Revisiting the pion Regge trajectories
We propose a model-independent ansatz M=βx(x+c0)ν+c1 (x=l,nr) and then use it to fit the orbital and radial pion Regge trajectories without the preset values. It is shown that nonzero c1 is reasonable and acceptable. Nonzero c1 gives an explanation for the nonlinearity of the pion Regge trajectories...
