The long - range interaction in massless ( λ Φ 4 ) 4 theory
Does massless (λΦ)4 theory exhibit spontaneous symmetry breaking (SSB)? The raw 1loop result implies that it does, but the “RG-improved” result implies the opposite. I argue that the appropriate “low-energy effective theory” is a nonlocal field theory involving an attractive, long-range interaction Φ2(x)Φ2(y)/z4, where z =|x−y |. RG improvement then requires running couplings for both this inte...
متن کامل(nonmeromorphic) operator product expansion and the tensor product theory
In [HL1]–[HL5] and [H1], a theory of tensor products of modules for a vertex operator algebra is being developed. To use this theory, one first has to verify that the vertex operator algebra satisfies certain conditions. We show in the present paper that for any vertex operator algebra containing a vertex operator subalgebra isomorphic to a tensor product algebra of minimal Virasoro vertex oper...
متن کاملSemiclassical Transition in φ 4 Theory ∗
We have shown an example of semiclassical transition in φ4 theory with positive coupling constant. This process can be described by the classical O(4)-invariant solution, considered on a contour in the complex time plane. The transition is technically analogous to the oneinstanton transition in the electroweak model. It is suppressed by the factor exp(−2S0) , where S0 is Lipatov instanton actio...
متن کاملLeading RG logs in φ 4 theory
We find the leading RG logs in φ4 theory for any Feynman diagram with 4 external edges. We obtain the result in two ways. The first way is to calculate the relevant terms in Feynman integrals. The second way is to use the RG invariance based on the Lie algebra of graphs introduced by Connes and Kreimer. The non-RG logs, such as (ln s/t)n, are discussed.
متن کاملNoncommutative Φ 4 Theory at Two Loops
We study perturbative aspects of noncommutative field theories. This work is arranged in two parts. First, we review noncommutative field theories in general and discuss both canonical and path integral quantization methods. In the second part, we consider the particular example of noncommutative Φ 4 theory in four dimensions and work out the corresponding effective action and discuss renormali...
