2
A similar analysis (KOMADA 2001 ) finds $526$ ${}^{+48}_{-37}$ MeV.
|
3
From the best fit of the Dalitz plot.
|
4
6$\sigma $ effect, no PWA.
|
5
Reanalysis of data from HYAMS 1973 , GRAYER 1974 , SRINIVASAN 1975 , and ROSSELET 1977 using the interfering amplitude method.
|
6
Breit-Wigner fit to S-wave intensity measured in ${{\mathit \pi}}$ ${{\mathit N}}$ $\rightarrow$ ${{\mathit \pi}^{-}}{{\mathit \pi}^{+}}{{\mathit N}}$ on polarized targets. The fit does not include ${{\mathit f}_{{0}}{(980)}}$.
|
7
Uses data from ASTON 1988 , OCHS 1973 , HYAMS 1973 , ARMSTRONG 1991B, GRAYER 1974 , CASON 1983 , ROSSELET 1977 , and BEIER 1972B. Coupled channel analysis with flavor symmetry and all light two-pseudoscalars systems.
|
8
Also observed by ASNER 2000 in ${{\mathit \tau}^{-}}$ $\rightarrow$ ${{\mathit \pi}^{-}}{{\mathit \pi}^{0}}{{\mathit \pi}^{0}}{{\mathit \nu}_{{\tau}}}$ decays.
|
9
Uses ${{\mathit \pi}^{0}}{{\mathit \pi}^{0}}$ data from ANISOVICH 1994 , AMSLER 1994D, and ALDE 1995B, ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ data from OCHS 1973 , GRAYER 1974 and ROSSELET 1977 , and ${{\mathit \eta}}{{\mathit \eta}}$ data from ANISOVICH 1994 .

10
The pole is on Sheet III. Demonstrates explicitly that ${{\mathit f}_{{0}}{(500)}}$ and ${{\mathit f}_{{0}}{(1370)}}$ are two different poles.

11
Analysis of data from OCHS 1973 , ESTABROOKS 1975 , ROSSELET 1977 , and MUKHIN 1980 .
