Abstract
The very rare Bd0→μ+μ- decay may be the last chance for new physics in the flavor sector at the LHC, before the 13 TeV run in 2015. Partially motivated by the known tension in sinâ¡ 2β/1, enhancement beyond (3-4)×10-10 would likely imply the effect of a fourth generation of quarks. If observed at this level, the 126 GeV boson may not be the actual Higgs boson, while the b→d quadrangle (modulo mt′) would jump out. The 2011-2012 data is likely not sensitive to values below 3×10-10, and the mode should continue to be pursued with the 13 TeV run. © 2013 American Physical Society.
