’t HOOFT ANOMALY MATCHING FOR DISCRETE SYMMETRIES
We show how to extend the ’t Hooft anomaly matching conditions to discrete symmetries. We check these discrete anomaly matching conditions on several proposed low-energy spectra of certain strongly interacting gauge theories. The excluded examples include the proposed chirally symmetric vacuum of pure N = 1 supersymmetric Yang-Mills theories, certain nonsupersymmetric confining theories and som...
متن کاملHooft Anomaly Matching for QCD
I present a set of theories which display non-trivial ‘t Hooft anomaly matching for QCD with F flavors. The matching theories are non-Abelian gauge theories with “dual” quarks and baryons, rather than the purely confining theories of baryons that ‘t Hooft originally searched for. The matching gauge groups are required to have an F ± 6 dimensional representation. Such a correspondence is reminis...
متن کاملDiscrete R-Contiguous bit Matching mechanism appropriateness for anomaly detection in Wireless Sensor Networks
Resource exhaustion is one of the main challenges for the security of Wireless Sensor Networks (WSNs). The challenge can be addressed by using algorithms that are light weighted. In this paper use of light-weighted RContiguous Bit matching for attack detection in WSNs has been evaluated. Use of R-Contiguous bit matching in Negative Selection Algorithm (NSA) has improved the performance of anoma...
متن کاملSequence Matching and Learning in Anomaly
Two problems of importance in computer security are to 1) detect the presence of an intruder masquerading as the valid user and 2) detect the perpetration of abusive actions on the part of an otherwise innocuous user. We have developed an approach to these problems that examines sequences of user actions (UNIX commands) to classify behavior as normal or anomalous. In this paper we explore the m...
متن کاملAnomaly Matching Conditions in Supersymmetric Gauge Theories
Sufficient conditions are proven for ’t Hooft’s consistency conditions to hold at points in the moduli space of supersymmetric gauge theories. Known results for anomaly matching in supersymmetric QCD are rederived as a sample application of the results. The results can be used to show that the anomaly matching conditions hold for s-confining theories. Typeset using REVTEX 1 One important constr...
