1. Universal Imprints of a Pseudo-Nambu-Goldstone Higgs Boson / Liu, Da ; Low, Ian ; Yin, Zhewei
A large class of models addressing the electroweak naturalness problem postulates the existence of new spontaneously broken global symmetries above the weak scale. [...]

2. The infrared structure of Nambu-Goldstone bosons / Low, Ian ; Yin, Zhewei
The construction of effective actions for Nambu-Goldstone bosons, and the nonlinear sigma model, usually requires a target coset space G / H . [...]

3. Broadening dark matter searches at the LHC: mono-X versus darkonium channels / Krovi, Anirudh ; Low, Ian ; Zhang, Yue
Current searches for dark matter at the LHC focus on mono-X signatures: the production of dark matter in association with a Standard Model (SM) particle. [...]

4. Top-philic Z ′ forces at the LHC / Fox, Patrick ; Low, Ian ; Zhang, Yue
Despite extensive searches for an additional neutral massive gauge boson at the LHC, a Z ′ at the weak scale could still be present if its couplings to the first two generations of quarks are suppressed, in which case the production in hadron colliders relies on tree-level processes in association with heavy flavors or one-loop processes in association with a jet. [...]

5. Ward Identity and Scattering Amplitudes for Nonlinear Sigma Models / Low, Ian ; Yin, Zhewei
We present a Ward identity for nonlinear sigma models using generalized nonlinear shift symmetries, without introducing current algebra or coset space. [...]

6. Testing naturalness at 100 TeV / Chen, Chuan-Ren ; Hajer, Jan ; Liu, Tao ; Low, Ian ; et al
Solutions to the electroweak hierarchy problem typically introduce a new symmetry to stabilize the quadratic ultraviolet sensitivity in the self-energy of the Higgs boson. [...]

7. Same-sign dilepton excesses and vector-like quarks / Chen, Chuan-Ren ; Cheng, Hsin-Chia ; Low, Ian
Multiple analyses from ATLAS and CMS collaborations, including searches for ttH production, supersymmetric particles and vector-like quarks, observed excesses in the same-sign dilepton channel containing b -jets and missing transverse energy in the LHC Run 1 data. [...]

8. Impersonating the Standard Model Higgs boson: alignment without decoupling / Marcela Carena ; Ian Low ; Nausheen R. Shah ; Carlos E.M. Wagner
In models with an extended Higgs sector there exists an alignment limit, in which the lightest CP-even Higgs boson mimics the Standard Model Higgs. [...]
