Kihyeon Cho Theory-Experiment To develop the fusion system of theory and experiment Based on this system, we apply to collider experiments in order to probe the standard model (SM) and search for new physics (NP). t tbar asymmetry at Tevatron Higgs mass at Tevatron Polarization of J/ψ at RHIC 12

14. Kihyeon Cho 14 We used dimension-6 qqbar ttbar contact interactions with all the possible Dirac and color structures. We considered the s-, t- and u- channel exchanges of spin-0 and spin-1 particles whose color quantum number is either singlet, octet, triplet or sextet. Our results encode the necessary conditions for the underlying new physics in a compact and an effective way when those new particles are too heavy to be produced at the Tevatron. t tbar Asymmetry at Tevatron Model independent analysis S.-h Nam. et.al, submitted to PRD
