PARTICLES AS S|MATRIX POLES
On the Connection between Particles and Poles of the S‐Matrix - 1972
Abstract. In axiomatic S-matrix theory it is usually assumed that stable particles give rise to simple poles of the S-matrix for real negative energies while ...

PARTICLES AS S MATRIX POLES: HADRON DEMOCRACY. Geoffrey F. Chew(. LBL, Berkeley. ) Jul, 1985. 10 pages. Part of Proceedings, 2nd International Symposium on on ...
More formally, in the context of QFT, the S-matrix is defined as the unitary matrix connecting sets of asymptotically free particle states (the in-states and ...

S-Matrix Poles for Unstable-Particle Scattering - Oxford Academic
Abstract. We derive an S-matrix representation for scattering when a pole of unstable bound-state, virtual-state or resonance type lies close to the thresh.
On The Pole Structure of the S-Matrix for a Square Well Potential
These poles either correspond to the bounds states or transmission probability depending on whether the energy of the particle is less then or greater then the ...
Correspondence between Unstable Particles and Poles in $S ...
The discussion on the correspondence between unstable particles and poles of the $S$ matrix, started in a previous paper, is continued with particular ...
represent the scattering matrix and the lines represent the momenta of the particles. ... The resonance can be found by finding the S-matrix poles ...
Poles of the S-matrix for a complex potential - ScienceDirect.com
The poles of the S-function in the momentum K-plane for S-wave scattering in a complex well potential are calculated.

Bound states and the S-matrix - Physics
As we discussed above, poles in S ( k ) S(k) S(k) indicate the energy values that correspond to bound states. These are generally on the imaginary- k k k axis, ...
Resonances as poles of the S-matrix
In the present Section we recall the standard theory of the S-matrix and introduce the so-called virtual states, which may appear in the single-particle ...
Phys. Rev. 131, 888 (1963) - Unstable Particles in $S$-Matrix Theory
The consequences of the existence of complex poles in scattering amplitudes, corresponding to resonances or unstable particles, are investigated.
Quantum Field Theory I Chapter 10 10 Scattering Matrix
contains the parameters of the asymptotic particle: The function F2(p) has an isolated pole at the physical mass m, and its residue is the wave function.
We start by considering a quantum particle moving along a line. The maths here will be simple, but the physics is sufficiently interesting to exhibit many of ...
Different manifestations of S-matrix poles - ScienceDirect.com
Provided certain conditions are satisfied by the poles, the residues can also be estimated analytically. Considerations of the low energy behaviour of the S - ...
Observing S-Matrix Pole Flow in Resonance Interplay - arXiv
In theories of quantum scattering, one way to parameterise resonant scattering between particles is by means of poles of the system's ...
On the Prosaic Origin of the Double Poles in the Sine-Gordon S-Matrix
This process is obviously physically possible for classical particles with appropriate initial momenta, provided only that A is sufficiently massive to decay.
S-matrix theory was a proposal for replacing local quantum field theory as the basic principle of elementary particle physics. It avoided the notion of ...
Exotic hadron
Exotic hadrons are subatomic particles composed of quarks and gluons, but which – unlike "well-known" hadrons such as protons, neutrons and mesons – consist of more than three valence quarks.
