My research area is theoretical particle physics phenomenology, primarily on probing fundamental nature beyond the Standard Model from collider experiments, dark matter detection, astrophysical/cosmological observations and various others.


Postdoc positions at CTP-SNU available in 2018:
  Outstanding researchers on particle physics phenomenology, cosmology, dark matter and gravitational wave are welcome to apply. 



Research Interests:

My research publication can be found at INSPIRES-HEP, ("ea jung, sunghoon") or at Google Scholar.

1. Higgs physics:  The fact that the Higgs boson is SM-like only strengthens a null-hypothesis of physics beyond the SM. But we know new physics exists. How can we learn them from the Higgs boson? 
  - Improved and model-independent formalism and strategy for Higgs precision analysis: 
  - (Heavy) Higgs lineshapes (including never-seen pure resonance dips and nothingness):  
  - Radiative generation of the Higgs potential: 
  - Necessary signals of Future SUSY from the Higgs and Higgsino:
  - Abelian Higgs sector (Higgs portal and kinetic mixing):
  
2. Supersymmetry at (future) colliders:  The absence of SUSY below TeV scale at LHC is very disappointing. But multi-TeV (or PeV) SUSY can not only exist equally well, but also highly motivated and still very satisfactory in many senses. How can we discover or rule out such Future SUSY? 
  - Prospects for Electroweakino and Gluino Discovery at a 100 TeV Hadron Collider:
  - Higgs and Higgsino signals in future SUSY:
  - Stoponium signals:

3. Gravitational wave:  Needless to say, today is GW era. What can we do and what do we need for it? 
  - Localizing mid-frequency GWs on the sky
  - b

4. Dark matter and astrophysical signals:  Dark matter is another mystery. We know it exists but we never saw it and don't know what it is. 
  - Very Degenerate Higgsino Dark Matter Annihilation Signals:

5. Top quarks and Effective field theories:  Why is the top quark as heavy as the electroweak scale? Does it contain clues of the nature of electroweak symmetry breaking?
  - Renormalization Group-Induced Phenomena of Top Pairs From Four-Quark Effective Operators:
  - Correlation of Top Asymmetries: Loop Versus Tree Origins:
  - Top Quark Forward-Backward Asymmetry from New t-channel Physics:

6. Displaced decays of SUSY:  Can SUSY hide behind displaced decays? 
  - Displaced signals from the Higgsino, Axino, Gravitino, and very light charginos
