Several of these include an additional $U(1)_X$ gauge group. Chiral fermions' charge assignments under $U(1)_X$ are constrained to cancel local anomalies in the extension and they determine the structure and phenomenology of it. We provide all anomaly-free charge assignments up to a maximum absolute charge of $Q_\text{max}=10$, assuming that the chiral superfield content of the model is that of the MSSM plus up to three Standard Model (SM) singlet superfields. The fermionic components of these SM singlets may play the r\^{o}le of right-handed neutrinos, whereas one of the scalar components may play the r\^{o}le of the flavon, spontaneously breaking $U(1)_X$. Easily scanned lists of the charge assignments are made publicly available on Zenodo. For the case where no restriction is placed upon $Q_\text{max}$, we also provide an analytic parameterisation of the general solution using simple techniques from algebraic geometry. dc.publisher Springer dc.rights Attribution 4.0 International dc.rights.uri https://creativecommons.org/licenses/by/4.0/ dc.subject hep-ph dc.subject hep-ph dc.subject hep-th dc.title A nu supersymmetric anomaly-free atlas dc.type Article dc.publisher.department Department of Applied Mathematics And Theoretical Physics dc.date.updated 2022-01-27T12:05:47Z prism.publicationName JOURNAL OF HIGH ENERGY PHYSICS dc.identifier.doi 10.17863/CAM.80946 dcterms.dateAccepted 2022-01-27 rioxxterms.versionofrecord 10.1007/JHEP02(2022)144 rioxxterms.version AM dc.contributor.orcid Allanach, Benjamin [0000-0003-4635-6830] dc.contributor.orcid Madigan, Maeve [0000-0003-2485-8960] dc.identifier.eissn 1029-8479 rioxxterms.type Journal Article/Review pubs.funder-project-id Science and Technology Facilities Council (ST/P000681/1) pubs.funder-project-id STFC (ST/T000694/1) cam.orpheus.success Wed Mar 23 10:26:27 GMT 2022 - Embargo updated * cam.orpheus.counter 1 cam.depositDate 2022-01-27 pubs.licence-identifier apollo-deposit-licence-2-1 pubs.licence-display-name Apollo Repository Deposit Licence Agreement rioxxterms.freetoread.startdate 2022-02-17
