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

Kihyeon Cho K. Tollefson t tbar Asymmetry at Tevatron

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

Kihyeon Cho Results ⇒ Great success of Experiment-Computing-Theory in collider physics

Kihyeon Cho Summary The e-Science environment of data production, processing and analysis enables us to study collider physics any time anywhere. We showed the e-Science paradigm of experiment, theory and computing in collider physics as new research paradigm in computational physics. 22
