VES collaboration,D. V. Amelin,E. B. Berdnikov,S. I. Bityukov,G. V. Borisov,R. I. Dzhelyadin,V. A. Dorofeev,A. V. Ekimov,Yu. P. Gouz,A. K. Konoplyannikov,A. N. Karyukhin,I. A. Kachaev,

The production of eta pi - system at low mass by the pi- beam in the Coulomb field of Be nuclei was studied. The cross section of the reaction pi- Be --> eta pi- Be was compared to the experimental data on the decay eta --> pi+ pi- gamma and to the theoretical predictions.

2Investigation of pion-induced formation of the eta pi(-) system in a Coulomb field

DV Amelin,EB Berdnikov,SI Bityukov,GV Borisov,VA Dorofeev,RI Dzhelyadin,AV Ekimov,YP Gouz,IA Kachaev,AN Karyukhin,YA Khokhlov,AK Konoplyannikov,

The pion-induced formation of the low-mass system eta pi(-) in the Coulomb field of a beryllium nucleus has been investigated. The measured cross section for the reaction pi(-)Be --> eta pi(-)Be is compared with a theoretical prediction:based on the observed width of the decay eta --> pi(+)pi(-)gamma.

3Investigation of the Reaction pi(-)+A ->omega pi(-)pi(0)+A

DV Amelin,EB Berdnikov,GV Borisov,VA Dorofeev,RI Dzhelyadin,AV Ekimov,YP Gouz,IA Kachaev,AN Karyukhin,YA Khokhlov,AK Konoplyannikov,SV Kopikov,

A partial-wave analysis of the system omega pi(-)pi(0) has been performed for the reaction pi(-) + A --> pi(+)2 pi(-)2 pi(0) + A* induced by 37-GeV negative pions. A resonance structure with a mass of M approximate to 1.74 GeV and quantum-number values of J(P)M(eta) = 0(-)0(+) has been observed in the invariant-mass distribution for this system. The branching fraction for a(2)(1320) decay into omega pi(-)pi(0) has been determined. A broad structure at M approximate to 1.7 GeV has been revealed in the J(P)M(eta) = 2(+)1(+) partial wave, First observations of the decays pi(2)(1670) --> omega rho(-) and a(4)(2040) --> omega rho(-) are reported.

6Photon Radiation of an Extended Relativistic Object

E. B. Berdnikov,G. G. Nanobashvili,G. P. Pronko

The operator of the electromagnetic interaction of an extended relativistic object is constructed. It is shown that the main difficulty, which arises due to noncommutativity of the coordinates and velocities of the charges in relativistic quantum mechanics, may be overcome by a special ordering of the operators.

11Investigation of the Diffractive Reaction Pi(-)A->Eta Eta Pi(-)A at an Incident P(Pi-) Momentum of 37 Gev/C

DV Amelin,EB Berdnikov,SI Bityukov,GV Borisov,NK Vishnevsky,EV Vlasov,YP Gouz,VA Dorofeev,RI Dzhelyadin,AV Ekimov,AM Zaitsev,YM Ivanyushenkov,

The diffractive production of the eta eta pi(-) system by pi(-) mesons on beryllium nuclei is investigated with a VES detector. The mass spectrum in the range M(eta eta pi)(-)=1.5-2.0 GeV is found to be dominated by the J(PC)=0(+) wave in the a(0)(-)(980)eta channel. This wave has a resonant behavior with parameters M=1840+/-10(stat)+/-10(syst.)MeV and gamma=210+/-30(stat.)+/-30(syst.)MeV. A structure observed in the eta eta mass spectrum may be described in terms of an isobar state with quantum numbers J(P)=0(+) and parameters M approximate to 1460 MeV and (G)amma approximate to 100 MeV.

It is shown that the relative phase between 2(+) and 3(-) is consistent with the two-resonance description. The estimated limits for the pi(0)(1300), pi(2)(1670), omega(1)(1420) and omega(1)(1600) cross sections are also presented.

15Study Of The Decay F()1(1285)-]P(0)(770)Gamma

Dv Amelin,Eb Berdnikov,Si Bityukov,Gv Borisov, Va Odorofeev,Ri Dzhelyadin,Yp Gouz,Ym Ivanyushenkov,Ia Kachaev,An Karyukhin,Ya Khokhlov,Ga Klyuchnikov,

The decay f1(1285) --> rho0(770)gamma was studied at VES spectrometer of IHEP. Clear signal of f1(1285) is seen in the effective mass spectrum of the pi+pi- gamma system in the reaction pi-N --> pi+pi-pi-gammaN at the momentum P(pi-) = 37 GeV/c. The branching fraction of decay f1(1285) --> rho(o)(770)gamma has been found to be BR(f1(1285) --> rho(o)(770)gamma) = (2.8 +/- 0.7(stat) +/- 0.6(syst)).10(-2).The ratio of the helicity amplitudes for rho(o) meson in its rest frame was determined by the analysis of angular distributions:rho00/rho11 = 3.9 +/- 0.9(stat) +/- 1.0(syst).

17Study of Resonance Production in Diffractive Reaction Π−a → Π+π−π−a

The results of the partial wave analysis of the diffractive reaction π−A → π+π−π−A at the momentum 36 GeV/c on the scintillator target are presented. A resonance at m = 1.8 GeV with JPC = 0−+ (π(1800)) is clearly seen in this reaction. The characteristics of π(1800) point to the possible exotic nature of this object.

18Latest Results from the VES Experiment

We present here the results of the VES experiment obtained in 1992–1993: 1) The partial-wave analysis (PWA) has been performed for the reactions$\pi ^ - \mathcal{N} \to \eta \pi ^ - \mathcal{N}$ and$\pi ^ - \mathcal{N} \to \eta \pi ^ - \mathcal{N}$. It has been shown that the intensity of the exotic wave withJPC=1−+ for the η′π- system significantly exceeds that for the ηπ- system. 2) The PWA has been performed for the reactions$\pi ^ - \mathcal{N} \to \pi ^ + \pi ^ - \pi ^ - \mathcal{N}$ and$\pi ^ - \mathcal{N} \to {\rm K}^ + {\rm K}^ - \pi ^ - \mathcal{N}$. The resonance atm=1.8 GeV withJPC=0−+ is clearly seen in both reactions. 3) The radiative decay f1→π(770)γ has been studied. The measured BR(f1(1285)→p0(770)γ)=(3.0±0.7(stat)±0.6(syst))·10-2.

20Study Of The Reaction Pi(-)A-]K+K-Pi(-)A At 37 Gev/C

Eb Berdnikov,Si Bityukov,Gv Borisov,Yp Gouz,Va Dorofeev,Ri Dzhelyadin,Ym Ivanyushenkov,An Karyukhin,Ia Kachaev,Ga Klyuchnikov,Vf Konstantinov,Sv Kopikov,

The reaction pi(-)A --> K(+)K(-)pi(-)A was studied at the momentum of 37 GeV/c on the beryllium target at the wide aperture VES spectrometer. The partial-wave analysis of the K(+)K(-)pi(-) system produced at low \t'\ < 0.08 GeV2 was performed. It is shown that in the wave with J(P) = 0(-) there exists an object with mass 1.79 +/- 0.014 GeV/c(2) and width 0.21 +/- 0.07 GeV/c(2) decaying into kappa K- and f(0)(975)pi(-).
