摘要：The action density distribution associated with conning ux tube is investigated in SU(2) lattice gauge theory at widely varied lattice spacing. It is argued that the gluon condensate vanishes on the string symmetry axis. We qualitatively conrm the widening of the string with increase of sources separation, however, the broadening seems to be a subleading effect. Instead, it is argued that the string width shrinks linearly with lattice spacing and the action density diverges quadratically keeping the static potential cutoff independent.
