Regge-eikonal Approach and Its Off-shell Extention versus Experimental Data

چکیده
V. A. PETROV AND A. V. PROKUDIN Institute For High Energy Physics, 142284 Protvino , Russia E-mail: [email protected] [email protected] We develop an off-shell extention of the Regge-eikonal approach which automatically takes into account off-shell unitarity. We argue that exclusive vector-meson production cross-sections measured at HERA can be fairly described with classical universal Regge trajectories. No extra “hard” trajectories of high intercept are needed for that.

Fragmentation and Energy Conservation - Ci in the Eikonal - Regge Model
We have studied the effect of fragmentation and energy conservation in the Eikonal-Regge model. A generalized eikonal representation involving multiimpact-parameters is given for the elastic and inelastic amplitudes when fragmentation takes place. The generalized eikonal function depends on more than one impact parameter which describes a many-body potential. In the strong absorption model and ...
متن کاملIntranuclear Cascade versus Eikonal Approximation Typeset Using Revt E X 2
The problem of nucleon propagation through the nuclear medium in quasielastic A(e, e ′ p) reactions is discussed in the kinematic range 1 ≤ Q 2 ≤ 7 (GeV/c) 2. Experimental data are available from SLAC, BATES and, recently, also from TJNAF. The coefficient of nuclear transparency is calculated for each Q 2 in the framework of the intranuclear cascade model (INC) and of the eikonal approximation ...

Exclusive Double Diffractive Events (EDDE) are analysed as the source of information about the central system. Experimental possibilities for exotic particles searches are considered. From the reggeized tensor current picture some azimuthal angle dependences were obtained to fit the data from WA102 experiment and to make predictions for LHC collider.

A mathematical model is presented in the present study to control the light propagation in an inhomogeneous media. The method is based on the identification of the optimal materials distribution in the media such that the trajectories of light rays follow the desired path. The problem is formulated as a distributed parameter identification problem and it is solved by a numerical met...
متن کاملOff-shell Gauge Fields from BRST Quantization
We propose a construction for nonlinear off-shell gauge field theories based on a constrained system quantized in the sense of deformation quantization. The key idea is to consider the star-product BFV–BRST master equation as an equation of motion. The construction is formulated in terms of the BRST extention of the unfolded formalism that can also be understood as an appropriate generalization...
