Light Higgsino Decays as a Probe of the NMSSM
Bhaskar Dutta, Yu Gao, Bibhushan Shakya
In the Next-to Minimal Supersymmetric Standard Model (NMSSM), a sizable coupling between the singlet and Higgs fields can naturally accommodate the observed Higgs boson mass of…
Neutrino Masses and Sterile Neutrino Dark Matter from the PeV Scale
Samuel B. Roland, Bibhushan Shakya, James D. Wells
We show that active neutrino masses and a keV-GeV mass sterile neutrino dark matter candidate can result from a modified, low energy seesaw mechanism if right-handed neutrinos are…
Dark Matter at the Pseudoscalar Higgs Resonance in the pMSSM and SUSY GUTs
Archana Anandakrishnan, Bibhushan Shakya, Kuver Sinha
We study dark matter at the MSSM pseudoscalar Higgs resonance (A-funnel), which is one of the few remaining MSSM thermal dark matter candidates in the GeV range safe fro…
Probable or Improbable Universe? Correlating Electroweak Vacuum Instability with the Scale of Inflation
Anson Hook, John Kearney, Bibhushan Shakya +1
Measurements of the Higgs boson and top quark masses indicate that the Standard Model Higgs potential becomes unstable around GeV. This instability is cosmologic…
