Erratum: Signatures of anomalousVVHinteractions at a linear collider [Phys. Rev. D73, 035001 (2006)]

Abstract

There was a transcription error in Section II.A in the sentence spanning lines 10 -12 : The sentence ''It is easy to see that a nonvanishing value for either =b V or <b V destroys the Hermiticity of the effective theory.'' should read ''It is easy to see that a nonvanishing value for either =b V or =b V destroys the Hermiticity of the effective theory.'' The rest of the analysis and discussion remain unchanged. We wish to thank the Editorial Board Members of the CPNSH report, S. Kraml, M. Krawczyk , H. Haber and G. Granier who spotted this lapse.

Role of polarization in probing anomalous gauge interactions of the Higgs boson

“…In fact, the observables listed here are the same ones as considered in Ref. [34], but here we use them for a specific polarisation of initial beams and final state τ 's. Needless to say, we concentrate on the cases where use of polarisation affords a distinct gain in sensitivity.…”

“…[31] is one of the pioneering studies and contains a very extensive analysis, using the optimal observable technique [36], to probe ZZH and γZH couplings, whereas Refs. [32][33][34] use asymmetries constructed using differences in the kinematical distributions of the decay products.…”

“…[34], an exhaustive set of asymmetries, which could probe each of the ZZH anomalous coupling independent of the others, were constructed. Defining kinematical observables which are either odd or even under the different discrete symmetry transformations, the said asymmetries are the expectation values of the sign of these observables.…”

“…The anomalous ZZH vertex, in the context of higher dimensional operators has been studied in Refs. [26][27][28][29][30][31][32][33][34][35] for a Linear Collider (LC). Ref.…”

“…[34] for the case of unpolarised beams had revealed that various asymmetries probing the ZZH anomalous couplings were in fact proportional to (l 2 f −r 2 f ) where l f (r f ) denote the coupling of a Z boson to a left-(right-)handed fermion. Use of polarised beams or detection of a τ with a specific polarisation in the final state can then avoid the cancellation between these two terms and may lead to an enhancement in sensitivity.…”
