Towards Yukawa unification in a strongly Yukawa coupling model
Keyan Yang
For strong enough Yukawa coupling the electroweak standard model fermion finds it energetically advantageous to transform itself into a bound state in the hedgehog background of Hi…

Fermion number violation in heavy fermion decay
Keyan Yang
The presence of a heavy fermion doublet of fourth generation in the standard model would lead to a anomalous decay with fermion number non-conservation. The anomalous decay path in…
