They feature a pair of vielbeins corresponding to the same spacetime metric, and hence enjoy double local Lorentz symmetries. In a manifestly covariant manner --with regard to O(D,D) T-duality, diffeomorphism, B-field gauge symmetry and the pair of local Lorentz symmetries-- we incorporate R-R potentials into double field theory. We take them as a single object which is in a bi-fundamental spinorial representation of the double Lorentz groups. We identify cohomological structure relevant to the field strength. A priori, the R-R sector as well as all the fermions are O(D,D) singlet. Yet, gauge fixing the two vielbeins equal to each other modifies the O(D,D) transformation rule to call for a compensating local Lorentz rotation, such that the R-R potential may turn into an O(D,D) spinor and T-duality can flip the chirality exchanging type IIA and IIB supergravities.", "revisions": [ { "version": "v2", "updated": "2012-08-22T23:27:43.000Z" } ], "analyses": { "subjects": [ "04.65.+e", "04.60.Cf" ], "keywords": [ "ramond-ramond cohomology", "double field theory", "enjoy double local lorentz symmetries", "b-field gauge symmetry", "incorporate r-r potentials" ], "tags": [ "journal article" ], "publication": { "publisher": "Springer", "journal": "Journal of High Energy Physics", "year": 2012, "month": "Sep", "volume": 2012, "pages": 79 }, "note": { "typesetting": "TeX", "pages": 37, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1118459, "adsabs": "2012JHEP...09..079J" } } }
