Chiral orbital-angular-momentum in the surface states of Bi2Se3
Seung Ryong Park, Jinhee Han, Chul Kim +11
Locking of the spin of a quasi-particle to its momentum in split bands of on the surfaces of metals and topological insulators (TIs) is understood in terms of Rashba effect where a…
Octetonium at the LHC
Chul Kim, Thomas Mehen
Several models of new physics, such as grand unified theories, Pati-Salam models, chiral color models, etc., predict the existence of an doublet of color-octet scalars (C…
Electron Removal Self Energy and its application to Ca2CuO2Cl2
Chul Kim, S. R. Park, C. S. Leem +5
We propose using the self energy defined for the electron removal Green's function. Starting from the electron removal Green's function, we obtained expressions for the removal sel…
Collinear effective theory at subleading order and its application to heavy-light currents
Junegone Chay, Chul Kim
We consider a collinear effective theory of highly energetic quarks with energy E, interacting with collinear and soft gluons by integrating out collinear degrees of freedom to sub…
Consequences of symmetries in renormalizing collinear effective theory
Junegone Chay, Chul Kim
We consider effects of symmetries on renormalization properties of the collinear effective theory. We investigate which types of operators are possible in the effective theory sati…
Symmetries in collinear effective theory
Junegone Chay, Chul Kim
We consider various symmetries present in the collinear effective theory and their implications. There are collinear, soft and ultrasoft gauge symmetries and we discuss transformat…
