Abstract

We calculate the next-to-leading order (NLO) QCD corrections to J/ψ associated with W+b production from top quark decay. Our results show that the decay width for process t→J/ψ+W++b+X at the leading order is significantly enhanced by the NLO QCD corrections. This process has the potential to be detected at the LHC. It provides an interesting signature that could be studied at the LHC, and if the J/ψ associated production with W+b from top quark decay is really detected, it will be useful for testing the nonrelativistic QCD factorization formalism.
