英文摘要We present a perturbative qcd factorization formula for substructures of an energetic higgs jet, taking the energy profile resulting from the h -> bb bdecay as an example. the formula is written as a convolution of a hard higgs decay kernel with two b-quark jet functions and a soft function that links the colors of the two bquarks. we derive an analytical expression to approximate the energy profile within a boosted higgs jet, which significantly differs from those of ordinary qcd jets. this formalism also extends to boosted wand zbosons in their hadronic decay modes, allowing an easy and efficient discrimination of fat jets produced from different processes.
