Test of an Equivalence Theorem at One - Loop
نویسنده
چکیده
We show that the equivalence theorem approximating one-loop gauge sector diagrams by including only Goldstone bosons in the loop gives a remarkably poor approximation to the amplitude for the decay H → γγ and for the process γγ → HH. At one loop, large logarithms can arise that evade power counting arguments.

Myhill-Nerode Fuzzy Congruences Corresponding to a General Fuzzy Automata
Myhill-Nerode Theorem is regarded as a basic theorem in the theories of languages and automata and is used to prove the equivalence between automata and their languages. The significance of this theorem has stimulated researchers to develop that on different automata thus leading to optimizing computational models. In this article, we aim at developing the concept of congruence in general fuzzy...
متن کاملThe exact equivalence of the one-flavour lattice Thirring model with Wilson fermions to a two-colour loop model
Within Euclidean lattice field theory an exact equivalence between the one-flavour 2D Thirring model with Wilson fermions and Wilson parameter r = 1 to a two-colour loop model on the square lattice is established. For noninteracting fermions this model reduces to an exactly solved loop model which is known to be a free fermion model. The two-colour loop model equivalent to the Thirring model ca...

A theorem of Glimm states that representation theory of an NGCR C∗-algebra is always intractable, and the Cuntz algebra ON is a case in point. The equivalence classes of irreducible representations under unitary equivalence cannot be captured with a Borel cross section. Nonetheless, we prove here that wavelet representations correspond to equivalence classes of irreducible representations of ON...
متن کاملFrom Topological to Geometric Equivalence in the Classification of Singularities at Infinity for Quadratic Vector Fields
In the topological classification of phase portraits no distinctions are made between a focus and a node and neither are they made between a strong and a weak focus or between foci of different orders. These distinctions are however important in the production of limit cycles close to the foci in perturbations of the systems. The distinction between the one direction node and the two directions...

Formal analysis remains outside the mainstream of system design practice. Interactive methods and tools are regarded by some to be on the margin of useful research in this area. Although it may seem relatively academic to some, it is vital that this the so-called “theorem proving approach” continue to be as vigorously explored as approaches favoring highly automated reasoning. Design derivation...
