Dispersive calculation of complex Regge trajectories for the lightest $f_2$ resonances

J. A. Carrasco, J. Nebreda, J. R. Pelaez +1

We apply a recently developed dispersive formalism to calculate the Regge trajectories of the $f_2(1270)$ and $f_2^{\prime }(1525)$ mesons. Trajectories are calculated, not fitted to a fami…
