Heavy Flavor Physics Plan to use e- Science The Importance of Heavy Flavor Physics Heavy Flavor Physics Trends An example of e-Science Summary
Heavy Flavor 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.
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
The Unitarity Triangle Graphical expression of unitary condition(s) – 1 triangle has roughly equal-length sides CKM unitarity violation would imply New Physics
Experiments related to CKM parameters Talk by Elisabetta Barberio e + e - B Factories Major experiments ongoing, some ended
Heavy Flavor Physics Trends High Energy Accelerator (up to 14TeV) – From 10.56GeV [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) => Data Processing More Collaborations – From 200 (CLEO) to 2,000 collaborations (CMS) Data Analysis Collaborative => e-Science paradigm will be needed.

The goal of e-Science To study any research anytime and anywhere
The goal of e-Science for HEP Data ProductionData Processing Data Analysis 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. 31 2

Outlook Final dataset from BaBar (~500M B decays) Belle continues operations to get O(1000M decays) Double the dataset at the Tevatron expected High-precision is around the corner. – Final Combined B factories and data set – LHCb – In planning stage: Super B factories in Japan => It is time for e-Science!
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.
