4. CKM triangle at Charm-2006
CPV angles only:
η=0.321±0.027
=0.193±0.57
consistent with constraints from measmts of lengths of sides only:
η=0.342±0.022
=0.216±0.036
Simplistic(?) summation: f1+ f2+ f3  182o  ~20o

5. CKM Unitarity Triangle at Charm 2016or
Only experiments in all areas of the
flavor sector will give the answer

6. High energy experiments need low energy inputs.
Likewise g-2 and f-factory measurements

7. Do we understand hadrons?
Swedish academy says
YES!

8. What questions are Charm2006 participants asking?
Are f0(980) & a0(980) qq or qqqq states?
Is there a s? … a k? If so what are they?
Are there glueballs? Where are they?
What are the XYZ particles? …
These questions (& others like them)
betray a fundamental lack of understanding

9. Is this like nuclear physics?
No!
The nuclear physicist doing spectroscopy knows that his nuclei are comprised of protons & neutrons.
We, in contrast, are trying to ascertain the basic nature of the states we deal with.

10. Flavor physics world 2006

11. Flavor physics world 2016

12. BEPC2/BES-III will be the flavor-physics flag bearer
Lots of responsibility
Lots of opportunity
