On Infrared Universality in Massive Theories. Another Example
نویسنده
چکیده
The infrared behaviour of the φ 3-theory is discussed stressing analogies with the Witten-Seiberg story about N = 2 QCD. Though the microscopic theory is apparently not integrable, the effective theory is shown to be integrable at classical level, and a general solution of it in terms of hypergeometric functions is obtained. An effective theory for the multiparticle soft scattering is sketched.

Colocalization of Lichen Planus and Vitiligo: Challenging the Universality of Current Theories
Vitiligo and Lichen Planus, two common dermatologic disorders, are expected to coexist. This leads to diverse theories regarding their immunopathogenesis linkage. In this case, we report a twenty-year-old man suffering from simultaneous lichen planus and vitiligo which were both generalized at the time of observation and also concomitant throughout their entire course of progression. Lichen Pla...
متن کاملUniversality in Two Dimensional Gauge Theory
We discuss two dimensional Yang – Mills theories with massless fermions in arbitrary representations of a gauge group G. It is shown that the physics (spectrum and interactions) of the massive states in such models is independent of the detailed structure of the model, and only depends on the gauge group G and an integer k measuring the total anomaly. The massless physics, which does depend on ...
متن کاملSolitons and Helices: The Search for a Math-Physics Bridge
We present evidence for an undiscovered link between N=2 supersymmetric quantum field theories and the mathematical theory of helices of coherent sheaves. We give a thorough review for nonspecialists of both the mathematics and physics involved, and invite the reader to take up the search for this elusive connection. Last year, Kontsevich noticed a similarity between the work of Cecotti and Vaf...
متن کاملQuantum Diffusion Process with a Complex Weight on Three Dimensional Lattice
A rigorous definition of a path integral for a spinning particle in three dimensions is given on a regular cubic lattice. The critical diffusion constant and the associated critical exponents in each spin are calculated. Continuum field theories such as Klein-Gordon, Dirac and massive Chern-Simons theories are constructed near these critical points. The universality of obtained results is argue...
متن کاملFactorization in One-Loop Gauge Theory
Factorization properties of one-loop gauge theory amplitudes have been used as checks on explicitly computed amplitudes and in the construction of ansätze for higher-point ones. In massless theories, such as QCD at high energies, infrared divergences complicate factorization. Here we prove that factorization in such theories is described by a set of universal functions. In particular, a proof o...
