Magnetic monopole meets primordial black hole: an extended analysis
Chen Zhang, Xin Zhang
We investigate gravitational capture of magnetic monopoles by primordial black holes (PBH) that evaporate before Big Bang Nucleosynthesis (BBN), a hypothetical process which was on…
Gravitational capture of magnetic monopoles by primordial black holes in the early universe
Chen Zhang, Xin Zhang
It is intriguing to ask whether the existence of primordial black holes (PBHs) in the early universe could significantly reduce the abundance of certain stable massive particles (S…
Quantum nucleation of up-down quark matter and astrophysical implications
Jing Ren, Chen Zhang
Quark matter with only and quarks (QM) might be the ground state of baryonic matter at large baryon number . With , this has no d…
The Techni-Pati-Salam Composite Higgs
Giacomo Cacciapaglia, Shahram Vatani, Chen Zhang
Composite Higgs models can be extended to the Planck scale by means of the partially unified partial compositeness (PUPC) framework. We present in detail the Techni-Pati-Salam mode…
Composite Higgs Meets Planck Scale: Partial Compositeness from Partial Unification
Giacomo Cacciapaglia, Shahram Vatani, Chen Zhang
Providing an Ultra-Violet completion valid up to the Planck scale is of paramount importance to validate the composite Higgs paradigm, at par with supersymmetry. We propose the fir…
Constraining CP-violating electron-gluonic operators
Kingman Cheung, Wai-Yee Keung, Ying-nan Mao +1
We present an analysis of constraints on two types of CP-odd electron-gluonic operators and from current and…
Phenomenology of A Little Higgs Pseudo-Axion
Kingman Cheung, Shi-Ping He, Ying-nan Mao +2
In models where the Higgs is realized as a pseudo-Nambu-Goldstone boson (pNGB) of some global symmetry breaking, there are often remaining pNGBs of some groups (called `pseu…
Simplest Little Higgs Revisited: Hidden Mass Relation, Unitarity and Naturalness
Kingman Cheung, Shi-Ping He, Ying-nan Mao +2
We analyze the scalar potential of the Simplest Little Higgs (SLH) model in an approach consistent with the spirit of continuum effective field theory (CEFT). By requiring correct…
On the vertex in the simplest Little Higgs Model
Shi-Ping He, Ying-nan Mao, Chen Zhang +1
The issue of deriving vertex in the simplest Little Higgs (SLH) model is revisited. Special attention is paid to the treatment of non-canonically-normalized scalar kinetic ma…
Quark matter may not be strange
Bob Holdom, Jing Ren, Chen Zhang
If quark matter is energetically favored over nuclear matter at zero temperature and pressure then it has long been expected to take the form of strange quark matter (SQM), with co…
Testing CP-Violation in the Scalar Sector at Future Colliders
Gang Li, Ying-nan Mao, Chen Zhang +1
We propose a {\em model-independent} method to test CP-violation in the scalar sector through measuring the inclusive cross sections of process…
A Loop-philic Pseudoscalar
Gang Li, Ying-nan Mao, Yi-Lei Tang +3
We construct a weakly-coupled renormalizable model to explain the $750\mbox{GeV}$ diphoton excess. The $750\mbox{GeV}$ resonance (denoted as ) is interpreted as a pseudosca…
Invisible Higgs Decay at the LHeC
Yi-Lei Tang, Chen Zhang, Shou-hua Zhu
The possibility that the 125 GeV Higgs boson may decay into invisible non-standard-model (non-SM) particles is theoretically and phenomenologically intriguing. In this letter we in…
Stable Asymptotically Free Extensions (SAFEs) of the Standard Model
Bob Holdom, Jing Ren, Chen Zhang
We consider possible extensions of the standard model that are not only completely asymptotically free, but are such that the UV fixed point is completely UV attractive. All coupli…
