Soft Wilson lines in soft-collinear effective theory

Junegone Chay, Chul Kim, Yeong Gyun Kim +1

The effects of the soft gluon emission in hard scattering processes at the phase boundary are resummed in the soft-collinear effective theory (SCET). In SCET, the soft gluon emissi…

Strong phase shifts and color-suppressed tree amplitudes in B -> D K^(*) and B -> D pi, D rho decays

C. S. Kim, Sechul Oh, Chaehyun Yu

We analyze the decay processes B \to DK, DK^*, Dπ, and Dρin a model-independent way. Using the quark diagram approach, we determine the magnitudes of the relevant amplitudes and th…

Parity of (1540) from QCD sum rules

Su Houng Lee, Hungchong Kim, Youngshin Kwon

The QCD sum rule for the pentaquark , first analyzed by Sugiyama, Doi and Oka, is reanalyzed with a phenomenological side that explicitly includes the contribution from the tw…

Time dependent CP asymmetry in decay to probe the origin of CP violation

C. S. Kim, Yeong Gyun Kim, Kang Young Lee

Since the CP violation in the system has been investigated up to now only through processes related to the -- mixing, urgently required is new way of study for the…

Neutral Higgs Boson Production and CP Violation at LC

Kang Young Lee, C. S. Kim, Chaehyun Yu

We study the neutral Higgs boson production at the linear collider in the two Higgs doublet model with the CP violation. The CP-even and CP-odd scalars are mixed in this…
