摘要：We discuss the long distance behaviour of the ux tube associated to baryon vertices and argue
that, if the gauge system admits stable k-strings, the conformal eld theory describing this string
in the IR has conformal anomaly c
d

sk
s , where sk is the k-string tension and s that of
the fundamental representation. We check this result in a 3D
4 gauge model at nite temperature,
where a string effect directly related to c can be clearly identied.
