2HDM Portal Dark Matter: LHC data and the Fermi-LAT 135 GeV Line
Yang Bai, Vernon Barger, Lisa L. Everett +1
We study a two Higgs doublet model augmented by a scalar dark matter particle that provides an excellent fit to the LHC Higgs data and the Fermi-LAT 135 GeV line. The heavy CP-even…
Dichromatic Dark Matter
Yang Bai, Meng Su, Yue Zhao
Both the robust INTEGRAL 511 keV gamma-ray line and the recent tentative hint of the 135 GeV gamma-ray line from Fermi-LAT have similar signal morphologies, and may be produced fro…
Large N (=3) Neutrinos and Random Matrix Theory
Yang Bai, Gonzalo Torroba
The large N limit has been successfully applied to QCD, leading to qualitatively correct results even for N=3. In this work, we propose to treat the number N=3 of Standard Model ge…
The 2HDM-X and Large Hadron Collider Data
Yang Bai, Vernon Barger, Lisa L. Everett +1
We study the consistency of two Higgs doublet models in light of the new bosonic particle discovery at the LHC. We work within a general setup that we call the 2HDM-X, in which the…
Gamma Lines without a Continuum: Thermal Models for the Fermi-LAT 130 GeV Gamma Line
Yang Bai, Jessie Shelton
Recent claims of a line in the Fermi-LAT photon spectrum at 130 GeV are suggestive of dark matter annihilation in the galactic center and other dark matter-dominated regions. If th…
Searches with Mono-Leptons
Yang Bai, Tim M. P. Tait
We explore the implications of the mono-lepton plus missing transverse energy signature at the LHC, and point out its significance on understanding how dark matter interacts with q…
