Gauge-invariant Lagrangian of the soft-collinear effective theory and its application to soft-collinear currents
Junegone Chay, Chul Kim
We construct the soft-collinear effective Lagrangian which is manifestly gauge invariant order by order. Field redefinitions of collinear gauge fields and a proper decomposition of…
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…
Analysis of the QCD-improved factorization in B -> J/ψK
Junegone Chay, Chul Kim
We consider the exclusive decay using the QCD-improved factorization method in the heavy quark limit. It is shown that the decay amplitude is factorizable in this limit…
