Our results are very general and capture in particular line defects originating from bulk CFTs with a global symmetry, which can either be preserved or partially broken by the presence of the defect. We begin with an agnostic approach and perform a systematic bootstrap study of correlation functions between two canonical operators on the defect: the displacement and the tilt. We then focus on two interesting theories: a monodromy line defect and a localized magnetic field line defect. To this end, we combine the numerical bootstrap with the $\varepsilon$-expansion, where we complement existing results in the literature with additional calculations. For the monodromy defect our numerical results are consistent with expectations, with known analytic solutions sitting inside our numerical bounds. For the localized magnetic field line defect our plots show a series of intriguing cusps which we explore. 000481733 536__ $$0G:(DE-HGF)POF4-611$$a611 - Fundamental Particles and Forces (POF4-611)$$cPOF4-611$$fPOF IV$$x0 000481733 536__ $$0G:(DE-DFG)EmmyNoether$$aEmmy Noether - Emmy Noether Nachwuchsgruppe (EmmyNoether)$$cEmmyNoether$$x1 000481733 588__ $$aDataset connected to INSPIRE 000481733 650_7 $$2INSPIRE$$asymmetry, global 000481733 650_7 $$2INSPIRE$$afield theory, conformal 000481733 650_7 $$2INSPIRE$$adefect 000481733 650_7 $$2INSPIRE$$abootstrap 000481733 650_7 $$2INSPIRE$$amagnetic field 000481733 650_7 $$2INSPIRE$$amonodromy 000481733 650_7 $$2INSPIRE$$aO(2) 000481733 650_7 $$2INSPIRE$$acapture 000481733 650_7 $$2INSPIRE$$acorrelation function 000481733 650_7 $$2INSPIRE$$anumerical calculations 000481733 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000481733 7001_ $$0E.Lauria.1$$aLauria, Edoardo$$b1 000481733 7001_ $$0P:(DE-H253)PIP1031480$$aLiendo, Pedro$$b2 000481733 7001_ $$0P:(DE-H253)PIP1090382$$avan Vliet, Philine$$b3$$eCorresponding author$$udesy 000481733 8564_ $$uhttps://bib-pubdb1.desy.de/record/481733/files/HTML-Approval_of_scientific_publication.html 000481733 8564_ $$uhttps://bib-pubdb1.desy.de/record/481733/files/PDF-Approval_of_scientific_publication.pdf 000481733 8564_ $$uhttps://bib-pubdb1.desy.de/record/481733/files/2208.11715v1.pdf$$yOpenAccess 000481733 8564_ $$uhttps://bib-pubdb1.desy.de/record/481733/files/2208.11715v1.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000481733 909CO $$ooai:bib-pubdb1.desy.de:481733$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000481733 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1086631$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000481733 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1031480$$aDeutsches Elektronen-Synchrotron$$b2$$kDESY 000481733 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1090382$$aDeutsches Elektronen-Synchrotron$$b3$$kDESY 000481733 9131_ $$0G:(DE-HGF)POF4-611$$1G:(DE-HGF)POF4-610$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lMatter and the Universe$$vFundamental Particles and Forces$$x0 000481733 9141_ $$y2022 000481733 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000481733 915__ $$0StatID:(DE-HGF)0580$$2StatID$$aPublished 000481733 9201_ $$0I:(DE-H253)T-20120731$$kT$$lTheorie-Gruppe$$x0 000481733 980__ $$apreprint 000481733 980__ $$aVDB 000481733 980__ $$aUNRESTRICTED 000481733 980__ $$aI:(DE-H253)T-20120731 000481733 9801_ $$aFullTexts
