Constraining parameter space in type-II two-Higgs doublet model in light of a 126 GeV Higgs boson
H. S. Cheon, Sin Kyu Kang
We explore the implications of a 126 GeV Higgs boson indicated by the recent LHC results for two-Higgs doublet model (2HDM). Identifying the 126 GeV Higgs boson as either the light…
Dark matter signals and cosmic ray anomalies in an extended seesaw model
H. S. Cheon, Sin Kyu Kang, C. S. Kim
An extended seesaw model proposed to achieve low scale leptogenesis can resolve the excess positron and electron fluxes observed from PAMELA, ATIC and/or Fermi-LAT, and simultaneou…
Doubly Coexisting Dark Matter Candidates in an Extended Seesaw Model
H. S. Cheon, Sin Kyu Kang, C. S. Kim
We examine how a scenario of coexisting two-particle dark mater can be realized in the extended seesaw model, which we have proposed previously to accommodate small neutrino masses…
Low Scale Leptogenesis and Dark Matter Candidates in an Extended Seesaw Model
H. Sung Cheon, Sin Kyu Kang, C. S. Kim
We consider a variant of seesaw mechanism by introducing extra singlet neutrinos and singlet scalar boson, and show how low scale leptogenesis is successfully realized in this scen…
