Matching Heavy Particle Approach to Relativistic Theory

On the simple model of interacting massless and heavy scalar fields it is demonstrated that the technique of heavy baryon chiral perturbation theory reproduces the results of relativistic theory. Explicit calculations are performed for diagrams including two-loops. 03.70.+k 12.39.Fe, Typeset using REVTEX

A Finite Particle Number Approach to Quantum Physics

Bridgman has contended that the "inside of an electron" cannot be given operational meaning. The basic reason for this is taken to be that when relativity is coupled to quantum mechanics the uncertainty principle in energy requires the existence of an indefinitely large number of particulate degrees of freedom corresponding to particles of finite mass when any system is examined at short distan...

Relativistic three-particle scattering equations.

We derive a set of relativistic three-particle scattering equations in the three-particle c.m. frame employing a relativistic three-particle propagator suggested long ago by Ahmadzadeh and Tjon in the c.m. frame of a two-particle subsystem. We make the coordinate transformation of this propagator from the c.m. frame of the two-particle subsystem to the three-particle c.m. frame. We also point o...

Variational Field Theoretic Approach to Relativistic Scattering

Nonperturbative polaron variational methods are applied, within the so-called particle or worldline representation of relativistic field theory, to study scattering in the context of the scalar Wick Cutkosky model. Important features of the variational calculation are that it is a controlled approximation scheme valid for arbitrary coupling strengths, the Green functions have all the cuts and p...

Thermodynamics of Non-Relativistic Scattering Theory

We use thermodynamic Bethe ansatz to study nonrelativistic scattering theory of low energy excitations of 1D Hubbard model, using the S-matrices proposed by Eßler and Korepin. This model can be described by two types of excitation states, holons and spinons, as asymptotic states. In the attractive regime, the spinon is massive while the holon is massless. The situation is reversed with a repuls...
