Regge Behaviour from an Environmentally Friendly Renormalization Group 1
نویسندگان
چکیده
The asymptotic behaviour of cubic field theories is investigated in the Regge limit using the techniques of environmentally friendly renormalization, environmentally friendly in the present context meaning asymmetric in its momentum dependence. In particular we consider the crossover between large and small energies at fixed momentum transfer for a model scalar theory of the type φ 2 ψ. The asymptotic forms of the crossover scaling functions are exhibited for all two particle scattering processes in this channel to one loop in a renormalization group improved perturbation theory.

متن کاملEnvironmentally Friendly Renormalization Group and Phase Transitions
We discuss an environmentally friendly renormalization group approach to analyze phase transitions. We intend to apply this method to the Electroweak Phase Transition. This work is in progress. We present some previously obtained results concerning a λφ 4 theory, where the main features of this algorithm are introduced.
متن کاملQuantum Field Theory in the Limit x ≪ 1 1
The asymptotic high momentum behaviour of quantum field theories with cubic interactions is investigated using renormalization group techniques in the asymmetric limit x ≪ 1. Particular emphasis is paid to theories with interactions involving more than one field where it is found that a matrix renormalization is necessary. Asymptotic scaling forms, in agreement with Regge theory, are derived fo...
متن کامل" Environmentally Friendly " Way!
We discuss how to implement an " environmentally friendly " renormalization in the context of finite temperature field theory. Environmentally friendly renormalization provides a method for interpolating between the different effective field theories which characterize different asymptotic regimes. We give explicit two loop Padé resummed results for λφ 4 theory for T > T c. We examine the impli...
متن کاملEffective critical exponents for dimensional crossover and quantum systems from an environmentally friendly renormalization group.
Series for the Wilson functions of an " environmentally friendly " renor-malization group are computed to two loops, for an O(N) vector model, in terms of the " floating coupling " , and resummed by the Padé method to yield crossover exponents for finite size and quantum systems. The resulting effective exponents obey all scaling laws, including hyperscaling in terms of an effective dimensional...
