A Solution to the Strong CP Problem
Marcela Carena, Da Liu, Jia Liu +3
We present a new solution to the strong CP problem in which the imaginary component of the up quark mass, , acquires a tiny, but non-vanishing value. This is achi…

A Golden Probe of Nonlinear Higgs Dynamics
Da Liu, Ian Low, Roberto Vega-Morales
The most salient generic feature of a composite Higgs boson resides in the nonlinearity of its dynamics, which arises from degenerate vacua associated with the pseudo-Nambu-Goldsto…

Broad composite resonances and their signals at the LHC
Da Liu, Lian-Tao Wang, Ke-Pan Xie
We explore the possibility that the left-handed third generation quark doublet is fully composite in composite Higgs models. The signature of the model is the presence of bro…
