Research Interests of Kim Choong Sun
(±èÃæ¼±, C. S. Kim)Theoretical Particle Physics My research activities have been broadly focused on phenomenological aspects of theoretical particle physics in (1) collider physics [eg. search for top and Higgs, gauge boson production and neutrino counting, determination of parton distributions, heavy quarkonium production, and jets and minimumbias physics (minijets), etc.], and in (2) weak flavordynamics [eg. CPviolation, heavy meson physics, particleantiparticle mixing, CKMmatrix and quark and neutrino masses, etc.]. I have also extensively investigated (3) the phenomenology of the Beyond the Standard Model [eg. charged Higgs, lightest SUSY particle, superstring phenomenology, new Higgsless flavor gauge theory, Extra Dimensions, etc.]. In the course of this research, I have also familiarized myself with (4) the experimental side of particle physics [detectors, accelerators, etc.] as well as (5) Monte Carlo computer simulations, and computation of Feynman diagrams [including spinor technic, ndimensional and numerical methods], and so on. At present I have been involved in the ongoing work of (1) CPviolations in K, Bmeson systems and in Universe. My immediate research plans are; (2) Bmeson rare decays such as B > K*(> K+pi)+l+l, and (3) the combined analyses of BB mixing and B > l+l decays modelindependently, and (4) the possible extra dimensional signal at e+p colliders. My longterm research interests are; (1) quantative tests of QCD at the intermediate [few GeV] domain where both perturbative and nonperturbative aspects of the theory are manifest, (2) detailed and modelindependent study of weak decays such as hadronic weak currents, mixing and CPviolation, rare decays, etc., (3) search for the new particles by selecting the few events of interests through imposing judicious cuts, (4) exploring regions between high energy particle physics and cosmology, and (5) investigation on microscopic properties of Gravity through extra dimensional signals and/or violations of Lorentz (and CTP) invariances.
