2 Heavy Flavor Physics Plan to use e-Science The Importance of Heavy Flavor PhysicsHeavy Flavor Physics TrendsAn example of e-ScienceSummaryLet 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 SMOnly 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 betweenGenerations. 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 physicsCan provide confirmation of CKM theorySM leaves many questions about the flavor sector unanswered:Origin of generations, masses and mixing, disappearance of antimatterCore properties of weak interactionsParameters not predicted within the Standard Model=> Only measuredRich phenomenology with few parameters=>Standard Model measurements: the foundation=>Deviations: new physics searchesFoundationNPLet 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 asOrigin 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 sidesCKM unitarity violation would imply New PhysicsThis shows the unitary triangles.CKM unitary violation would imply NP.
7 Experiments related to CKM parameters e+e- B FactoriesMajor experiments ongoing, some endedTalk 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 ProductionHigh cross section => Lots of data [O(PByte/year)]From e+e- (Belle) to Hardon Collider (CMS)=> Data ProcessingMore DataFrom Belle to Super Belle (30X)More CollaborationsFrom 200 (CLEO) to 2,000 collaborations (CMS)Data Analysis Collaborative=> e-Science paradigm will be needed.

12 The goal of e-ScienceTo 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 laboratoriesVirtual Laboratory enables us to research as if we were on-site.이제는 고 에너지 물리관련KISTI e-Science 사업단의 활동과 성과에 대해서 설명..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 연구소의일부분을 우리나라에 확장함으로써가상 입자 가속기 연구소를 구축하려고 노력하고 있습니다.앞으로 네가지의 가장 연구소의 시설을 규모와 중요도의 순서대로 제시하겠습니다.231Data AnalysisData ProductionData Processing

16 SummaryHeavy 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.
