Dalitz plots and lineshape of $a_1(1260)$ from a relativistic three-body unitary approach
We formulate the final-state interaction of the a1(1260) resonance decay in a manifestly three-body unitary parametrization and fit it to the a1(1260) line shape measured by the ALEPH experiment. Dalitz plots calculated from this fit are presented. The work demonstrates the feasibility to numericall...
