We compute the one-loop bubble diagram part of the self-energy of the spin 0 member of the tower by summing up all higher-spin loop contributions. We find that the result contains an exponentially UV divergent part and we discuss how it could be cancelled by a tadpole contribution depending on yet to be determined quartic interaction vertex. We also compute the tree-level four-scalar scattering amplitude due to all higher-spin exchanges and discuss its inconsistency with the BCFW constructibility condition. We comment on possible relation to similar computations in AdS background in connection with AdS/CFT.", "revisions": [ { "version": "v1", "updated": "2016-03-20T21:32:17.000Z" } ], "analyses": { "keywords": [ "flat space", "higher-spin theory", "quantum corrections", "one-loop bubble diagram part", "exponentially uv divergent part" ], "note": { "typesetting": "TeX", "pages": 33, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2016arXiv160306273P", "inspire": 1430933 } } }
