Operator product expansion and analyticity
We discuss the current use of the operator-product expansion in QCD calculations. Treating the OPE as an expansion in inverse powers of an energy-squared variable (with possible exponential terms added), approximating the vacuum expectation value of the operator product by several terms and assuming a bound on the remainder along the euclidean region, we observe how the bound varies with increa...
متن کاملOperator product expansion and confinement
Operator product expansion technique is analyzed in abelian and nonabelian field theoretical models with confinement. Special attention is paid to the regimes where nonzero virtuality of vacuum fields is felt by external currents. It is stressed that despite the physics of confinement is sometimes considered as being caused by " soft " fields, it can exhibit the pronounced " hard " effects in OPE.
متن کاملOperator product expansion at finite temperature
We extend an earlier, configuration space method to find the Wilson coefficients of operators appearing in the short distance expansion of thermal correlation functions of different quark bilinears. Considering all the different correlation functions, there arise, up to dimension four, two new operators , in addition to the two appearing already in the vacuum correlation functions. They would c...
متن کاملOperator product expansion and non-perturbative renormalization
Here A, B, and C are operators; W C (x − y) are c-number functions (Wilson coefficients), singular when |x − y| → 0, that can be computed, for example, in perturbation theory. Dimensional analysis tells us that the leading contribution for y → x is due to the operators C’s in Eq. (1) that have the lowest dimension. Notice that the OPE is an operator relation and therefore, for any matrix elemen...
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...
