Description	Considering analyticity, unitarity and an influence of coupled channels, experimental data on the isovector P-wave of pi pi scattering was analyzed to study rho-like mesons below 1900 MeV. The analysis indicates that in the energy range 1200-1900 MeV, there are possibly four p-like mesons: rho(1250), rho(1450), rho(1600), and rho(1900). The obtained P-wave pi pi-scattering length (a(1)(1) = 33.9 +/- 2.02 vertical bar 10(-3)m(pi+)(-3) vertical bar) matches most to that calculated in the local Nambu-Jona-Lasinio model.

(en) Suvážením analytičnosti,unitarity a vlivem vázaných kanálů byla analyzována data pro vzorektorovou P-vlnu v rozptzlu pionů a studovány ró-podobné mezony do 1900 MeV. Analýza naznaqčuje, že v rozmezí energií 1200-1900 MeV JSOU 4 ró-podobné mezony:rho(1250), rho(1450),rho(1600) a rho(1900). Získaná rozptylová délka pro P-vlnu se nejvíce blíží hodnotě vypočtené v rámci modelu Nambu-Jona-Lasinio. (cs)
