Interplay between Fermi gamma-ray lines and collider searches
Hyun Min Lee, Myeonghun Park, Veronica Sanz
We explore the interplay between lines in the gamma-ray spectrum and LHC searches involving missing energy and photons. As an example, we consider a singlet Dirac fermion dark matt…
Singlet Assisted Vacuum Stability and the Higgs to Diphoton Rate
Brian Batell, Sunghoon Jung, Hyun Min Lee
Light, electrically charged vector-like `leptons' with order one Yukawa couplings can enhance the Higgs to diphoton decay rate, as is suggested by measurements of the signal streng…
Axion-mediated dark matter and Higgs diphoton signal
Hyun Min Lee, Myeonghun Park, Wan-Il Park
We consider axion-mediated dark matter models motivated by Fermi gamma ray line at 130 GeV, where anomaly interactions of an axion-like scalar mediate a singlet Dirac fermion dark…
Vacuum Stability, Perturbativity, EWPD and Higgs-to-diphoton rate in Type II Seesaw Models
Eung Jin Chun, Hyun Min Lee, Pankaj Sharma
We study constraints from perturbativity and vacuum stability as well as the EWPD in the type II seesaw model. As a result, we can put stringent limits on the Higgs triplet couplin…
Hitting sbottom in natural SUSY
Hyun Min Lee, Veronica Sanz, Michael Trott
We compare the experimental prospects of direct stop and sbottom pair production searches at the LHC. Such searches for stops are of great interest as they directly probe for state…
Fermi Gamma Ray Line at 130 GeV from Axion-Mediated Dark Matter
Hyun Min Lee, Myeonghun Park, Wan-Il Park
We consider a singlet Dirac fermion with Peccei-Quinn(PQ) symmetry as dark matter. A singlet complex scalar is introduced to mediate between dark matter and the SM through Higgs po…
