Abstract :
A functional renormalisation group is applied to the few-nucleon problem. We have considered the average effective action with exact S U ( 4 ) symmetry and derived the flow equations which have been used to calculate the deuteron–deuteron scattering lengths in the singlet and quintet spin–isospin channels.
