We discuss the action of SL(2, Z) on local operators in D = 4, N = 4 SYM theory in the superconformal phase. The modular property of the operator’s scaling dimension determines whether the operator transforms as a singlet, or covariantly, as part of a finite or infinite dimensional multiplet under the SL(2, Z) action. As an example, we argue that operators in the Konishi multiplet transform as ...

This chapter reports on some of the work carried out in COST-231 with relation to second generation personal communication systems, and specifically GSM and DECT. The performance of basic versions of such systems is relatively well known, and the focus of the work was therefore on advanced features and possible limitations. These topics are of importance not only in relation to the full exploit...

N = 1 SQCD with SU(Nc) colors and NF flavors of light quarks is considered within the dynamical scenario which assumes that quarks can be in two different phases only. These are : a) either the HQ (heavy quark) phase where they are confined, b) or they are higgsed, at the appropriate values of parameters of the Lagrangian. The mass spectra of this (direct) theory and its Seiberg’s dual are obta...

With the renewed interest in the field of second language learning for the knowledge of collocating words, research findings in favour of holistic processing of formulaic language could support the idea that these language units facilitate efficient language processing. This study investigated the difference between processing of a first language (L1) and a second language (L2) of congruent col...
