Operator Mixing in N = 4 Sym: the Konishi Anomaly Revisited
In the context of the superconformal N = 4 SYM theory the Konishi anomaly can be viewed as the descendant K10 of the Konishi multiplet in the 10 of SU(4), carrying the anomalous dimension of the multiplet. Another descendant O10 with the same quantum numbers, but this time without anomalous dimension, is obtained from the protected half-BPS operator O20′ (the stress-tensor multiplet). Both K10 ...
متن کاملOperator Mixing and Three-point Functions in N = 4 Sym
We study the three-point functions between two BPS and one non-BPS local gauge invariant operators in N = 4 Super Yang-Mills theory. In particular we show, in explicit 1-loop examples, that the operator mixing discussed in arXiv:0810.0499 plays an important role in the computations of the correlators and is necessary to cancel contributions that would violate the constraints following from the ...
متن کاملTri-bimaximal and bimaximal neutrino mixing from discrete sym- metries
— The neutrino oscillation data are well explained by the tri-bimaximal pattern. Recently it has been shown that also the bimaximal pattern could be a very good starting point in order to describe the lepton mixing. In this paper I review both the flavour structures and then I present an explicit example. 1. – The lepton mixing matrix The solar and the atmospheric neutrino anomalies are well ex...
متن کاملContinuity of the Mixing Operator
Mixed distributions are considered as a results of application of a linear operator, which maps mixing measures to mixed measures. The main result is a proof of continuity of this mixing operator. Corollaries for parametric families of distributions (usually considered in literature) are also discussed.
متن کاملNeutrino masses from operator mixing
We show that in theories that reduce, at the Fermi scale, to an extension of the standard model with two doublets, there can be additional dimension five operators giving rise to neutrino masses. In particular there exists a singlet operator which can not generate neutrino masses at tree level but generates them through operator mixing. Under the assumption that only this operator appears at tr...
