• 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 ...
