In this review, three subjects are discussed: a phenomenological application of lattice predictions to K 0 – ¯ K 0 mixing in Super Symmetry; a discussion of the non-perturbative renormalization methods for four-fermion operators and a new approach to extract weak matrix elements in effective theories denoted as OPE without OPE (operator product expansion without operator product expansion).

With the growing importance of cloud computing, database encryption has become a critical technology to protect data against honest-but-curious attackers. Our goal is to encrypt the data in such a way that it remains protected against powerful attackers and at the same time achieve good performance by processing queries in the cloud without decrypting the data. Order-Preserving Encryption (OPE)...

We perform the QCD testing of the Quasilocal Quark Model (QQM) based on Operator Product Expansion (OPE). The quark current correlators calculated in framework of the model, are compared to their OPE in QCD at intermediate energies. The QQM provides a reasonable resolution for mass spectrum of parity doublers in scalar and vector meson channels.

We consider the operator product expansion (OPE) of correlation functions in supersymmetric $O(N)$ non-linear sigma model at sub-leading order large $N$ limit to study cancellation between ambiguities coming from infrared renormalons and those various operators OPE. As has been discussed context Yang-Mills theory four dimensions, supersymmetry presents a challenge this cancellation. In bid solv...

All the three point couplings involving tachyons and/or discrete states are obtained in c = 1 two-dimensional (2-D) quantum gravity by means of the operator product expansion (OPE). Cocycle factors are found to be necessary in order to maintain the analytic structure of the OPE, and are constructed explicitly both for discrete states and for tachyons. The effective action involving tachyons and...

In this work we push the matching between the QCD operator product expansion (OPE) and resonance chiral theory (RχT) to order αs. To this end we compute two– and three–point QCD Green functions (GFs) in both theories and compare the results. GFs which are order parameters of chiral symmetry breaking make this matching more transparent and thus we concentrate on those. On the OPE side one needs ...
