Electroweak symmetry breaking from unparticles
Jong-Phil Lee
A new type of scalar potential inspired by unparticles is proposed for the electroweak symmetry breaking. The interaction between the standard model fields and unparticle sector is…
Unparticles and holography
Jong-Phil Lee
We construct the holographic dual theory of unparticles. The Randall-Sundrum type hard wall model is shown to produce deconstructing particles, whose spectrum has a finite mass gap…
to light meson form factors with end-point cutoff
Jong-Phil Lee
Decay form factors of to light pseudoscalar () and vector () mesons are analyzed with the momentum cutoff near end point. The cutoff is caused by possible Cherenkov gluon…
Heavy quarkonium in a holographic QCD model
Youngman Kim, Jong-Phil Lee, Su Houng Lee
Encouraged by recent developments in AdS/QCD models for light quark system, we study heavy quarkonium in the framework of the AdS/QCD models. We calculate the masses of v…
Taming the end-point singularities in heavy-to-light decays
Jong-Phil Lee
It is argued that there is a fundamental momentum cutoff in heavy-to-light transitions, which is caused by possible Cherenkov gluon radiation when an energetic light parton travels…
Heavy-to-light form factors of B decays at large recoil
Jong-Phil Lee
The form factors of decays are analyzed using the light-cone sum rules in the framework of the soft-collinear effective theory (SCET). We establish the sum rules for the…
