a heavy resonance around 650 GeV decaying into a Standard Model (SM)-like Higgs boson and a lighter scalar near 95 GeV.

Collider Signatures of the N=3 Lee-Wick Standard Model
, 2012 Inspired by the Lee-Wick higher-derivative approach to quantum field theory, Grinstein, O'Connell, and Wise have illustrated the utility of introducing into the Standard Model negative-norm states that cancel quadratic divergences in loop diagrams, thus ...
