Strategy / Disclaimer

• Phenomena Pertinent to BSM • Physics (vs Expt’l detail — not always most up-to-date)

[No “B Chemistry” (goto CKM meeting (Tim Gershon), if desired)

• Short-term impact This Decade 2010−2019

• “Traditional” on BSM topics

• Cannot cite all TH work, but unabashedly promote own pheno work

and not too tricky ...

vs 2000−2009
