Abstract: The Bs→K transition form factor was studied by means of light cone QCD sum rule in the whole kinematically accessible range. We chose a new correlation to eliminate the effect from the twist-3 function, thus, we can extract the CKM matrix element |Vub| precisely.

Key words: light cone QCD sum rule, form factor, CKM matrix element
