Negative modes and decay-rate transition
Soo-Young Lee, Hungsoo Kim, D. K. Park +1
We investigate a relationship between the number of the negative modes around periodic instanton solution and the type of the decay-rate transition. It is shown that for the case o…
Effect of dissipation on the decay-rate phase transition
Soo-Young lee, Hungsoo Kim, D. K. Park +2
A general condition for sharp transition of decay rate from quantum to thermal regimes is derived in dissipative tunneling models when position dependent mass is involved. It is sh…
Critical value of symmetry breaking parameter in the phase transition of decay rate
Hungsoo Kim, Soo-Young Lee, Sahng-Kyoon Yoo +2
Phase transition of decay rate from quantum tunneling to thermal activity regimes is investigated in (3+1)-dimensional field theories with symmetry breaking term . By applying…
Polarization in B_c -> J/ψmu nu
Myoung-Taek Choi, Jae Kwan Kim
We study the polarization of the J/ψmeson of the B_c -> J/ψmu nu decay process, followed by J/ψ-> mu+ mu-, with the help of the heavy-quark spin symmetry formalism (HQSS). We adapt…
Determination of from the polarization of vector meson in the semileptonic decay of and meson
Myoung-Taek Choi, Jae Kwan Kim
Since the degree of polarization of the vector particle in semileptonic decay strongly influences the decay width of the particles, it can be used as a measure of CKM matrix elemen…
Phenomenological Implications of the Topflavor Model
Jong Chul Lee, Kang Young Lee, Jae Kwan Kim
We explore phenomenologies of the topflavour model for the LEP experiment at scale and the atomic parity violation (APV) experiment in the atoms at low energies. Imp…
