Study Questions from Tom Browder's Belle II Physics week talk
=============================================================

pg 14 (refer to information from earlier talks):
  - Why is D0-D0bar mixing small?
  - Estimate the ratio of D mixing to B mixing.
  - Estimate the ratio of Bd mixing to Bs mixing.

pg 18:
  - Which of the following types of CP violation have been observed in the B system?
    the D system? the K system?
    - Indirect CP violation in mixing (deltaB=2)?
    - Direct CP violation in decay (deltaB=1)?
    - CP violation in the interference between decay and mixing (deltaB=2)?

pg 23 (referring to the CKM matrix and Wolfenstein parameterization):
  - Which weak interaction quark couplings are complex?
  - Is CP violation possible with two generations of quarks? Explain.
  - Is Vts complex? What about Vcb?
  - Can weak couplings such as Vts and Vtd be measured directly in top quark decays?
    Is this competitive with indirect methods?

pg 24 (referring to the Unitarity Triangle [UT]):
  - Are determinations of UT angles consistent with determinations of the sides?
  - Are angle determinations from loop and tree decays consistent?

pg 25 (referring to the UT):
  - Which modes can be used to determine the interior angles?
  - Draw the lowest order Feynman diagrams that contribute to each mode.
  - Which modes can be used to determine the lengths of the sides?
  - Do you think the theoretical uncertainties are larger for angle or side measurements? Why?

pg 26-27 (referring to the etabar-rhobar plane):
  - How are the y and x axes defined here?
  - What is epsilon(K)? Why is its band so broad?
  - What is Delta(Md)? Delta(Ms)? What is their ratio in terms of CKM parameters?
  - Why is the region for Vub a circular disk?
  - Where are the measurements of B->J/psi KS? Why are there two associated regions?

pg 28 (referring to the time-evolution equations for B0 and B0bar):
  - What happens if you add the two equations?

pg 30:
  - Why does the Upsilon(4S) state vector have a minus sign?

pg 30-31:
  - Why do time-integrated asymmetries vanish at the 4S?
  - Verify the SuperKEKB beta gamma factors.

pg 32 (flavor tagging):
  - What flavor do we have for a l+ or K+ tag?
  - If the b-flavor is not tagged, one cannot observe CP violation or mixing. Why?

pg 37:
  - Explain how the "fast" pion (from B decay) and "slow" pion (from D*+ decay) can be used to tag the b-flavor in B->D*+pi-.
  - Draw appropriate Feynman diagrams.
  - Does the D meson need to be reconstructed?
  - If flavor tagging does not work, can one still measure a CP asymmetry in B0 decays?
    How about B+- decays? Explain.
  - Is a Delta(t) measurement required for CP violation measurements of B->J/psiKS?
    Why or why not? (Hint: think about time-integrated measurements).
