Scalar QED is taken as an explicit example. More precisely, it is rigorously shown in scalar QED that the naive WI and the improved Ward Identity (‘Master Ward Identity’, MWI) are related to each other by a finite renormalization of the time-ordered product (‘ T -product’) for the derivative fields, and we point out that the MWI has advantages over the naive WI—in particular with regard to the proof of the MWI. We show that the MWI can be fulfilled in all orders of perturbation theory by an appropriate renormalization of the T -product, without conflict with other standard renormalization conditions. Relations with other recent formulations of the MWI are established."],["dc.identifier.doi","10.1007/s00023-021-01048-x"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/85347"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-425"],["dc.relation.eissn","1424-0661"],["dc.relation.issn","1424-0637"],["dc.title","The Master Ward Identity for Scalar QED"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

Many difficulties arise due to the indefinite metric in gauge theoretic approaches, or the increase with the spin of the UV dimension of massive potentials. All these problems can be evaded in one stroke: modify the potentials by suitable terms that leave unchanged the field strengths, but are not polynomial in the momenta. This feature implies a weaker localization property: the potentials are “string-localized”. In this setting, several old issues can be solved directly in the physical Hilbert space of the respective parti-cles: We can control the separation of helicities in the massless limit of higher spin fields and conversely we recover massive potentials with 2s+1degrees of freedom by a smooth deformation of the massless potentials (“fattening”). We construct stress–energy tensors for massless fields of any helicity (thus evading the Weinberg–Witten theorem). We arrive at a simple understanding of the van Dam–Veltman–Zakharov discontinuity concerning, e.g., the distinction between a massless or a very light graviton.
