Wednesday, Landau shows similar diagram. According to Tony Hey, the 21st century is for data centric science called e-Science to unify theory, experiment and computing. We apply this concept to collider physics.
The goal is to probe SM and search for new physics. We focus on charm, bottom, top and Higgs.

10. CP violation on Bs-> J/psi @CDF
Analyzed 5.2 fb-1
Including new trigger (TTT) => adds 25% more data
New analysis => cross-check
Optimized data selection => more data than just from multiplying with the increase in luminosity.
Untagged analysis in progress with TTT and comparing with Dimuons

6500 events from dimuon sample now

11. FB Asymmetry at Tevatron
Recently, Tevatron shows t tbar asymmetry. CDF shows forward backward asymmetry is
D0 shows forward backward asymmetry is

12. FB asymmetry @ Tevatron
Model independent analysis
We used dimension-6 four quark operators 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.
The region in (C1,C2) plane that is consistent with the Tevatron data at the one sigma level.
For t tbar asymmetry of Tevatron, we use model independent analysis. This shows ttbar invariant mass vs. cross section.

e-Science 기반의 하이 에너지 물리 즉 e-Hep은
“언제나, 어디서나, 가속기 연구소와 같은 연구 환경 제공”을 목표로 하고 있습니다.
구체적인 목표로,
실제 CERN이나 Fermi 연구소와 같은 외국의 거대 가속기 연구소의
일부분을 우리나라에 확장함으로써
가상 입자 가속기 연구소를 구축하려고 노력하고 있습니다.
앞으로 네가지의 가장 연구소의 시설을 규모와 중요도의 순서대로 제시하겠습니다. 2 1 3 1
