Smooth crossover transition from the Delta-string to the Y-string three-quark potential
Апстракт
We comment on the assertion made by Caselle et al. [M. Caselle, G. Delfino, P. Grinza, O. Jahn, and N. Magnoli, J. Stat. Mech. (2006) P008.] that the confining (string) potential for three quarks makes a smooth crossover transition from the Delta-string to the Y-string configuration at interquark distances of around 0.8 fm. We study the functional dependence of the three-quark confining potentials due to a Y-string, and the Delta string and show that they have different symmetries, which lead to different constants of the motion (i.e. they belong to different universality classes in the parlance of the theory of phase transitions). This means that there is no smooth crossover between the two, when their string tensions are identical, except at the vanishing hyper-radius. We also comment on a certain two-body potential approximation to the Y-string potential.
