SU(5/3) Superalgebra and Its Representations of Fundamental Particles
Chang-Ho Kim, Seung Kook Kim, Young-Jai Park
We study the lowest dimensional typical and atypical representations of SU(5/3) superalgebra as a possible unified gauge theory having a natural SU(5) subalgebra with SU(3) extra s…
Improved BFT embedding having chain-structure
Yong-Wan Kim, Ee Chang-Young, Seung-Kook Kim +1
We newly revisit the gauge non-invariant chiral Schwinger model with a=1 in view of the chain structure. As a result, we show that the Dirac brackets can be easily read off from th…
Symplectic Embedding of a Massive Vector-Tensor Theory with Topological Coupling
Yong-Wan Kim, Chang-Yeong Lee, Seung-Kook Kim +1
In the symplectic Lagrangian framework we newly embed an irreducible massive vector-tensor theory into a gauge invariant system, which has become reducible, by extending the config…
Complete BFT Embedding of Massive Theory with One- and Two-form Gauge Fields
Seung-Kook Kim, Yong-Wan Kim, Young-Jai Park
We study the constraint structure of the topologically massive theory with one- and two-form fields in the framework of Batalin-Fradkin-Tyutin embedding procedure. Through this ana…
Bifurcation of Periodic Instanton in Decay-Rate Transition
Hyun-Soo Min, Hungsoo Kim, D. K. Park +3
We investigate a bifurcation of periodic instanton in Euclidean action-temperature diagram in quantum mechanical models. It is analytically shown that multiple zero modes of fluctu…
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…
