We demonstrate that in supersymmetry (SUSY) with relatively light top
superpartners, h -> bb can be a very promising channel to discover the SM-like
Higgs resonance at the Large Hadron Collider (LHC), although in general
contexts it is thought to be challenging because of its huge QCD background. In
this scenario, the SM-like Higgs boson is mainly produced via cascade decays
initiated by pair-produced stop or sbottom squarks. The good sensitivity to h
-> bb owes a great deal to the application of multiple (>= 4) b-jet tagging in
removing the QCD background, and color-flow variables for reconstructing the
Higgs resonance. We show in two benchmark points that a SM-like Higgs resonance
can be discovered at the 14 TeV LHC (with a signal-to-background ratio as high
as 0.35), with ~< 40/fb of data. Potentially, this strategy can be also applied
to non-SUSY theories with cascade decays of top partners for the SM-like Higgs
search, such as little Higgs, composite Higgs, and Randall-Sundrum models.Comment: 6 pages, 8 figures, 2 tables; final version for Phys. Rev.
