General Formulae of Invariant Functions of the Generalized Reaction Γn → Γn in the Effective Lagrangians Method

چکیده
The crossed channels of generalized reaction γN → γN have been considered. The transformation coefficients from the independent helicity amplitudes to the invariant functions are calculated. The explicit expressions for invariant functions have been obtained with the subject to the contribution of Born diagrams in s-, u-, and t-channel and six resonances in sand u-channel. It has been shown that the obtained invariant functions meet the requirements of crossing-symmetry.

Taking the Pirahã Seriously
We propose first order formal theories Γn, with n ≥ 1, and Γ = ⋃ n≥1 Γn, which can be roughly described as follows: each one of these theories axiomatizes a bounded universe, with a greatest element, modelled on Sergeyev’s so-called grossone; each such theory is consistent if predicative arithmetic I∆0 + Ω1 is; inside each such theory one can represent (in a weak, precisely specified, sense) th...
متن کاملCoupled Channel Study of K + Λ Photoproduction
A coupled channel model with γN , KY and πN channels has been used to analyze the recent data of γp → K + Λ. The non-resonant interactions within the subspace KY ⊕ πN are derived from effective Lagrangians using a unitary transformation method. The direct photoproduction reaction is obtained from a chiral constituent quark model with SU (6) ⊗ O(3) breaking. Missing baryon resonances issues are ...
متن کاملAsymptotic Behavior of Partition Functions with Graph Laplacian
We introduce the matrix sums that represent a discrete analog of the matrix integrals of random matrix theory. The summation runs over the set Γn of all possible n-vertex graphs γn weighted by exp{−β Tr∆n}, β > 0, where ∆n = ∆(γn) is the analog of the Laplace operator determined on γn. Corresponding probability measure on Γn reproduces the well-known Erdős-Rényi ensemble of random graphs. Here ...
متن کاملun 1 99 6 Meson - exchange Model for πN Scattering and γN → πN Reaction
An effective Hamiltonian consisting of bare ∆ ↔ πN , γN vertex interactions and energy-independent meson-exchange πN ↔ πN, γN transition operators is derived by applying a unitary transformation to a model Lagrangian with and coupling constants for ρ and ∆, the model can give a good description of πN scattering phase shifts up to the ∆ excitation energy region. It is shown that the best reprodu...
متن کاملQuantitative estimates in approximation by Bernstein-Durrmeyer-Choquet operators with respect to monotone and submodular set functions
For the qualitative results of pointwise and uniform approximation obtained in [10], we present general quantitative estimates in terms of the modulus of continuity and in terms of a K-functional, for the generalized multivariate Bernstein-Durrmeyer operator Mn,Γn,x , written in terms of the Choquet integral with respect to a family of monotone and submodular set functions, Γn,x, on the standar...
