The Importance of Heavy Flavor Physics
Heavy Flavor Physics Trends
An example of e-Science
Summary
Let me talk about the important of heavy flavor physics, current heavy flavor physics and future experiment, an example of e-Science and summary.

3. Heavy Flavor Physics?
Heavy flavor physics is an important element in understanding the nature of particle physics.
3 known generations of quark doublets
(u,d),(c,s),(t,b), Electric charge (2/3, -1/3)
Origin of families unknown in SM
Only the charged-current EW interaction can change flavor in the SM.
EW eigenstates are not mass eigenstates.
Only SM connection between generations!
Heavy flavor physics is an important element in understanding the nature of particle physics,
there are three known generations of quark doublets.
Only the charged-current EW interaction can change flavor in the SM.
EW eigenstates are not mass eigenstates. Only there is SM connection between
Generations. This make CKM matrix.

4. CKM matrix elements is fundamental parameters of the Standard Model
CKM matrix elements is fundamental parameters of the Standard Model. They cannot be predicted but can be measured.
F. Di Lodovico, ICHEP 2008

5. Precision measurement of Heavy Flavor Physics
B physics
Can provide confirmation of CKM theory
SM leaves many questions about the flavor sector unanswered:
Origin of generations, masses and mixing, disappearance of antimatter
Core properties of weak interactions
Parameters not predicted within the Standard Model
=> Only measured
Rich phenomenology with few parameters
=>Standard Model measurements: the foundation
=>Deviations: new physics searches
Foundation NP
Let me show the precision measurement of heavy flavor physics.
B physics gives confirmation of CKM theory.
SM leaves many questions about the flavor sector unanswered such as
Origin of generation, masses and mixing, disappearance of antimatter.
However, precision measurement gives core properties of weak interactions.
Such parameters not predicted within the SM..
SM measurements gives the foundation while the deviation gives NP.

6. The Unitarity Triangle
Graphical expression of unitary condition(s)
1 triangle has roughly equal-length sides
CKM unitarity violation would imply New Physics
This shows the unitary triangles.
CKM unitary violation would imply NP.

7. Experiments related to CKM parameters
e+e- B Factories
Major experiments ongoing, some ended
Talk by Elisabetta Barberio

8. This shows the current result of unitary angles by current experiment of hardon and lepton..

9. Heavy Flavor Physics Trends
High Energy Accelerator (up to 14TeV)
From GeV [Y(4S)] (Belle) to 14TeV (CMS)
=> Data Production
High cross section => Lots of data [O(PByte/year)]
From e+e- (Belle) to Hardon Collider (CMS)
=> Data Processing
More Data
From Belle to Super Belle (30X)
More Collaborations
From 200 (CLEO) to 2,000 collaborations (CMS)
Data Analysis Collaborative
=> e-Science paradigm will be needed.

12. The goal of e-Science
To study any research anytime and anywhere

13. The goal of e-Science for HEP
To study High Energy Physics any time, anywhere even if we are not on-site laboratories
Virtual Laboratory enables us to research as if we were on-site.
이제는 고 에너지 물리관련

16. Summary
Heavy flavor physics has an important role for CP violation and decay mechanisms.
Due to higher energy, higher cross section, more data and more collaboration, it is time to use e-Science for heavy flavor physics.
An example of e-Science for CDF experiment has shown.
