Abstract

We revisit the B+→X(3872)+K+ in the pQCD approach assigning to X(3872) a 23P1 charmonium state. In this theoretical framework all the phenomenological parameters in the wavefunctions and Sudakov factor are a priori fixed by fitting other experimental data; therefore, there hardly are any free parameters in the whole numerical computations. Our results are larger than the upper bound set by the BABAR measurements.
