On the Proof of Chiral Symmetry Breaking from Anomaly Matching in QCD-like Theories
Luca Ciambriello, Roberto Contino, Andrea Luzio +2
We critically reconsider the argument based on 't Hooft anomaly matching that aims at proving chiral symmetry breaking in confining four-dimensional QCD-like theories with …
Axion Free-kick Misalignment Mechanism
Ling-Xiao Xu, Seokhoon Yun
We propose an alternative scenario for the axion misalignment mechanism based on the nontrivial interplay between the axion and a light dilaton in the early universe. Dark matter a…
Grand Color Axion
Alessandro Valenti, Luca Vecchi, Ling-Xiao Xu
We present a model that solves the strong CP problem via an axion parametrically heavier than the standard one. Within this picture the Standard Model quarks are embedded into a la…
On the Derivation of Chiral Symmetry Breaking in QCD-like Theories and S-confining Theories
Andrea Luzio, Ling-Xiao Xu
Recent works argue that the pattern of chiral symmetry breaking in QCD-like theories can be derived from supersymmetric (SUSY) QCD with perturbation of anomaly-mediated SUSY breaki…
What can we learn from the total width of the Higgs boson?
Qing-Hong Cao, Hao-Lin Li, Ling-Xiao Xu +1
As one of the key properties of the Higgs boson, the Higgs total width is sensitive to global profile of the Higgs boson couplings, and thus new physics would modify the Higgs widt…
Softly shifting away from dark matter direct detection
Chuan-Yang Xing, Ling-Xiao Xu, Shou-hua Zhu
We propose soft breaking mechanism for dark matter (DM) shift symmetry in a class of composite dark matter models, where both DM and the Higgs boson arise as pseudo Nambu-Goldstone…
Determining the Shape of Higgs Potential at Future Colliders
Pankaj Agrawal, Debashis Saha, Ling-Xiao Xu +2
Although the Higgs boson has been discovered, its self-couplings are poorly constrained. This leaves the nature of the Higgs boson undetermined. Motivated by different Higgs potent…
Holographic Completion of Minimal Neutral Naturalness Model and Deconstruction
Ling-Xiao Xu, Jiang-Hao Yu, Shou-hua Zhu
We previously presented the minimal neutral naturalness model, in which neutral naturalness is realized with the minimal coset and the minimal field content in the color-neutral se…
EFTs meet Higgs Nonlinearity, Compositeness and (Neutral) Naturalness
Hao-Lin Li, Ling-Xiao Xu, Jiang-Hao Yu +1
Composite Higgs and neutral-naturalness models are popular scenarios in which the Higgs boson is a pseudo Nambu-Goldstone boson, and naturalness problem is addressed by composite t…
Resolving the degeneracy in top quark Yukawa coupling with Higgs pair production
Gang Li, Ling-Xiao Xu, Bin Yan +1
The top quark Yukawa coupling () can be modified by two dimension-six operators and with the corresponding Wilson coefficients and ,…
Signature of Pseudo Nambu-Goldstone Higgs boson in its Decay
Qing-Hong Cao, Ling-Xiao Xu, Bin Yan +1
If the Higgs boson is a pseudo Nambu-Goldstone boson (PNGB), the contact interaction induced by the invariants of the non-linear sigma model is free from i…
Minimal Neutral Naturalness Model
Ling-Xiao Xu, Jiang-Hao Yu, Shou-hua Zhu
We build a minimal neutral naturalness model in which the top partners are not charged under QCD, with a pseudo Goldstone Higgs arising from breaking. The color-neutr…
