STRONG EVIDENCE OF THE ρ(1250) FROM A UNITARY MULTICHANNEL REANALYSIS OF ELASTIC SCATTERING DATA WITH CROSSING-SYMMETRY CONSTRAINTS.

Publication Type:Conference

Source(s):Acta Physica Polonica B, Proceedings Supplement. 2022, Vol. 15 Issue 3, p1-7. 7p.

Abstract:We present an analysis of elastic P-wave ππ phase shifts and inelasticities up to 2 GeV in order to identify the corresponding JPC = 1--excited ρ resonances focusing on the ρ(1250) vs. ρ(1450) controversy. In our approach, we employed an improved param...
