Phenomenology of Particle Production and Propagation in String-Motivated Canonical Noncommutative Spacetime
Giovanni Amelino-Camelia, Luisa Doplicher, Soonkeon Nam +1
We outline a phenomenological programme for the search of effects induced by (string-motivated) canonical noncommutative spacetime. The tests we propose are based, in analogy with…
Superpartner Solutions of a BPS Monopole in Noncommutative Space
Euy Soo Na
We construct U(2) BPS monopole superpartner solutions in N=2 non-commutative super Yang-Mills theory. Calculation to the second order in the noncommutative parameter shows that…
Orientifold in Conifold and Quantum Deformation
Changhyun Ahn, Soonkeon Nam, Sang-Jin Sin
We describe orientifold operation defining O3 plane in the conifold background by deriving it from that of O4 plane in the Type IIA brane construction by T-duality. We find that bo…
Gravitating Self-dual Chern-Simons Solitons
Bok Keun Chung, Jin-Mo Chung, Seongtag Kim +1
Self-dual solitons of Chern-Simons Higgs theory are examined in curved spacetime. We derive duality transformation of the Einstein Chern-Simons Higgs theory within path integral fo…
Induced Lorentz- and CPT-violating Chern-Simons term in QED: Fock-Schwinger proper time method
J. -M. Chung, B. K. Chung
Using the Fock-Schwinger proper time method, we calculate the induced Chern-Simons term arising from the Lorentz- and CPT-violating sector of quantum electrodynamics with a $b_μ\ba…
