We consider a massive scalar, neutral, field theory in a five dimensional flat spacetime. Subsequently, one spatial dimension is compactified on a circle, S 1, of radius resulting theory is defined in the manifold, R 3, 1 ⊗ S 1, consists of a states of lowest mass, m 0, and a tower of massive Kaluza-Klein analyticity property of the elastic scattering amplitude is.
Phase shifts for π–π scattering are obtained from a model satisfying Mandelstam analyticity, exact crossing symmetry, and approximate unitarity in the range 2m π ≤ s 1/2 ≤ GeV. The low energy region is dominated by the ρ, ε, and S* poles; the δ 0 0 phase shift is in good agreement with the data obtained by Protopopescu et al.A detailed comparison is made with the available.

scattering amplitudes of hadronic resonances uniquely from analyticity, unitarity and crossing Wednesday, as specifying the basic physical content of the theory. From the unitarity condition S† S = 1, and writing S =1+R,whereR represents the nontrivial scattering in the theory, Heisenberg derives the.
Exploiting unitarity, analyticity and crossing symme-try of the full (unknown) UV complete theory, we will use the known properties of the scattering amplitude of a scalar theory at and away from the forward limit to show that there are an inﬁnite number of such bounds on the pole subtracted scattering.

Using duality in optimization theory we formulate a dual approach to the S-matrix bootstrap that provides rigorous bounds to 2D QFT observables as a consequence of unitarity, crossing symmetry and analyticity of the scattering matrix. We then explain how to optimize such bounds numerically, and prove that they provide the same bounds.
A program for construction of a crossing-symmetric unitary Regge theory of meson-meson scattering is proposed. The construction proceeds through solution of a nonlinear functional equation, ψ = G(ψ), for certain partial-wave scattering functions ψ.
The functional equation is analogous to a conventional dynamical equation, in that the scattering amplitude is generated from input functions. The domain of analyticity of scattering amplitude in s and t variables is extended by imposing unitarity constraints.
A generalized version of Martin’s theorem is derived to prove the existence of such a domain in D-dimensional field theories. Martin, Scattering Theory: Unitarity, Analyticity and Crossing (Springer-Verlag, Berlin.
The properties of the high energy behavior of the scattering amplitude of massive, neutral, and spinless particles in higher dimensional field theories are investigated. The axiomatic formulation of Lehmann, Symanzik, and Zimmermann (LSZ) is adopted. The analyticity properties of the causal, the retarded, and the advanced functions associated with the four point elastic amplitudes are.
In particular, crossing symmetry, gauge invariance and unitarity are satisfied. The extent of violation of analyticity (causality) is used as an expansion parameter. Coherent Compton scattering on light nuclei at MeV is studied in the impulse approximation and is shown to be a sensitive probe of the in-medium properties of the Δ.
analyticity domain as large as possible. Dispersion relations are xed t analyticity properties, in the other variable s,oru as one likes. Another property derived from local eld theory was the existence of the Lehmann ellipse , which states that for xed s, physical, the scattering amplitude is analytic in cos in an 3.if the underlying theory obeys the usual assumptions of Lorentz invariance, analyticity, unitarity and crossing to arbitrarily short distances.
Violations of these bounds can be explained by either the existence of new physics below the naive cut-oﬀ of the the eﬀective theory, or by the breakdown. Certain interactions, such as nuclear forces and the forces of 'high-energy' physics, which arise in the theory of elementary particles, cannot be described successfully by quantum field theory.
Considerable interest has therefore centred on attempts to formulate interactions between elementary particles in terms of the S-Matrix, an operator introduced by Heisenberg which connects the input.
