In this work we apply recent general results on the spectrum of coset space models and on supergroup WZNW models to study the conformal sigma model with target space S$^{3|2}$. We construct its vertex operators and provide explicit formulas for their anomalous dimensions, at least to leading order in the sigma model coupling. The results are used to revisit a non-perturbative duality between the supersphere and the OSP(4|2) Gross-Neveu model that was conjectured by Candu and Saleur. With the help of powerful all-loop results for $ \frac{1}{2}\mathrm{B}\mathrm{P}\mathrm{S} $ operators in the Gross-Neveu model we are able to recover the entire zero mode spectrum of the sigma model at a certain finite value of the Gross-Neveu coupling. In addition, we argue that the sigma model constraints and equations of motion are implemented correctly in the dual Gross-Neveu description. On the other hand, high(er) gradient operators of the sigma model are not all accounted for. It is possible that this discrepancy is related to an instability from high gradient operators that has previously been observed in the context of Anderson localization. 000191862 536__ $$0G:(DE-HGF)POF2-514$$a514 - Theoretical Particle Physics (POF2-514)$$cPOF2-514$$fPOF II$$x0 000191862 536__ $$0G:(EU-Grant)317089$$aGATIS - Gauge Theory as an Integrable System (317089)$$c317089$$fFP7-PEOPLE-2012-ITN$$x1 000191862 588__ $$aDataset connected to INSPIRE 000191862 650_7 $$2INSPIRE$$asigma model: conformal 000191862 650_7 $$2INSPIRE$$azero mode: spectrum 000191862 650_7 $$2INSPIRE$$aoperator: vertex 000191862 650_7 $$2INSPIRE$$agradient: high 000191862 650_7 $$2INSPIRE$$aoperator: BPS 000191862 650_7 $$2INSPIRE$$afield theory: conformal 000191862 650_7 $$2INSPIRE$$aGross-Neveu model 000191862 650_7 $$2INSPIRE$$acoset space 000191862 650_7 $$2INSPIRE$$aduality 000191862 650_7 $$2INSPIRE$$aWess-Zumino-Witten model 000191862 650_7 $$2INSPIRE$$aAdS/CFT correspondence 000191862 650_7 $$2INSPIRE$$aanomalous dimension 000191862 650_7 $$2INSPIRE$$asuperspace 000191862 65020 $$2Author$$aSupersymmetry and Duality 000191862 65020 $$2Author$$aSuperspaces 000191862 65020 $$2Author$$aConformal and W Symmetry 000191862 65020 $$2Author$$aSigma Models 000191862 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000191862 7001_ $$0P:(DE-H253)PIP1004538$$aSchomerus, Volker$$b1$$udesy 000191862 7001_ $$0P:(DE-H253)PIP1015709$$aTlapak, Vaclav$$b2$$udesy 000191862 8564_ $$yRestricted 000191862 8564_ $$uhttps://bib-pubdb1.desy.de/record/191862/files/PUBDB-2014-04050.pdf$$yOpenAccess 000191862 8564_ $$uhttps://bib-pubdb1.desy.de/record/191862/files/PUBDB-2014-04050.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000191862 8564_ $$uhttps://bib-pubdb1.desy.de/record/191862/files/PUBDB-2014-04050.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000191862 8564_ $$uhttps://bib-pubdb1.desy.de/record/191862/files/PUBDB-2014-04050.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000191862 909CO $$ooai:bib-pubdb1.desy.de:191862$$pdnbdelivery$$pec_fundedresources$$pVDB$$pdriver$$popen_access$$popenaire 000191862 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1019541$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000191862 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1004538$$aDeutsches Elektronen-Synchrotron$$b1$$kDESY 000191862 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1015709$$aDeutsches Elektronen-Synchrotron$$b2$$kDESY 000191862 9132_ $$0G:(DE-HGF)POF3-611$$1G:(DE-HGF)POF3-610$$2G:(DE-HGF)POF3-600$$aDE-HGF$$bForschungsbereich Materie$$lMaterie und Universum$$vFundamental Particles and Forces $$x0 000191862 9131_ $$0G:(DE-HGF)POF2-514$$1G:(DE-HGF)POF2-510$$2G:(DE-HGF)POF2-500$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bStruktur der Materie$$lElementarteilchenphysik$$vTheoretical Particle Physics$$x0 000191862 9141_ $$y2014 000191862 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000191862 915__ $$0StatID:(DE-HGF)0580$$2StatID$$aPublished 000191862 9201_ $$0I:(DE-H253)T-20120731$$kT$$lTheorie-Gruppe$$x0 000191862 980__ $$apreprint 000191862 980__ $$aVDB 000191862 980__ $$aintrep 000191862 980__ $$aI:(DE-H253)T-20120731 000191862 980__ $$aUNRESTRICTED 000191862 9801_ $$aFullTexts
