Bv. Geshkenbein, GLUON AND 4-QUARK CONDENSATES FROM ANALYSIS OF THE FAMILIES OF VECTOR-MESONS CONSISTING OF LIGHT QUARKS, Physics of atomic nuclei, 59(2), 1996, pp. 289-296
The magnitude of gluon condensate is found from analysis of the famili
es of vector mesons consisting of light quarks (the families of rho, o
mega, and phi mesons). The result is [0/(alpha(s)/pi)G(2)/0] = 0.061 /- 0.019 GeV4, which agrees with the magnitude obtained from analysis
of the families of J/psi and gamma [Geshkenbein, B.V. Yad. Fit., 1990,
vol. 51, p. 1121; Geshkenbein, B.V. and Morgunov, V.L., Yad. Fiz., 19
95, vol. 58, p. 1873]. The magnitude of the four-quark condensate is c
alculated. The electronic widths of rho(770), rho(1450), omega(1420),
and phi(1680) mesons are refined and the phi(2000) mass is calculated.
