Quasielastic rho0 electroproduction on the proton at intermediate energy: Role of scalar and pseudoscalar meson exchange

Autor: Obukhovsky, I. T., Faessler, Amand, Fedorov, D. K., Gutsche, Thomas, Lyubovitskij, Valery E., Neudatchin, V. G., Sviridova, L. L.

Publikováno v: Phys.Rev.D81:013007,2010

We present a detailed analysis of rho(0) electroproduction at intermediate energy for quasi-elastic knockout kinematics. The approach is based on an effective Lagrangian which generates exchanges of scalar, pseudoscalar, axial-vector and tensor meson

Quasi-elastic knockout of pions and kaons from nucleons by high-energy electrons and quark microscopy of 'soft' meson degrees of freedom in the nucleon

Autor: Neudatchin, V. G., Obukhovsky, I. T., Sviridova, L. L., Yudin, N. P.

Publikováno v: Nucl.Phys. A739 (2004) 124-150

Electro-production of pions and kaons at the kinematics of quasi-elastic knockout (which is well known in the physics of atomic nucleus and corresponds to the $t$-pole diagram) is proposed for obtaining their momentum distribution (MD) in various cha

Microscopics of meson degrees of freedom in nucleons and mesons in nuclei - what can be seen in the process of quasielastic knockout of mesons by high-energy electrons

Autor: Neudatchin, V. G., Obukhovsky, I. T., Sviridova, L. L., Yudin, N. P.

Publikováno v: Phys.Atom.Nucl. 67 (2004) 470-481; Yad.Fiz. 67 (2004) 490-500

Developed earlier concept of quasielastic knock out of pions from nucleons by high-energy electrons is propounded as a tool for checking microscopical model ($^3P_0$ - fluctuation) for decay of N to different channels $\pi+B$ and Preparata model of n

Report

Pionic Degrees of Freedom in Atomic Nuclei and Quasielastic Knockout of Pions by High-Energy Electrons

Autor: Neudatchin, V. G., Yudin, N. P., Sviridova, L. L., Yudin, S. N.

Publikováno v: Eur.Phys.J.A24:217-222,2005

The nonlinear model of pionic condensate in nuclei by G. Preparata can be efficiently verified by investigation of the quasielastic knockout process of pions out of nuclei by high energy electrons. First, a momentum distribution (MD) of the collectiv
